/**
 * An injectable service that produces an animation sequence programmatically within an
 * Angular component or directive.
 * Provided by the `BrowserAnimationsModule` or `NoopAnimationsModule`.
 *
 * @usageNotes
 *
 * To use this service, add it to your component or directive as a dependency.
 * The service is instantiated along with your component.
 *
 * Apps do not typically need to create their own animation players, but if you
 * do need to, follow these steps:
 *
 * 1. Use the <code>[AnimationBuilder.build](api/animations/AnimationBuilder#build)()</code> method
 * to create a programmatic animation. The method returns an `AnimationFactory` instance.
 *
 * 2. Use the factory object to create an `AnimationPlayer` and attach it to a DOM element.
 *
 * 3. Use the player object to control the animation programmatically.
 *
 * For example:
 *
 * ```ts
 * // import the service from BrowserAnimationsModule
 * import {AnimationBuilder} from '@angular/animations';
 * // require the service as a dependency
 * class MyCmp {
 *   constructor(private _builder: AnimationBuilder) {}
 *
 *   makeAnimation(element: any) {
 *     // first define a reusable animation
 *     const myAnimation = this._builder.build([
 *       style({ width: 0 }),
 *       animate(1000, style({ width: '100px' }))
 *     ]);
 *
 *     // use the returned factory object to create a player
 *     const player = myAnimation.create(element);
 *
 *     player.play();
 *   }
 * }
 * ```

const AUTO_STYLE = '*';
/**
 * Creates a named animation trigger, containing a  list of [`state()`](api/animations/state)
 * and `transition()` entries to be evaluated when the expression
 * bound to the trigger changes.
 *
 * @param name An identifying string.
 * @param definitions  An animation definition object, containing an array of
 * [`state()`](api/animations/state) and `transition()` declarations.
 *
 * @return An object that encapsulates the trigger data.
 *
 * @usageNotes
 * Define an animation trigger in the `animations` section of `@Component` metadata.
 * In the template, reference the trigger by name and bind it to a trigger expression that
 * evaluates to a defined animation state, using the following format:
 *
 * `[@triggerName]="expression"`
 *
 * Animation trigger bindings convert all values to strings, and then match the
 * previous and current values against any linked transitions.
 * Booleans can be specified as `1` or `true` and `0` or `false`.
 *
 * ### Usage Example
 *
 * The following example creates an animation trigger reference based on the provided
 * name value.
 * The provided animation value is expected to be an array consisting of state and
 * transition declarations.
 *
 * ```typescript
 * @Component({
 *   selector: "my-component",
 *   templateUrl: "my-component-tpl.html",
 *   animations: [
 *     trigger("myAnimationTrigger", [
 *       state(...),
 *       state(...),
 *       transition(...),
 *       transition(...)
 *     ])
 *   ]
 * })
 * class MyComponent {
 *   myStatusExp = "something";
 * }
 * ```
 *
 * The template associated with this component makes use of the defined trigger
 * by binding to an element within its template code.
 *
 * ```html
 * <!-- somewhere inside of my-component-tpl.html -->
 * <div [@myAnimationTrigger]="myStatusExp">...</div>
 * ```
 *
 * ### Using an inline function
 * The `transition` animation method also supports reading an inline function which can decide
 * if its associated animation should be run.
 *
 * ```typescript
 * // this method is run each time the `myAnimationTrigger` trigger value changes.
 * function myInlineMatcherFn(fromState: string, toState: string, element: any, params: {[key:
 string]: any}): boolean {
 *   // notice that `element` and `params` are also available here
 *   return toState == 'yes-please-animate';
 * }
 *
 * @Component({
 *   selector: 'my-component',
 *   templateUrl: 'my-component-tpl.html',
 *   animations: [
 *     trigger('myAnimationTrigger', [
 *       transition(myInlineMatcherFn, [
 *         // the animation sequence code
 *       ]),
 *     ])
 *   ]
 * })
 * class MyComponent {
 *   myStatusExp = "yes-please-animate";
 * }
 * ```
 *
 * ### Disabling Animations
 * When true, the special animation control binding `@.disabled` binding prevents
 * all animations from rendering.
 * Place the  `@.disabled` binding on an element to disable
 * animations on the element itself, as well as any inner animation triggers
 * within the element.
 *
 * The following example shows how to use this feature:
 *
 * ```typescript
 * @Component({
 *   selector: 'my-component',
 *   template: `
 *     <div [@.disabled]="isDisabled">
 *       <div [@childAnimation]="exp"></div>
 *     </div>
 *   `,
 *   animations: [
 *     trigger("childAnimation", [
 *       // ...
 *     ])
 *   ]
 * })
 * class MyComponent {
 *   isDisabled = true;
 *   exp = '...';
 * }
 * ```
 *
 * When `@.disabled` is true, it prevents the `@childAnimation` trigger from animating,
 * along with any inner animations.
 *
 * ### Disable animations application-wide
 * When an area of the template is set to have animations disabled,
 * **all** inner components have their animations disabled as well.
 * This means that you can disable all animations for an app
 * by placing a host binding set on `@.disabled` on the topmost Angular component.
 *
 * ```typescript
 * import {Component, HostBinding} from '@angular/core';
 *
 * @Component({
 *   selector: 'app-component',
 *   templateUrl: 'app.component.html',
 * })
 * class AppComponent {
 *   @HostBinding('@.disabled')
 *   public animationsDisabled = true;
 * }
 * ```
 *
 * ### Overriding disablement of inner animations
 * Despite inner animations being disabled, a parent animation can `query()`
 * for inner elements located in disabled areas of the template and still animate
 * them if needed. This is also the case for when a sub animation is
 * queried by a parent and then later animated using `animateChild()`.
 *
 * ### Detecting when an animation is disabled
 * If a region of the DOM (or the entire application) has its animations disabled, the animation
 * trigger callbacks still fire, but for zero seconds. When the callback fires, it provides
 * an instance of an `AnimationEvent`. If animations are disabled,
 * the `.disabled` flag on the event is true.

/**
 * Defines an animation step that combines styling information with timing information.
 *
 * @param timings Sets `AnimateTimings` for the parent animation.
 * A string in the format "duration [delay] [easing]".
 *  - Duration and delay are expressed as a number and optional time unit,
 * such as "1s" or "10ms" for one second and 10 milliseconds, respectively.
 * The default unit is milliseconds.
 *  - The easing value controls how the animation accelerates and decelerates
 * during its runtime. Value is one of  `ease`, `ease-in`, `ease-out`,
 * `ease-in-out`, or a `cubic-bezier()` function call.
 * If not supplied, no easing is applied.
 *
 * For example, the string "1s 100ms ease-out" specifies a duration of
 * 1000 milliseconds, and delay of 100 ms, and the "ease-out" easing style,
 * which decelerates near the end of the duration.
 * @param styles Sets AnimationStyles for the parent animation.
 * A function call to either `style()` or `keyframes()`
 * that returns a collection of CSS style entries to be applied to the parent animation.
 * When null, uses the styles from the destination state.
 * This is useful when describing an animation step that will complete an animation;
 * see "Animating to the final state" in `transitions()`.
 * @returns An object that encapsulates the animation step.
 *
 * @usageNotes
 * Call within an animation `sequence()`, `{@link animations/group group()}`, or
 * `transition()` call to specify an animation step
 * that applies given style data to the parent animation for a given amount of time.
 *
 * ### Syntax Examples
 * **Timing examples**
 *
 * The following examples show various `timings` specifications.
 * - `animate(500)` : Duration is 500 milliseconds.
 * - `animate("1s")` : Duration is 1000 milliseconds.
 * - `animate("100ms 0.5s")` : Duration is 100 milliseconds, delay is 500 milliseconds.
 * - `animate("5s ease-in")` : Duration is 5000 milliseconds, easing in.
 * - `animate("5s 10ms cubic-bezier(.17,.67,.88,.1)")` : Duration is 5000 milliseconds, delay is 10
 * milliseconds, easing according to a bezier curve.
 *
 * **Style examples**
 *
 * The following example calls `style()` to set a single CSS style.
 * ```typescript
 * animate(500, style({ background: "red" }))
 * ```
 * The following example calls `keyframes()` to set a CSS style
 * to different values for successive keyframes.
 * ```typescript
 * animate(500, keyframes(
 *  [
 *   style({ background: "blue" }),
 *   style({ background: "red" })
 *  ])
 * ```

 *
 * ### State Change Expression
 *
 * The State Change Expression instructs Angular when to run the transition's animations, it can
 *either be
 *  - a string with a specific syntax
 *  - or a function that compares the previous and current state (value of the expression bound to
 *    the element's trigger) and returns `true` if the transition should occur or `false` otherwise
 *
 * The string format can be:
 *  - `fromState => toState`, which indicates that the transition's animations should occur then the
 *    expression bound to the trigger's element goes from `fromState` to `toState`
 *
 *    _Example:_
 *      ```typescript
 *        transition('open => closed', animate('.5s ease-out', style({ height: 0 }) ))
 *      ```
 *
 *  - `fromState <=> toState`, which indicates that the transition's animations should occur then
 *    the expression bound to the trigger's element goes from `fromState` to `toState` or vice versa
 *
 *    _Example:_
 *      ```typescript
 *        transition('enabled <=> disabled', animate('1s cubic-bezier(0.8,0.3,0,1)'))
 *      ```
 *
 *  - `:enter`/`:leave`, which indicates that the transition's animations should occur when the
 *    element enters or exists the DOM
 *
 *    _Example:_
 *      ```typescript
 *        transition(':enter', [
 *          style({ opacity: 0 }),
 *          animate('500ms', style({ opacity: 1 }))
 *        ])
 *      ```
 *
 *  - `:increment`/`:decrement`, which indicates that the transition's animations should occur when
 *    the numerical expression bound to the trigger's element has increased in value or decreased
 *
 *    _Example:_
 *      ```typescript
 *        transition(':increment', query('@counter', animateChild()))
 *      ```
 *
 *  - a sequence of any of the above divided by commas, which indicates that transition's animations
 *    should occur whenever one of the state change expressions matches
 *
 *    _Example:_
 *      ```typescript
 *        transition(':increment, * => enabled, :enter', animate('1s ease', keyframes([
 *          style({ transform: 'scale(1)', offset: 0}),
 *          style({ transform: 'scale(1.1)', offset: 0.7}),
 *          style({ transform: 'scale(1)', offset: 1})
 *        ]))),
 *      ```
 *
 * Also note that in such context:
 *  - `void` can be used to indicate the absence of the element
 *  - asterisks can be used as wildcards that match any state
 *  - (as a consequence of the above, `void => *` is equivalent to `:enter` and `* => void` is
 *    equivalent to `:leave`)
 *  - `true` and `false` also match expression values of `1` and `0` respectively (but do not match
 *    _truthy_ and _falsy_ values)
 *
 * <div class="alert is-helpful">
 *
 *  Be careful about entering end leaving elements as their transitions present a common
 *  pitfall for developers.
 *
 *  Note that when an element with a trigger enters the DOM its `:enter` transition always
 *  gets executed, but its `:leave` transition will not be executed if the element is removed
 *  alongside its parent (as it will be removed "without warning" before its transition has
 *  a chance to be executed, the only way that such transition can occur is if the element
 *  is exiting the DOM on its own).
 *
 *
 * </div>
 *
 * ### Animating to a Final State
 *
 * If the final step in a transition is a call to `animate()` that uses a timing value
 * with no `style` data, that step is automatically considered the final animation arc,
 * for the element to reach the final state, in such case Angular automatically adds or removes
 * CSS styles to ensure that the element is in the correct final state.
 *
 *
 * ### Usage Examples
 *
 *  - Transition animations applied based on
 *    the trigger's expression value
 *
 *   ```HTML
 *   <div [@myAnimationTrigger]="myStatusExp">
 *    ...
 *   </div>
 *   ```
 *
 *   ```typescript
 *   trigger("myAnimationTrigger", [
 *     ..., // states
 *     transition("on => off, open => closed", animate(500)),
 *     transition("* <=> error", query('.indicator', animateChild()))
 *   ])
 *   ```
 *
 *  - Transition animations applied based on custom logic dependent
 *    on the trigger's expression value and provided parameters
 *
 *    ```HTML
 *    <div [@myAnimationTrigger]="{
 *     value: stepName,
 *     params: { target: currentTarget }
 *    }">
 *     ...
 *    </div>
 *    ```
 *
 *    ```typescript
 *    trigger("myAnimationTrigger", [
 *      ..., // states
 *      transition(
 *        (fromState, toState, _element, params) =>
 *          ['firststep', 'laststep'].includes(fromState.toLowerCase())
 *          && toState === params?.['target'],
 *        animate('1s')
 *      )
 *    ])
 *    ```

 * Produces a reusable animation that can be invoked in another animation or sequence,

 *
 * @param steps One or more animation objects, as returned by the `animate()`
 * or `sequence()` function, that form a transformation from one state to another.
 * A sequence is used by default when you pass an array.
 * @param options An options object that can contain a delay value for the start of the
 * animation, and additional developer-defined parameters.
 * Provided values for additional parameters are used as defaults,
 * and override values can be passed to the caller on invocation.
 * @returns An object that encapsulates the animation data.
 *
 * @usageNotes
 * The following example defines a reusable animation, providing some default parameter
 * values.
 *
 * ```typescript
 * var fadeAnimation = animation([
 *   style({ opacity: '{{ start }}' }),
 *   animate('{{ time }}',
 *   style({ opacity: '{{ end }}'}))
 *   ],
 *   { params: { time: '1000ms', start: 0, end: 1 }});
 * ```
 *
 * The following invokes the defined animation with a call to `useAnimation()`,
 * passing in override parameter values.
 *
 * ```js
 * useAnimation(fadeAnimation, {
 *   params: {
 *     time: '2s',
 *     start: 1,
 *     end: 0
 *   }
 * })
 * ```
 *
 * If any of the passed-in parameter values are missing from this call,
 * the default values are used. If one or more parameter values are missing before a step is
 * animated, `useAnimation()` throws an error.

/**

 * @param selector The element to query, or a set of elements that contain Angular-specific

 *  - `query(":enter")` or `query(":leave")` : Query for newly inserted/removed elements (not
 *     all elements can be queried via these tokens, see
 *     [Entering and Leaving Elements](#entering-and-leaving-elements))
 *  - `query(":animating")` : Query all currently animating elements.
 *  - `query("@triggerName")` : Query elements that contain an animation trigger.
 *  - `query("@*")` : Query all elements that contain an animation triggers.
 *  - `query(":self")` : Include the current element into the animation sequence.
 *
 * @param animation One or more animation steps to apply to the queried element or elements.
 * An array is treated as an animation sequence.
 * @param options An options object. Use the 'limit' field to limit the total number of
 * items to collect.
 * @return An object that encapsulates the query data.
 *
 * @usageNotes
 *
 * ### Multiple Tokens
 *
 * Tokens can be merged into a combined query selector string. For example:
 *
 * ```typescript
 *  query(':self, .record:enter, .record:leave, @subTrigger', [...])
 * ```
 *
 * The `query()` function collects multiple elements and works internally by using
 * `element.querySelectorAll`. Use the `limit` field of an options object to limit
 * the total number of items to be collected. For example:
 *
 * ```js
 * query('div', [
 *   animate(...),
 *   animate(...)
 * ], { limit: 1 })
 * ```
 *
 * By default, throws an error when zero items are found. Set the
 * `optional` flag to ignore this error. For example:
 *
 * ```js
 * query('.some-element-that-may-not-be-there', [
 *   animate(...),
 *   animate(...)
 * ], { optional: true })
 * ```
 *
 * ### Entering and Leaving Elements
 *
 * Not all elements can be queried via the `:enter` and `:leave` tokens, the only ones
 * that can are those that Angular assumes can enter/leave based on their own logic
 * (if their insertion/removal is simply a consequence of that of their parent they
 * should be queried via a different token in their parent's `:enter`/`:leave` transitions).
 *
 * The only elements Angular assumes can enter/leave based on their own logic (thus the only
 * ones that can be queried via the `:enter` and `:leave` tokens) are:
 *  - Those inserted dynamically (via `ViewContainerRef`)
 *  - Those that have a structural directive (which, under the hood, are a subset of the above ones)
 *
 * <div class="alert is-helpful">
 *
 *  Note that elements will be successfully queried via `:enter`/`:leave` even if their
 *  insertion/removal is not done manually via `ViewContainerRef`or caused by their structural
 *  directive (e.g. they enter/exit alongside their parent).
 *
 * </div>
 *
 * <div class="alert is-important">
 *
 *  There is an exception to what previously mentioned, besides elements entering/leaving based on
 *  their own logic, elements with an animation trigger can always be queried via `:leave` when
 * their parent is also leaving.
 *
 * </div>
 *
 * ### Usage Example
 *
 * The following example queries for inner elements and animates them
 * individually using `animate()`.
 *
 * ```typescript
 * @Component({
 *   selector: 'inner',
 *   template: `
 *     <div [@queryAnimation]="exp">
 *       <h1>Title</h1>
 *       <div class="content">
 *         Blah blah blah
 *       </div>
 *     </div>
 *   `,
 *   animations: [
 *    trigger('queryAnimation', [
 *      transition('* => goAnimate', [
 *        // hide the inner elements
 *        query('h1', style({ opacity: 0 })),
 *        query('.content', style({ opacity: 0 })),
 *
 *        // animate the inner elements in, one by one
 *        query('h1', animate(1000, style({ opacity: 1 }))),
 *        query('.content', animate(1000, style({ opacity: 1 }))),
 *      ])
 *    ])
 *  ]
 * })
 * class Cmp {
 *   exp = '';
 *
 *   goAnimate() {
 *     this.exp = 'goAnimate';
 *   }
 * }
 * ```

 *
 * Each time items are added, the opacity fade-in animation runs,
 * and each removed item is faded out.
 * When either of these animations occur, the stagger effect is
 * applied after each item's animation is started.

/*
 * [Validation]
 * The visitor code below will traverse the animation AST generated by the animation verb functions
 * (the output is a tree of objects) and attempt to perform a series of validations on the data. The
 * following corner-cases will be validated:
 *
 * 1. Overlap of animations
 * Given that a CSS property cannot be animated in more than one place at the same time, it's
 * important that this behavior is detected and validated. The way in which this occurs is that
 * each time a style property is examined, a string-map containing the property will be updated with
 * the start and end times for when the property is used within an animation step.
 *
 * If there are two or more parallel animations that are currently running (these are invoked by the
 * group()) on the same element then the validator will throw an error. Since the start/end timing
 * values are collected for each property then if the current animation step is animating the same
 * property and its timing values fall anywhere into the window of time that the property is
 * currently being animated within then this is what causes an error.
 *
 * 2. Timing values
 * The validator will validate to see if a timing value of `duration delay easing` or
 * `durationNumber` is valid or not.
 *
 * (note that upon validation the code below will replace the timing data with an object containing
 * {duration,delay,easing}.
 *
 * 3. Offset Validation
 * Each of the style() calls are allowed to have an offset value when placed inside of keyframes().
 * Offsets within keyframes() are considered valid when:
 *
 *   - No offsets are used at all
 *   - Each style() entry contains an offset value
 *   - Each offset is between 0 and 1
 *   - Each offset is greater to or equal than the previous one
 *
 * Otherwise an error will be thrown.

/*
 * The code within this file aims to generate web-animations-compatible keyframes from Angular's
 * animation DSL code.
 *
 * The code below will be converted from:
 *
 * ```
 * sequence([
 *   style({ opacity: 0 }),
 *   animate(1000, style({ opacity: 0 }))
 * ])
 * ```
 *
 * To:
 * ```
 * keyframes = [{ opacity: 0, offset: 0 }, { opacity: 1, offset: 1 }]
 * duration = 1000
 * delay = 0
 * easing = ''
 * ```
 *
 * For this operation to cover the combination of animation verbs (style, animate, group, etc...) a
 * combination of AST traversal and merge-sort-like algorithms are used.
 *
 * [AST Traversal]
 * Each of the animation verbs, when executed, will return an string-map object representing what
 * type of action it is (style, animate, group, etc...) and the data associated with it. This means
 * that when functional composition mix of these functions is evaluated (like in the example above)
 * then it will end up producing a tree of objects representing the animation itself.
 *
 * When this animation object tree is processed by the visitor code below it will visit each of the
 * verb statements within the visitor. And during each visit it will build the context of the
 * animation keyframes by interacting with the `TimelineBuilder`.
 *
 * [TimelineBuilder]
 * This class is responsible for tracking the styles and building a series of keyframe objects for a
 * timeline between a start and end time. The builder starts off with an initial timeline and each
 * time the AST comes across a `group()`, `keyframes()` or a combination of the two within a
 * `sequence()` then it will generate a sub timeline for each step as well as a new one after
 * they are complete.
 *
 * As the AST is traversed, the timing state on each of the timelines will be incremented. If a sub
 * timeline was created (based on one of the cases above) then the parent timeline will attempt to
 * merge the styles used within the sub timelines into itself (only with group() this will happen).
 * This happens with a merge operation (much like how the merge works in mergeSort) and it will only
 * copy the most recently used styles from the sub timelines into the parent timeline. This ensures
 * that if the styles are used later on in another phase of the animation then they will be the most
 * up-to-date values.
 *
 * [How Missing Styles Are Updated]
 * Each timeline has a `backFill` property which is responsible for filling in new styles into
 * already processed keyframes if a new style shows up later within the animation sequence.
 *
 * ```
 * sequence([
 *   style({ width: 0 }),
 *   animate(1000, style({ width: 100 })),
 *   animate(1000, style({ width: 200 })),
 *   animate(1000, style({ width: 300 }))
 *   animate(1000, style({ width: 400, height: 400 })) // notice how `height` doesn't exist anywhere
 * else
 * ])
 * ```
 *
 * What is happening here is that the `height` value is added later in the sequence, but is missing
 * from all previous animation steps. Therefore when a keyframe is created it would also be missing
 * from all previous keyframes up until where it is first used. For the timeline keyframe generation
 * to properly fill in the style it will place the previous value (the value from the parent
 * timeline) or a default value of `*` into the backFill map. The `copyStyles` method in util.ts
 * handles propagating that backfill map to the styles object.
 *
 * When a sub-timeline is created it will have its own backFill property. This is done so that
 * styles present within the sub-timeline do not accidentally seep into the previous/future timeline
 * keyframes
 *
 * [Validation]
 * The code in this file is not responsible for validation. That functionality happens with within
 * the `AnimationValidatorVisitor` code.

/**
 * Instantiates a {@link Component} type and inserts its Host View into the current View.
 * `NgComponentOutlet` provides a declarative approach for dynamic component creation.
 *
 * `NgComponentOutlet` requires a component type, if a falsy value is set the view will clear and
 * any existing component will be destroyed.
 *
 * @usageNotes
 *
 * ### Fine tune control
 *
 * You can control the component creation process by using the following optional attributes:
 *
 * * `ngComponentOutletInjector`: Optional custom {@link Injector} that will be used as parent for
 * the Component. Defaults to the injector of the current view container.
 *
 * * `ngComponentOutletContent`: Optional list of projectable nodes to insert into the content
 * section of the component, if it exists.
 *
 * * `ngComponentOutletNgModule`: Optional NgModule class reference to allow loading another
 * module dynamically, then loading a component from that module.
 *
 * * `ngComponentOutletNgModuleFactory`: Deprecated config option that allows providing optional
 * NgModule factory to allow loading another module dynamically, then loading a component from that
 * module. Use `ngComponentOutletNgModule` instead.
 *
 * ### Syntax
 *
 * Simple
 * ```
 * <ng-container *ngComponentOutlet="componentTypeExpression"></ng-container>
 * ```
 *
 * Customized injector/content
 * ```
 * <ng-container *ngComponentOutlet="componentTypeExpression;
 *                                   injector: injectorExpression;
 *                                   content: contentNodesExpression;">
 * </ng-container>
 * ```
 *
 * Customized NgModule reference
 * ```
 * <ng-container *ngComponentOutlet="componentTypeExpression;
 *                                   ngModule: ngModuleClass;">
 * </ng-container>
 * ```
 *
 * ### A simple example
 *
 * {@example common/ngComponentOutlet/ts/module.ts region='SimpleExample'}
 *
 * A more complete example with additional options:
 *
 * {@example common/ngComponentOutlet/ts/module.ts region='CompleteExample'}

/**
 * A [structural directive](guide/structural-directives) that renders
 * a template for each item in a collection.
 * The directive is placed on an element, which becomes the parent
 * of the cloned templates.
 *
 * The `ngForOf` directive is generally used in the
 * [shorthand form](guide/structural-directives#asterisk) `*ngFor`.
 * In this form, the template to be rendered for each iteration is the content
 * of an anchor element containing the directive.
 *
 * The following example shows the shorthand syntax with some options,
 * contained in an `<li>` element.
 *
 * ```
 * <li *ngFor="let item of items; index as i; trackBy: trackByFn">...</li>
 * ```
 *
 * The shorthand form expands into a long form that uses the `ngForOf` selector
 * on an `<ng-template>` element.
 * The content of the `<ng-template>` element is the `<li>` element that held the
 * short-form directive.
 *
 * Here is the expanded version of the short-form example.
 *
 * ```
 * <ng-template ngFor let-item [ngForOf]="items" let-i="index" [ngForTrackBy]="trackByFn">
 *   <li>...</li>
 * </ng-template>
 * ```
 *
 * Angular automatically expands the shorthand syntax as it compiles the template.
 * The context for each embedded view is logically merged to the current component
 * context according to its lexical position.
 *
 * When using the shorthand syntax, Angular allows only [one structural directive
 * on an element](guide/structural-directives#one-per-element).
 * If you want to iterate conditionally, for example,
 * put the `*ngIf` on a container element that wraps the `*ngFor` element.
 * For further discussion, see
 * [Structural Directives](guide/structural-directives#one-per-element).
 *
 * @usageNotes
 *
 * ### Local variables
 *
 * `NgForOf` provides exported values that can be aliased to local variables.
 * For example:
 *
 *  ```
 * <li *ngFor="let user of users; index as i; first as isFirst">
 *    {{i}}/{{users.length}}. {{user}} <span *ngIf="isFirst">default</span>
 * </li>
 * ```
 *
 * The following exported values can be aliased to local variables:
 *
 * - `$implicit: T`: The value of the individual items in the iterable (`ngForOf`).
 * - `ngForOf: NgIterable<T>`: The value of the iterable expression. Useful when the expression is
 * more complex then a property access, for example when using the async pipe (`userStreams |
 * async`).
 * - `index: number`: The index of the current item in the iterable.
 * - `count: number`: The length of the iterable.
 * - `first: boolean`: True when the item is the first item in the iterable.
 * - `last: boolean`: True when the item is the last item in the iterable.
 * - `even: boolean`: True when the item has an even index in the iterable.
 * - `odd: boolean`: True when the item has an odd index in the iterable.
 *
 * ### Change propagation
 *
 * When the contents of the iterator changes, `NgForOf` makes the corresponding changes to the DOM:
 *
 * * When an item is added, a new instance of the template is added to the DOM.
 * * When an item is removed, its template instance is removed from the DOM.
 * * When items are reordered, their respective templates are reordered in the DOM.
 *
 * Angular uses object identity to track insertions and deletions within the iterator and reproduce
 * those changes in the DOM. This has important implications for animations and any stateful
 * controls that are present, such as `<input>` elements that accept user input. Inserted rows can
 * be animated in, deleted rows can be animated out, and unchanged rows retain any unsaved state
 * such as user input.
 * For more on animations, see [Transitions and Triggers](guide/transition-and-triggers).
 *
 * The identities of elements in the iterator can change while the data does not.
 * This can happen, for example, if the iterator is produced from an RPC to the server, and that
 * RPC is re-run. Even if the data hasn't changed, the second response produces objects with
 * different identities, and Angular must tear down the entire DOM and rebuild it (as if all old
 * elements were deleted and all new elements inserted).
 *
 * To avoid this expensive operation, you can customize the default tracking algorithm.
 * by supplying the `trackBy` option to `NgForOf`.
 * `trackBy` takes a function that has two arguments: `index` and `item`.
 * If `trackBy` is given, Angular tracks changes by the return value of the function.
 *

/**
 * A structural directive that conditionally includes a template based on the value of

 * When the expression evaluates to true, Angular renders the template
 * provided in a `then` clause, and when  false or null,
 * Angular renders the template provided in an optional `else` clause. The default
 * template for the `else` clause is blank.
 *
 * A [shorthand form](guide/structural-directives#asterisk) of the directive,
 * `*ngIf="condition"`, is generally used, provided
 * as an attribute of the anchor element for the inserted template.
 * Angular expands this into a more explicit version, in which the anchor element
 * is contained in an `<ng-template>` element.
 *
 * Simple form with shorthand syntax:
 *
 * ```
 * <div *ngIf="condition">Content to render when condition is true.</div>
 * ```
 *
 * Simple form with expanded syntax:
 *
 * ```
 * <ng-template [ngIf]="condition"><div>Content to render when condition is
 * true.</div></ng-template>
 * ```
 *
 * Form with an "else" block:
 *

 *
 * Form with storing the value locally:
 *
 * ```
 * <div *ngIf="condition as value; else elseBlock">{{value}}</div>
 * <ng-template #elseBlock>Content to render when value is null.</ng-template>
 * ```
 *
 * @usageNotes
 *
 * The `*ngIf` directive is most commonly used to conditionally show an inline template,
 * as seen in the following  example.
 * The default `else` template is blank.
 *
 * {@example common/ngIf/ts/module.ts region='NgIfSimple'}
 *
 * ### Showing an alternative template using `else`
 *
 * To display a template when `expression` evaluates to false, use an `else` template
 * binding as shown in the following example.
 * The `else` binding points to an `<ng-template>`  element labeled `#elseBlock`.
 * The template can be defined anywhere in the component view, but is typically placed right after
 * `ngIf` for readability.
 *
 * {@example common/ngIf/ts/module.ts region='NgIfElse'}
 *
 * ### Using an external `then` template
 *
 * In the previous example, the then-clause template is specified inline, as the content of the
 * tag that contains the `ngIf` directive. You can also specify a template that is defined
 * externally, by referencing a labeled `<ng-template>` element. When you do this, you can
 * change which template to use at runtime, as shown in the following example.
 *
 * {@example common/ngIf/ts/module.ts region='NgIfThenElse'}
 *
 * ### Storing a conditional result in a variable
 *
 * You might want to show a set of properties from the same object. If you are waiting
 * for asynchronous data, the object can be undefined.
 * In this case, you can use `ngIf` and store the result of the condition in a local
 * variable as shown in the following example.
 *
 * {@example common/ngIf/ts/module.ts region='NgIfAs'}
 *
 * This code uses only one `AsyncPipe`, so only one subscription is created.
 * The conditional statement stores the result of `userStream|async` in the local variable `user`.
 * You can then bind the local `user` repeatedly.
 *
 * The conditional displays the data only if `userStream` returns a value,
 * so you don't need to use the
 * safe-navigation-operator (`?.`)
 * to guard against null values when accessing properties.
 * You can display an alternative template while waiting for the data.
 *
 * ### Shorthand syntax
 *
 * The shorthand syntax `*ngIf` expands into two separate template specifications
 * for the "then" and "else" clauses. For example, consider the following shorthand statement,
 * that is meant to show a loading page while waiting for data to be loaded.
 *
 * ```
 * <div class="hero-list" *ngIf="heroes else loading">
 *  ...
 * </div>
 *
 * <ng-template #loading>
 *  <div>Loading...</div>
 * </ng-template>
 * ```
 *
 * You can see that the "else" clause references the `<ng-template>`
 * with the `#loading` label, and the template for the "then" clause
 * is provided as the content of the anchor element.
 *
 * However, when Angular expands the shorthand syntax, it creates
 * another `<ng-template>` tag, with `ngIf` and `ngIfElse` directives.
 * The anchor element containing the template for the "then" clause becomes
 * the content of this unlabeled `<ng-template>` tag.
 *
 * ```
 * <ng-template [ngIf]="heroes" [ngIfElse]="loading">
 *  <div class="hero-list">
 *   ...
 *  </div>
 * </ng-template>
 *
 * <ng-template #loading>
 *  <div>Loading...</div>
 * </ng-template>
 * ```
 *
 * The presence of the implicit template object has implications for the nesting of
 * structural directives. For more on this subject, see
 * [Structural Directives](guide/structural-directives#one-per-element).

/**
 * @ngModule CommonModule
 *
 * @description
 * The `[ngSwitch]` directive on a container specifies an expression to match against.
 * The expressions to match are provided by `ngSwitchCase` directives on views within the container.
 * - Every view that matches is rendered.
 * - If there are no matches, a view with the `ngSwitchDefault` directive is rendered.
 * - Elements within the `[NgSwitch]` statement but outside of any `NgSwitchCase`
 * or `ngSwitchDefault` directive are preserved at the location.
 *
 * @usageNotes
 * Define a container element for the directive, and specify the switch expression
 * to match against as an attribute:
 *
 * ```
 * <container-element [ngSwitch]="switch_expression">
 * ```
 *
 * Within the container, `*ngSwitchCase` statements specify the match expressions
 * as attributes. Include `*ngSwitchDefault` as the final case.
 *
 * ```
 * <container-element [ngSwitch]="switch_expression">
 *    <some-element *ngSwitchCase="match_expression_1">...</some-element>
 * ...
 *    <some-element *ngSwitchDefault>...</some-element>
 * </container-element>
 * ```
 *
 * ### Usage Examples
 *
 * The following example shows how to use more than one case to display the same view:
 *
 * ```
 * <container-element [ngSwitch]="switch_expression">
 *   <!-- the same view can be shown in more than one case -->
 *   <some-element *ngSwitchCase="match_expression_1">...</some-element>
 *   <some-element *ngSwitchCase="match_expression_2">...</some-element>
 *   <some-other-element *ngSwitchCase="match_expression_3">...</some-other-element>
 *   <!--default case when there are no matches -->
 *   <some-element *ngSwitchDefault>...</some-element>
 * </container-element>
 * ```
 *
 * The following example shows how cases can be nested:
 * ```
 * <container-element [ngSwitch]="switch_expression">
 *       <some-element *ngSwitchCase="match_expression_1">...</some-element>
 *       <some-element *ngSwitchCase="match_expression_2">...</some-element>
 *       <some-other-element *ngSwitchCase="match_expression_3">...</some-other-element>
 *       <ng-container *ngSwitchCase="match_expression_3">
 *         <!-- use a ng-container to group multiple root nodes -->
 *         <inner-element></inner-element>
 *         <inner-other-element></inner-other-element>
 *       </ng-container>
 *       <some-element *ngSwitchDefault>...</some-element>
 *     </container-element>
 * ```

 *
 * Unwraps a value from an asynchronous primitive.
 *
 * The `async` pipe subscribes to an `Observable` or `Promise` and returns the latest value it has
 * emitted. When a new value is emitted, the `async` pipe marks the component to be checked for
 * changes. When the component gets destroyed, the `async` pipe unsubscribes automatically to avoid
 * potential memory leaks. When the reference of the expression changes, the `async` pipe
 * automatically unsubscribes from the old `Observable` or `Promise` and subscribes to the new one.
 *
 * @usageNotes
 *
 * ### Examples
 *
 * This example binds a `Promise` to the view. Clicking the `Resolve` button resolves the
 * promise.
 *
 * {@example common/pipes/ts/async_pipe.ts region='AsyncPipePromise'}
 *
 * It's also possible to use `async` with Observables. The example below binds the `time` Observable
 * to the view. The Observable continuously updates the view with the current time.

/**
 * @ngModule CommonModule
 * @description
 *
 * Formats a date value according to locale rules.
 *
 * `DatePipe` is executed only when it detects a pure change to the input value.
 * A pure change is either a change to a primitive input value
 * (such as `String`, `Number`, `Boolean`, or `Symbol`),
 * or a changed object reference (such as `Date`, `Array`, `Function`, or `Object`).
 *
 * Note that mutating a `Date` object does not cause the pipe to be rendered again.
 * To ensure that the pipe is executed, you must create a new `Date` object.
 *
 * Only the `en-US` locale data comes with Angular. To localize dates
 * in another language, you must import the corresponding locale data.
 * See the [I18n guide](guide/i18n-common-format-data-locale) for more information.
 *
 * The time zone of the formatted value can be specified either by passing it in as the second
 * parameter of the pipe, or by setting the default through the `DATE_PIPE_DEFAULT_TIMEZONE`
 * injection token. The value that is passed in as the second parameter takes precedence over
 * the one defined using the injection token.
 *
 * @see `formatDate()`
 *
 *
 * @usageNotes
 *
 * The result of this pipe is not reevaluated when the input is mutated. To avoid the need to
 * reformat the date on every change-detection cycle, treat the date as an immutable object
 * and change the reference when the pipe needs to run again.
 *
 * ### Pre-defined format options
 *
 * | Option        | Equivalent to                       | Examples (given in `en-US` locale)              |

 * ### Format examples
 *
 * These examples transform a date into various formats,
 * assuming that `dateObj` is a JavaScript `Date` object for
 * year: 2015, month: 6, day: 15, hour: 21, minute: 43, second: 11,
 * given in the local time for the `en-US` locale.
 *
 * ```
 * {{ dateObj | date }}               // output is 'Jun 15, 2015'
 * {{ dateObj | date:'medium' }}      // output is 'Jun 15, 2015, 9:43:11 PM'
 * {{ dateObj | date:'shortTime' }}   // output is '9:43 PM'
 * {{ dateObj | date:'mm:ss' }}       // output is '43:11'
 * ```
 *
 * ### Usage example
 *
 * The following component uses a date pipe to display the current date in different formats.
 *
 * ```
 * @Component({
 *  selector: 'date-pipe',
 *  template: `<div>
 *    <p>Today is {{today | date}}</p>
 *    <p>Or if you prefer, {{today | date:'fullDate'}}</p>
 *    <p>The time is {{today | date:'h:mm a z'}}</p>
 *  </div>`
 * })
 * // Get the current date and time as a date-time value.
 * export class DatePipeComponent {
 *   today: number = Date.now();
 * }
 * ```
 *

 *
 * ### digitsInfo
 *
 * The value's decimal representation is specified by the `digitsInfo`
 * parameter, written in the following format:<br>
 *
 * ```
 * {minIntegerDigits}.{minFractionDigits}-{maxFractionDigits}
 * ```
 *
 *  - `minIntegerDigits`:

 * - `minFractionDigits`:
 * The minimum number of digits after the decimal point.
 * Default is 0.
 *
 *  - `maxFractionDigits`:
 * The maximum number of digits after the decimal point.
 * Default is 3.
 *
 * If the formatted value is truncated it will be rounded using the "to-nearest" method:

 * {{3.6 | number: '1.0-0'}}
 * <!--will output '4'-->
 *
 * {{-3.6 | number:'1.0-0'}}
 * <!--will output '-4'-->
 * ```
 *
 * ### locale
 *
 * `locale` will format a value according to locale rules.
 * Locale determines group sizing and separator,
 * decimal point character, and other locale-specific configurations.
 *
 * When not supplied, uses the value of `LOCALE_ID`, which is `en-US` by default.
 *
 * See [Setting your app locale](guide/i18n-common-locale-id).

   * such as `USD` for the US dollar and `EUR` for the euro. The default currency code can be
   * configured using the `DEFAULT_CURRENCY_CODE` injection token.
   * @param display The format for the currency indicator. One of the following:
   *   - `code`: Show the code (such as `USD`).
   *   - `symbol`(default): Show the symbol (such as `$`).
   *   - `symbol-narrow`: Use the narrow symbol for locales that have two symbols for their
   * currency.
   * For example, the Canadian dollar CAD has the symbol `CA$` and the symbol-narrow `$`. If the
   * locale has no narrow symbol, uses the standard symbol for the locale.
   *   - String: Use the given string value instead of a code or a symbol.
   * For example, an empty string will suppress the currency & symbol.
   *   - Boolean (marked deprecated in v5): `true` for symbol and false for `code`.
   *
   * @param digitsInfo Decimal representation options, specified by a string
   * in the following format:<br>
   * <code>{minIntegerDigits}.{minFractionDigits}-{maxFractionDigits}</code>.
   *   - `minIntegerDigits`: The minimum number of integer digits before the decimal point.
   * Default is `1`.
   *   - `minFractionDigits`: The minimum number of digits after the decimal point.
   * Default is `2`.
   *   - `maxFractionDigits`: The maximum number of digits after the decimal point.
   * Default is `2`.
   * If not provided, the number will be formatted with the proper amount of digits,
   * depending on what the [ISO 4217](https://en.wikipedia.org/wiki/ISO_4217) specifies.
   * For example, the Canadian dollar has 2 digits, whereas the Chilean peso has none.
   * @param locale A locale code for the locale format rules to use.
   * When not supplied, uses the value of `LOCALE_ID`, which is `en-US` by default.
   * See [Setting your app locale](guide/i18n-common-locale-id).

/**
 * Directive that improves image loading performance by enforcing best practices.
 *
 * `NgOptimizedImage` ensures that the loading of the Largest Contentful Paint (LCP) image is
 * prioritized by:
 * - Automatically setting the `fetchpriority` attribute on the `<img>` tag
 * - Lazy loading non-priority images by default
 * - Asserting that there is a corresponding preconnect link tag in the document head
 *
 * In addition, the directive:
 * - Generates appropriate asset URLs if a corresponding `ImageLoader` function is provided
 * - Automatically generates a srcset
 * - Requires that `width` and `height` are set
 * - Warns if `width` or `height` have been set incorrectly
 * - Warns if the image will be visually distorted when rendered
 *
 * @usageNotes
 * The `NgOptimizedImage` directive is marked as [standalone](guide/standalone-components) and can
 * be imported directly.
 *
 * Follow the steps below to enable and use the directive:
 * 1. Import it into the necessary NgModule or a standalone Component.
 * 2. Optionally provide an `ImageLoader` if you use an image hosting service.
 * 3. Update the necessary `<img>` tags in templates and replace `src` attributes with `ngSrc`.
 * Using a `ngSrc` allows the directive to control when the `src` gets set, which triggers an image
 * download.
 *
 * Step 1: import the `NgOptimizedImage` directive.
 *
 * ```typescript
 * import { NgOptimizedImage } from '@angular/common';
 *
 * // Include it into the necessary NgModule
 * @NgModule({
 *   imports: [NgOptimizedImage],
 * })
 * class AppModule {}
 *
 * // ... or a standalone Component
 * @Component({
 *   standalone: true
 *   imports: [NgOptimizedImage],
 * })
 * class MyStandaloneComponent {}
 * ```
 *
 * Step 2: configure a loader.
 *
 * To use the **default loader**: no additional code changes are necessary. The URL returned by the
 * generic loader will always match the value of "src". In other words, this loader applies no
 * transformations to the resource URL and the value of the `ngSrc` attribute will be used as is.
 *
 * To use an existing loader for a **third-party image service**: add the provider factory for your
 * chosen service to the `providers` array. In the example below, the Imgix loader is used:
 *
 * ```typescript
 * import {provideImgixLoader} from '@angular/common';
 *
 * // Call the function and add the result to the `providers` array:
 * providers: [
 *   provideImgixLoader("https://my.base.url/"),
 * ],
 * ```
 *
 * The `NgOptimizedImage` directive provides the following functions:
 * - `provideCloudflareLoader`
 * - `provideCloudinaryLoader`
 * - `provideImageKitLoader`
 * - `provideImgixLoader`
 *
 * If you use a different image provider, you can create a custom loader function as described
 * below.
 *
 * To use a **custom loader**: provide your loader function as a value for the `IMAGE_LOADER` DI
 * token.
 *
 * ```typescript
 * import {IMAGE_LOADER, ImageLoaderConfig} from '@angular/common';
 *
 * // Configure the loader using the `IMAGE_LOADER` token.
 * providers: [
 *   {
 *      provide: IMAGE_LOADER,
 *      useValue: (config: ImageLoaderConfig) => {
 *        return `https://example.com/${config.src}-${config.width}.jpg}`;
 *      }
 *   },
 * ],
 * ```
 *
 * Step 3: update `<img>` tags in templates to use `ngSrc` instead of `src`.
 *
 * ```
 * <img ngSrc="logo.png" width="200" height="100">
 * ```
 *

 * Performs HTTP requests.
 * This service is available as an injectable class, with methods to perform HTTP requests.
 * Each request method has multiple signatures, and the return type varies based on
 * the signature that is called (mainly the values of `observe` and `responseType`).
 *
 * Note that the `responseType` *options* value is a String that identifies the
 * single data type of the response.

 * The value of `responseType` cannot be a union, as the combined signature could imply.

 *
 * @usageNotes
 * Sample HTTP requests for the [Tour of Heroes](/tutorial/toh-pt0) application.
 *
 * ### HTTP Request Example
 *
 * ```
 *  // GET heroes whose name contains search term
 * searchHeroes(term: string): observable<Hero[]>{
 *
 *  const params = new HttpParams({fromString: 'name=term'});
 *    return this.httpClient.request('GET', this.heroesUrl, {responseType:'json', params});
 * }
 * ```
 *
 * Alternatively, the parameter string can be used without invoking HttpParams
 * by directly joining to the URL.
 * ```
 * this.httpClient.request('GET', this.heroesUrl + '?' + 'name=term', {responseType:'json'});
 * ```
 *
 *
 * ### JSONP Example
 * ```
 * requestJsonp(url, callback = 'callback') {
 *  return this.httpClient.jsonp(this.heroesURL, callback);
 * }
 * ```
 *
 * ### PATCH Example
 * ```
 * // PATCH one of the heroes' name
 * patchHero (id: number, heroName: string): Observable<{}> {
 * const url = `${this.heroesUrl}/${id}`;   // PATCH api/heroes/42
 *  return this.httpClient.patch(url, {name: heroName}, httpOptions)
 *    .pipe(catchError(this.handleError('patchHero')));
 * }

 * This method is used with `factory` functions which are generated as part of
 * `defineDirective` or `defineComponent`. The method retrieves the static value
 * of an attribute. (Dynamic attributes are not supported since they are not resolved
 *  at the time of injection and can change over time.)
 *
 * # Example
 * Given:
 * ```
 * @Component(...)
 * class MyComponent {
 *   constructor(@Attribute('title') title: string) { ... }
 * }
 * ```
 * When instantiated with
 * ```
 * <my-component title="Hello"></my-component>
 * ```
 *
 * Then factory method generated is:
 * ```
 * MyComponent.ɵcmp = defineComponent({
 *   factory: () => new MyComponent(injectAttribute('title'))
 *   ...
 * })
 * ```

/**
 * Creates a token that can be used in a DI Provider.
 *
 * Use an `InjectionToken` whenever the type you are injecting is not reified (does not have a
 * runtime representation) such as when injecting an interface, callable type, array or
 * parameterized type.
 *
 * `InjectionToken` is parameterized on `T` which is the type of object which will be returned by
 * the `Injector`. This provides an additional level of type safety.
 *
 * ```
 * interface MyInterface {...}
 * const myInterface = injector.get(new InjectionToken<MyInterface>('SomeToken'));
 * // myInterface is inferred to be MyInterface.
 * ```
 *
 * When creating an `InjectionToken`, you can optionally specify a factory function which returns
 * (possibly by creating) a default value of the parameterized type `T`. This sets up the
 * `InjectionToken` using this factory as a provider as if it was defined explicitly in the
 * application's root injector. If the factory function, which takes zero arguments, needs to inject
 * dependencies, it can do so using the `inject` function.
 * As you can see in the Tree-shakable InjectionToken example below.
 *
 * Additionally, if a `factory` is specified you can also specify the `providedIn` option, which
 * overrides the above behavior and marks the token as belonging to a particular `@NgModule`. As
 * mentioned above, `'root'` is the default value for `providedIn`.
 *
 * @usageNotes
 * ### Basic Examples
 *
 * ### Plain InjectionToken
 *
 * {@example core/di/ts/injector_spec.ts region='InjectionToken'}

/**
 * Injects a token from the currently active injector.
 * `inject` is only supported during instantiation of a dependency by the DI system. It can be used
 * during:
 * - Construction (via the `constructor`) of a class being instantiated by the DI system, such
 * as an `@Injectable` or `@Component`.
 * - In the initializer for fields of such classes.
 * - In the factory function specified for `useFactory` of a `Provider` or an `@Injectable`.
 * - In the `factory` function specified for an `InjectionToken`.
 *
 * @param token A token that represents a dependency that should be injected.
 * @param flags Optional flags that control how injection is executed.
 * The flags correspond to injection strategies that can be specified with
 * parameter decorators `@Host`, `@Self`, `@SkipSef`, and `@Optional`.
 * @returns the injected value if operation is successful, `null` otherwise.
 * @throws if called outside of a supported context.
 *
 * @usageNotes
 * In practice the `inject()` calls are allowed in a constructor, a constructor parameter and a
 * field initializer:
 *
 * ```typescript
 * @Injectable({providedIn: 'root'})
 * export class Car {
 *   radio: Radio|undefined;
 *   // OK: field initializer
 *   spareTyre = inject(Tyre);
 *
 *   constructor() {
 *     // OK: constructor body
 *     this.radio = inject(Radio);
 *   }
 * }
 * ```
 *
 * It is also legal to call `inject` from a provider's factory:
 *
 * ```typescript
 * providers: [
 *   {provide: Car, useFactory: () => {
 *     // OK: a class factory
 *     const engine = inject(Engine);
 *     return new Car(engine);
 *   }}
 * ]
 * ```
 *
 * Calls to the `inject()` function outside of the class creation context will result in error. Most
 * notably, calls to `inject()` are disallowed after a class instance was created, in methods
 * (including lifecycle hooks):
 *
 * ```typescript
 * @Component({ ... })
 * export class CarComponent {
 *   ngOnInit() {
 *     // ERROR: too late, the component instance was already created
 *     const engine = inject(Engine);
 *     engine.start();
 *   }
 * }
 * ```

/**
 * A ReflectiveDependency injection container used for instantiating objects and resolving
 * dependencies.
 *
 * An `Injector` is a replacement for a `new` operator, which can automatically resolve the
 * constructor dependencies.
 *
 * In typical use, application code asks for the dependencies in the constructor and they are
 * resolved by the `Injector`.
 *
 * @usageNotes
 * ### Example
 *
 * The following example creates an `Injector` configured to create `Engine` and `Car`.
 *
 * ```typescript
 * @Injectable()
 * class Engine {
 * }
 *
 * @Injectable()
 * class Car {
 *   constructor(public engine:Engine) {}
 * }
 *
 * var injector = ReflectiveInjector.resolveAndCreate([Car, Engine]);
 * var car = injector.get(Car);
 * expect(car instanceof Car).toBe(true);
 * expect(car.engine instanceof Engine).toBe(true);
 * ```
 *
 * Notice, we don't use the `new` operator because we explicitly want to have the `Injector`
 * resolve all of the object's dependencies automatically.
 *
 * TODO: delete in v14.
 *
 * @deprecated from v5 - slow and brings in a lot of code, Use `Injector.create` instead.
 * @publicApi

 * This file contains code to link styling instructions together so that they can be replayed in

 *
 * Assume we are dealing with the following code:
 * ```
 * @Component({

 *     <my-cmp [style]=" {color: '#001'} "
 *             [style.color]=" #002 "

 *     ɵɵstyleMap({color: '#003'});
 *     ɵɵstyleProp('color', '#004');
 *     ...
 *   }
 * }
 * ```
 *
 * The Order of instruction execution is:
 *
 * NOTE: the comment binding location is for illustrative purposes only.
 *
 * ```
 * // Template: (ExampleComponent)
 *     ɵɵstyleMap({color: '#001'});   // Binding index: 10
 *     ɵɵstyleProp('color', '#002');  // Binding index: 12
 * // MyComponent
 *     ɵɵstyleMap({color: '#003'});   // Binding index: 20
 *     ɵɵstyleProp('color', '#004');  // Binding index: 22
 * // Style1Directive
 *     ɵɵstyleMap({color: '#005'});   // Binding index: 24
 *     ɵɵstyleProp('color', '#006');  // Binding index: 26
 * // Style2Directive
 *     ɵɵstyleMap({color: '#007'});   // Binding index: 28
 *     ɵɵstyleProp('color', '#008');  // Binding index: 30
 * ```
 *
 * The correct priority order of concatenation is:
 *
 * ```
 * // MyComponent
 *     ɵɵstyleMap({color: '#003'});   // Binding index: 20
 *     ɵɵstyleProp('color', '#004');  // Binding index: 22
 * // Style1Directive
 *     ɵɵstyleMap({color: '#005'});   // Binding index: 24
 *     ɵɵstyleProp('color', '#006');  // Binding index: 26
 * // Style2Directive
 *     ɵɵstyleMap({color: '#007'});   // Binding index: 28
 *     ɵɵstyleProp('color', '#008');  // Binding index: 30
 * // Template: (ExampleComponent)
 *     ɵɵstyleMap({color: '#001'});   // Binding index: 10
 *     ɵɵstyleProp('color', '#002');  // Binding index: 12
 * ```
 *
 * What color should be rendered?
 *
 * Once the items are correctly sorted in the list, the answer is simply the last item in the
 * concatenation list which is `#002`.
 *
 * To do so we keep a linked list of all of the bindings which pertain to this element.
 * Notice that the bindings are inserted in the order of execution, but the `TView.data` allows
 * us to traverse them in the order of priority.
 *
 * |Idx|`TView.data`|`LView`          | Notes

 *
 * The above data structure allows us to re-concatenate the styling no matter which data binding
 * changes.
 *
 * NOTE: in addition to keeping track of next/previous index the `TView.data` also stores prev/next
 * duplicate bit. The duplicate bit if true says there either is a binding with the same name or
 * there is a map (which may contain the name). This information is useful in knowing if other
 * styles with higher priority need to be searched for overwrites.
 *
 * NOTE: See `should support example in 'tnode_linked_list.ts' documentation` in

 * 2. All `TNodeType.Placeholder` `TNodes` are elements which will be created later by

 * A [DI token](guide/glossary#di-token "DI token definition") that you can use to provide
 * one or more initialization functions.
 *
 * The provided functions are injected at application startup and executed during
 * app initialization. If any of these functions returns a Promise or an Observable, initialization
 * does not complete until the Promise is resolved or the Observable is completed.
 *
 * You can, for example, create a factory function that loads language data
 * or an external configuration, and provide that function to the `APP_INITIALIZER` token.
 * The function is executed during the application bootstrap process,
 * and the needed data is available on startup.
 *
 * @see `ApplicationInitStatus`
 *

 *

 * and a function returning a promise.

 * ```
 *  function initializeApp(): Promise<any> {

 * ```
 *
 * It's also possible to configure a multi-provider using `APP_INITIALIZER` token and a function
 * returning an observable, see an example below. Note: the `HttpClient` in this example is used for
 * demo purposes to illustrate how the factory function can work with other providers available
 * through DI.
 *
 * ```
 *  function initializeAppFactory(httpClient: HttpClient): () => Observable<any> {
 *   return () => httpClient.get("https://someUrl.com/api/user")
 *     .pipe(
 *        tap(user => { ... })

/**
 * A reference to an Angular application running on a page.
 *
 * @usageNotes
 *
 * {@a is-stable-examples}
 * ### isStable examples and caveats
 *
 * Note two important points about `isStable`, demonstrated in the examples below:
 * - the application will never be stable if you start any kind
 * of recurrent asynchronous task when the application starts
 * (for example for a polling process, started with a `setInterval`, a `setTimeout`
 * or using RxJS operators like `interval`);
 * - the `isStable` Observable runs outside of the Angular zone.
 *
 * Let's imagine that you start a recurrent task
 * (here incrementing a counter, using RxJS `interval`),
 * and at the same time subscribe to `isStable`.
 *
 * ```
 * constructor(appRef: ApplicationRef) {
 *   appRef.isStable.pipe(
 *      filter(stable => stable)
 *   ).subscribe(() => console.log('App is stable now');
 *   interval(1000).subscribe(counter => console.log(counter));
 * }
 * ```
 * In this example, `isStable` will never emit `true`,
 * and the trace "App is stable now" will never get logged.
 *
 * If you want to execute something when the app is stable,
 * you have to wait for the application to be stable
 * before starting your polling process.
 *
 * ```
 * constructor(appRef: ApplicationRef) {
 *   appRef.isStable.pipe(
 *     first(stable => stable),
 *     tap(stable => console.log('App is stable now')),
 *     switchMap(() => interval(1000))
 *   ).subscribe(counter => console.log(counter));
 * }
 * ```
 * In this example, the trace "App is stable now" will be logged
 * and then the counter starts incrementing every second.
 *
 * Note also that this Observable runs outside of the Angular zone,
 * which means that the code in the subscription
 * to this Observable will not trigger the change detection.
 *
 * Let's imagine that instead of logging the counter value,
 * you update a field of your component
 * and display it in its template.
 *
 * ```
 * constructor(appRef: ApplicationRef) {
 *   appRef.isStable.pipe(
 *     first(stable => stable),
 *     switchMap(() => interval(1000))
 *   ).subscribe(counter => this.value = counter);
 * }
 * ```
 * As the `isStable` Observable runs outside the zone,
 * the `value` field will be updated properly,
 * but the template will not be refreshed!
 *
 * You'll have to manually trigger the change detection to update the template.
 *
 * ```
 * constructor(appRef: ApplicationRef, cd: ChangeDetectorRef) {
 *   appRef.isStable.pipe(
 *     first(stable => stable),
 *     switchMap(() => interval(1000))
 *   ).subscribe(counter => {
 *     this.value = counter;
 *     cd.detectChanges();
 *   });
 * }
 * ```
 *
 * Or make the subscription callback run inside the zone.
 *
 * ```
 * constructor(appRef: ApplicationRef, zone: NgZone) {
 *   appRef.isStable.pipe(
 *     first(stable => stable),
 *     switchMap(() => interval(1000))
 *   ).subscribe(counter => zone.run(() => this.value = counter));
 * }
 * ```

   * Bootstrap a component onto the element identified by its selector or, optionally, to a
   * specified element.
   *
   * @usageNotes
   * ### Bootstrap process
   *
   * When bootstrapping a component, Angular mounts it onto a target DOM element
   * and kicks off automatic change detection. The target DOM element can be
   * provided using the `rootSelectorOrNode` argument.
   *
   * If the target DOM element is not provided, Angular tries to find one on a page
   * using the `selector` of the component that is being bootstrapped
   * (first matched element is used).
   *
   * ### Example
   *
   * Generally, we define the component to bootstrap in the `bootstrap` array of `NgModule`,
   * but it requires us to know the component while writing the application code.
   *
   * Imagine a situation where we have to wait for an API call to decide about the component to
   * bootstrap. We can use the `ngDoBootstrap` hook of the `NgModule` and call this method to
   * dynamically bootstrap a component.
   *
   * {@example core/ts/platform/platform.ts region='componentSelector'}
   *
   * Optionally, a component can be mounted onto a DOM element that does not match the
   * selector of the bootstrapped component.
   *
   * In the following example, we are providing a CSS selector to match the target element.
   *
   * {@example core/ts/platform/platform.ts region='cssSelector'}
   *
   * While in this example, we are providing reference to a DOM node.
   *
   * {@example core/ts/platform/platform.ts region='domNode'}

 *
 * ### Detach change detector to limit how often check occurs
 *
 * The following example defines a component with a large list of read-only data

 * ### Reattaching a detached component
 *
 * The following example creates a component displaying live data.
 * The component detaches its change detector from the main change detector tree
 * when the `live` property is set to false, and reattaches it when the property
 * becomes true.

 * so that it gets included into change detection cycles.
 *
 * Note: the example uses standalone components, but the function can also be used for
 * non-standalone components (declared in an NgModule) as well.
 *
 * ```typescript
 * @Component({
 *   standalone: true,
 *   template: `Hello {{ name }}!`
 * })
 * class HelloComponent {
 *   name = 'Angular';
 * }
 *
 * @Component({

 *   template: `<div id="hello-component-host"></div>`
 * })
 * class RootComponent {}
 *
 * // Bootstrap an application.
 * const applicationRef = await bootstrapApplication(RootComponent);
 *
 * // Locate a DOM node that would be used as a host.
 * const host = document.getElementById('hello-component-host');
 *
 * // Get an `EnvironmentInjector` instance from the `ApplicationRef`.
 * const environmentInjector = applicationRef.injector;
 *
 * // We can now create a `ComponentRef` instance.
 * const componentRef = createComponent(HelloComponent, {host, environmentInjector});
 *
 * // Last step is to register the newly created ref using the `ApplicationRef` instance
 * // to include the component view into change detection cycles.
 * applicationRef.attachView(componentRef.hostView);
 * ```
 *
 * @param component Component class reference.
 * @param options Set of options to use:
 *  * `environmentInjector`: An `EnvironmentInjector` instance to be used for the component, see
 * additional info about it at https://angular.io/guide/standalone-components#environment-injectors.
 *  * `hostElement` (optional): A DOM node that should act as a host node for the component. If not
 * provided, Angular creates one based on the tag name used in the component selector (and falls
 * back to using `div` if selector doesn't have tag name info).
 *  * `elementInjector` (optional): An `ElementInjector` instance, see additional info about it at
 * https://angular.io/guide/hierarchical-dependency-injection#elementinjector.
 *  * `projectableNodes` (optional): A list of DOM nodes that should be projected through
 *                      [`<ng-content>`](api/core/ng-content) of the new component instance.

 *   punctuation symbols).
 * - `local-part` cannot begin or end with a period (`.`).
 * - `local-part` cannot be longer than 64 characters.
 * - `tld` consists of one or more `labels` separated by periods (`.`). For example `localhost` or

 * - A `label` consists of one or more of the allowed characters (alphanumeric, dashes (`-`) and

 * - A `label` cannot be longer than 63 characters.
 * - The whole address cannot be longer than 254 characters.
 *
 * ## Implementation background
 *
 * This regexp was ported over from AngularJS (see there for git history):
 * https://github.com/angular/angular.js/blob/c133ef836/src/ng/directive/input.js#L27
 * It is based on the
 * [WHATWG version](https://html.spec.whatwg.org/multipage/input.html#valid-e-mail-address) with
 * some enhancements to incorporate more RFC rules (such as rules related to domain names and the
 * lengths of different parts of the address). The main differences from the WHATWG version are:
 *   - Disallow `local-part` to begin or end with a period (`.`).
 *   - Disallow `local-part` length to exceed 64 characters.
 *   - Disallow total address length to exceed 254 characters.
 *
 * See [this commit](https://github.com/angular/angular.js/commit/f3f5cf72e) for more details.

   * (`RegExp` preserves the index of the last match when the global or sticky flag is used).
   * Due to this behavior, it is recommended that when using
   * `Validators.pattern` you **do not** pass in a `RegExp` object with either the global or sticky
   * flag enabled.
   *
   * ```typescript
   * // Not recommended (since the `g` flag is used)
   * const controlOne = new FormControl('1', Validators.pattern(/foo/g));
   *
   * // Good
   * const controlTwo = new FormControl('1', Validators.pattern(/foo/));
   * ```
   *
   * @param pattern A regular expression to be used as is to test the values, or a string.
   * If a string is passed, the `^` character is prepended and the `$` character is
   * appended to the provided string (if not already present), and the resulting regular
   * expression is used to test the values.

/**
 * Tracks the value and validity state of a group of `FormControl` instances.
 *
 * A `FormGroup` aggregates the values of each child `FormControl` into one object,
 * with each control name as the key.  It calculates its status by reducing the status values
 * of its children. For example, if one of the controls in a group is invalid, the entire
 * group becomes invalid.
 *
 * `FormGroup` is one of the four fundamental building blocks used to define forms in Angular,
 * along with `FormControl`, `FormArray`, and `FormRecord`.
 *
 * When instantiating a `FormGroup`, pass in a collection of child controls as the first
 * argument. The key for each child registers the name for the control.
 *
 * `FormGroup` is intended for use cases where the keys are known ahead of time.
 * If you need to dynamically add and remove controls, use {@link FormRecord} instead.
 *
 * `FormGroup` accepts an optional type parameter `TControl`, which is an object type with inner
 * control types as values.
 *

 * const form = new FormGroup({
 *   first: new FormControl('Nancy', Validators.minLength(2)),
 *   last: new FormControl('Drew'),
 * });
 *
 * console.log(form.value);   // {first: 'Nancy', last; 'Drew'}
 * console.log(form.status);  // 'VALID'
 * ```
 *
 * ### The type argument, and optional controls
 *
 * `FormGroup` accepts one generic argument, which is an object containing its inner controls.
 * This type will usually be inferred automatically, but you can always specify it explicitly if you
 * wish.
 *
 * If you have controls that are optional (i.e. they can be removed, you can use the `?` in the
 * type):
 *
 * ```
 * const form = new FormGroup<{
 *   first: FormControl<string|null>,
 *   middle?: FormControl<string|null>, // Middle name is optional.
 *   last: FormControl<string|null>,
 * }>({
 *   first: new FormControl('Nancy'),
 *   last: new FormControl('Drew'),
 * });
 * ```
 *
 * ### Create a form group with a group-level validator
 *
 * You include group-level validators as the second arg, or group-level async
 * validators as the third arg. These come in handy when you want to perform validation
 * that considers the value of more than one child control.
 *
 * ```
 * const form = new FormGroup({
 *   password: new FormControl('', Validators.minLength(2)),
 *   passwordConfirm: new FormControl('', Validators.minLength(2)),
 * }, passwordMatchValidator);
 *
 *
 * function passwordMatchValidator(g: FormGroup) {
 *    return g.get('password').value === g.get('passwordConfirm').value
 *       ? null : {'mismatch': true};
 * }
 * ```
 *
 * Like `FormControl` instances, you choose to pass in
 * validators and async validators as part of an options object.
 *
 * ```
 * const form = new FormGroup({
 *   password: new FormControl('')
 *   passwordConfirm: new FormControl('')
 * }, { validators: passwordMatchValidator, asyncValidators: otherValidator });
 * ```
 *
 * ### Set the updateOn property for all controls in a form group
 *
 * The options object is used to set a default value for each child
 * control's `updateOn` property. If you set `updateOn` to `'blur'` at the
 * group level, all child controls default to 'blur', unless the child
 * has explicitly specified a different `updateOn` value.
 *
 * ```ts
 * const c = new FormGroup({
 *   one: new FormControl()
 * }, { updateOn: 'blur' });
 * ```
 *
 * ### Using a FormGroup with optional controls
 *
 * It is possible to have optional controls in a FormGroup. An optional control can be removed later
 * using `removeControl`, and can be omitted when calling `reset`. Optional controls must be
 * declared optional in the group's type.
 *
 * ```ts
 * const c = new FormGroup<{one?: FormControl<string>}>({
 *   one: new FormControl('')
 * });
 * ```
 *
 * Notice that `c.value.one` has type `string|null|undefined`. This is because calling `c.reset({})`
 * without providing the optional key `one` will cause it to become `null`.

/**
 * @description
 * Creates a top-level `FormGroup` instance and binds it to a form
 * to track aggregate form value and validation status.
 *
 * As soon as you import the `FormsModule`, this directive becomes active by default on
 * all `<form>` tags.  You don't need to add a special selector.
 *
 * You optionally export the directive into a local template variable using `ngForm` as the key
 * (ex: `#myForm="ngForm"`). This is optional, but useful.  Many properties from the underlying
 * `FormGroup` instance are duplicated on the directive itself, so a reference to it
 * gives you access to the aggregate value and validity status of the form, as well as
 * user interaction properties like `dirty` and `touched`.
 *
 * To register child controls with the form, use `NgModel` with a `name`
 * attribute. You may use `NgModelGroup` to create sub-groups within the form.
 *
 * If necessary, listen to the directive's `ngSubmit` event to be notified when the user has
 * triggered a form submission. The `ngSubmit` event emits the original form
 * submission event.
 *
 * In template driven forms, all `<form>` tags are automatically tagged as `NgForm`.
 * To import the `FormsModule` but skip its usage in some forms,
 * for example, to use native HTML5 validation, add the `ngNoForm` and the `<form>`
 * tags won't create an `NgForm` directive. In reactive forms, using `ngNoForm` is
 * unnecessary because the `<form>` tags are inert. In that case, you would
 * refrain from using the `formGroup` directive.
 *
 * @usageNotes
 *
 * ### Listening for form submission
 *
 * The following example shows how to capture the form values from the "ngSubmit" event.
 *
 * {@example forms/ts/simpleForm/simple_form_example.ts region='Component'}
 *
 * ### Setting the update options
 *
 * The following example shows you how to change the "updateOn" option from its default using
 * ngFormOptions.
 *
 * ```html
 * <form [ngFormOptions]="{updateOn: 'blur'}">
 *    <input name="one" ngModel>  <!-- this ngModel will update on blur -->
 * </form>
 * ```
 *
 * ### Native DOM validation UI
 *
 * In order to prevent the native DOM form validation UI from interfering with Angular's form
 * validation, Angular automatically adds the `novalidate` attribute on any `<form>` whenever
 * `FormModule` or `ReactiveFormModule` are imported into the application.
 * If you want to explicitly enable native DOM validation UI with Angular forms, you can add the
 * `ngNativeValidate` attribute to the `<form>` element:
 *
 * ```html
 * <form ngNativeValidate>
 *   ...
 * </form>
 * ```
 *
 * @ngModule FormsModule

 * I.e. `ngModel` can export itself on the element and then be used in the template.

 * to have an old value as they have been
 * dirty checked before. As this is a very common case for `ngModel`, we added this second change

const resolvedPromise = (() => Promise.resolve())();
/**
 * @description
 * Creates a `FormControl` instance from a domain model and binds it
 * to a form control element.
 *
 * The `FormControl` instance tracks the value, user interaction, and
 * validation status of the control and keeps the view synced with the model. If used
 * within a parent form, the directive also registers itself with the form as a child
 * control.
 *
 * This directive is used by itself or as part of a larger form. Use the
 * `ngModel` selector to activate it.
 *
 * It accepts a domain model as an optional `Input`. If you have a one-way binding
 * to `ngModel` with `[]` syntax, changing the domain model's value in the component
 * class sets the value in the view. If you have a two-way binding with `[()]` syntax
 * (also known as 'banana-in-a-box syntax'), the value in the UI always syncs back to
 * the domain model in your class.
 *
 * To inspect the properties of the associated `FormControl` (like the validity state),
 * export the directive into a local template variable using `ngModel` as the key (ex:
 * `#myVar="ngModel"`). You can then access the control using the directive's `control` property.
 * However, the most commonly used properties (like `valid` and `dirty`) also exist on the control
 * for direct access. See a full list of properties directly available in
 * `AbstractControlDirective`.
 *
 * @see `RadioControlValueAccessor`
 * @see `SelectControlValueAccessor`
 *
 * @usageNotes
 *
 * ### Using ngModel on a standalone control
 *
 * The following examples show a simple standalone control using `ngModel`:
 *
 * {@example forms/ts/simpleNgModel/simple_ng_model_example.ts region='Component'}
 *
 * When using the `ngModel` within `<form>` tags, you'll also need to supply a `name` attribute
 * so that the control can be registered with the parent form under that name.
 *
 * In the context of a parent form, it's often unnecessary to include one-way or two-way binding,
 * as the parent form syncs the value for you. You access its properties by exporting it into a
 * local template variable using `ngForm` such as (`#f="ngForm"`). Use the variable where
 * needed on form submission.
 *
 * If you do need to populate initial values into your form, using a one-way binding for
 * `ngModel` tends to be sufficient as long as you use the exported form's value rather
 * than the domain model's value on submit.
 *
 * ### Using ngModel within a form
 *
 * The following example shows controls using `ngModel` within a form:
 *
 * {@example forms/ts/simpleForm/simple_form_example.ts region='Component'}
 *
 * ### Using a standalone ngModel within a group
 *
 * The following example shows you how to use a standalone ngModel control
 * within a form. This controls the display of the form, but doesn't contain form data.
 *
 * ```html
 * <form>
 *   <input name="login" ngModel placeholder="Login">
 *   <input type="checkbox" ngModel [ngModelOptions]="{standalone: true}"> Show more options?
 * </form>
 * <!-- form value: {login: ''} -->
 * ```
 *
 * ### Setting the ngModel `name` attribute through options
 *
 * The following example shows you an alternate way to set the name attribute. Here,
 * an attribute identified as name is used within a custom form control component. To still be able
 * to specify the NgModel's name, you must specify it using the `ngModelOptions` input instead.
 *
 * ```html
 * <form>
 *   <my-custom-form-control name="Nancy" ngModel [ngModelOptions]="{name: 'user'}">
 *   </my-custom-form-control>
 * </form>
 * <!-- form value: {user: ''} -->
 * ```

/**
 * @description
 * The `ControlValueAccessor` for writing select control values and listening to select control
 * changes. The value accessor is used by the `FormControlDirective`, `FormControlName`, and
 * `NgModel` directives.
 *
 * @usageNotes
 *
 * ### Using select controls in a reactive form
 *
 * The following examples show how to use a select control in a reactive form.
 *
 * {@example forms/ts/reactiveSelectControl/reactive_select_control_example.ts region='Component'}
 *
 * ### Using select controls in a template-driven form
 *
 * To use a select in a template-driven form, simply add an `ngModel` and a `name`
 * attribute to the main `<select>` tag.
 *
 * {@example forms/ts/selectControl/select_control_example.ts region='Component'}
 *
 * ### Customizing option selection
 *
 * Angular uses object identity to select option. It's possible for the identities of items
 * to change while the data does not. This can happen, for example, if the items are produced
 * from an RPC to the server, and that RPC is re-run. Even if the data hasn't changed, the
 * second response will produce objects with different identities.
 *
 * To customize the default option comparison algorithm, `<select>` supports `compareWith` input.
 * `compareWith` takes a **function** which has two arguments: `option1` and `option2`.
 * If `compareWith` is given, Angular selects option by the return value of the function.
 *
 * ```ts
 * const selectedCountriesControl = new FormControl();
 * ```
 *
 * ```
 * <select [compareWith]="compareFn"  [formControl]="selectedCountriesControl">
 *     <option *ngFor="let country of countries" [ngValue]="country">
 *         {{country.name}}
 *     </option>
 * </select>
 *
 * compareFn(c1: Country, c2: Country): boolean {
 *     return c1 && c2 ? c1.id === c2.id : c1 === c2;
 * }
 * ```
 *
 * **Note:** We listen to the 'change' event because 'input' events aren't fired
 * for selects in IE, see:
 * https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/input_event#browser_compatibility
 *
 * @ngModule ReactiveFormsModule
 * @ngModule FormsModule

/**
 * Tracks the value and validity state of an array of `FormControl`,
 * `FormGroup` or `FormArray` instances.
 *
 * A `FormArray` aggregates the values of each child `FormControl` into an array.
 * It calculates its status by reducing the status values of its children. For example, if one of
 * the controls in a `FormArray` is invalid, the entire array becomes invalid.
 *
 * `FormArray` accepts one generic argument, which is the type of the controls inside.
 * If you need a heterogenous array, use {@link UntypedFormArray}.
 *
 * `FormArray` is one of the four fundamental building blocks used to define forms in Angular,
 * along with `FormControl`, `FormGroup`, and `FormRecord`.
 *
 * @usageNotes
 *
 * ### Create an array of form controls
 *
 * ```
 * const arr = new FormArray([
 *   new FormControl('Nancy', Validators.minLength(2)),
 *   new FormControl('Drew'),
 * ]);
 *
 * console.log(arr.value);   // ['Nancy', 'Drew']
 * console.log(arr.status);  // 'VALID'
 * ```
 *
 * ### Create a form array with array-level validators
 *
 * You include array-level validators and async validators. These come in handy
 * when you want to perform validation that considers the value of more than one child
 * control.
 *
 * The two types of validators are passed in separately as the second and third arg
 * respectively, or together as part of an options object.
 *
 * ```
 * const arr = new FormArray([
 *   new FormControl('Nancy'),
 *   new FormControl('Drew')
 * ], {validators: myValidator, asyncValidators: myAsyncValidator});
 * ```
 *
 * ### Set the updateOn property for all controls in a form array
 *
 * The options object is used to set a default value for each child
 * control's `updateOn` property. If you set `updateOn` to `'blur'` at the
 * array level, all child controls default to 'blur', unless the child
 * has explicitly specified a different `updateOn` value.
 *
 * ```ts
 * const arr = new FormArray([
 *    new FormControl()
 * ], {updateOn: 'blur'});
 * ```
 *
 * ### Adding or removing controls from a form array
 *
 * To change the controls in the array, use the `push`, `insert`, `removeAt` or `clear` methods
 * in `FormArray` itself. These methods ensure the controls are properly tracked in the
 * form's hierarchy. Do not modify the array of `AbstractControl`s used to instantiate
 * the `FormArray` directly, as that result in strange and unexpected behavior such
 * as broken change detection.
 *

// The option group has two different "modes": regular and inert. The regular mode uses the
// recommended a11y pattern which has `role="group"` on the group element with `aria-labelledby`
// pointing to the label. This works for `mat-select`, but it seems to hit a bug for autocomplete
// under VoiceOver where the group doesn't get read out at all. The bug appears to be that if
// there's __any__ a11y-related attribute on the group (e.g. `role` or `aria-labelledby`),
// VoiceOver on Safari won't read it out.
// We've introduced the `inert` mode as a workaround. Under this mode, all a11y attributes are
// removed from the group, and we get the screen reader to read out the group label by mirroring it
// inside an invisible element in the option. This is sub-optimal, because the screen reader will
// repeat the group label on each navigation, whereas the default pattern only reads the group when
// the user enters a new group. The following alternate approaches were considered:
// 1. Reading out the group label using the `LiveAnnouncer` solves the problem, but we can't control
//    when the text will be read out so sometimes it comes in too late or never if the user
//    navigates quickly.
// 2. `<mat-option aria-describedby="groupLabel"` - This works on Safari, but VoiceOver in Chrome
//    won't read out the description at all.
// 3. `<mat-option aria-labelledby="optionLabel groupLabel"` - This works on Chrome, but Safari
//     doesn't read out the text at all. Furthermore, on
// Boilerplate for applying mixins to MatOptgroup.

 * Component to display an icon. It can be used in the following ways:
 *
 * - Specify the svgIcon input to load an SVG icon from a URL previously registered with the
 *   addSvgIcon, addSvgIconInNamespace, addSvgIconSet, or addSvgIconSetInNamespace methods of
 *   MatIconRegistry. If the svgIcon value contains a colon it is assumed to be in the format
 *   "[namespace]:[name]", if not the value will be the name of an icon in the default namespace.
 *   Examples:
 *     `<mat-icon svgIcon="left-arrow"></mat-icon>
 *     <mat-icon svgIcon="animals:cat"></mat-icon>`
 *
 * - Use a font ligature as an icon by putting the ligature text in the content of the `<mat-icon>`
 *   component. By default the Material icons font is used as described at
 *   http://google.github.io/material-design-icons/#icon-font-for-the-web. You can specify an
 *   alternate font by setting the fontSet input to either the CSS class to apply to use the
 *   desired font, or to an alias previously registered with MatIconRegistry.registerFontClassAlias.
 *   Examples:
 *     `<mat-icon>home</mat-icon>
 *     <mat-icon fontSet="myfont">sun</mat-icon>`
 *
 * - Specify a font glyph to be included via CSS rules by setting the fontSet input to specify the
 *   font, and the fontIcon input to specify the icon. Typically the fontIcon will specify a
 *   CSS class which causes the glyph to be displayed via a :before selector, as in
 *   https://fortawesome.github.io/Font-Awesome/examples/
 *   Example:
 *     `<mat-icon fontSet="fa" fontIcon="alarm"></mat-icon>`

/**
 * DomSanitizer helps preventing Cross Site Scripting Security bugs (XSS) by sanitizing
 * values to be safe to use in the different DOM contexts.
 *
 * For example, when binding a URL in an `<a [href]="someValue">` hyperlink, `someValue` will be
 * sanitized so that an attacker cannot inject e.g. a `javascript:` URL that would execute code on
 * the website.
 *
 * In specific situations, it might be necessary to disable sanitization, for example if the
 * application genuinely needs to produce a `javascript:` style link with a dynamic value in it.
 * Users can bypass security by constructing a value with one of the `bypassSecurityTrust...`
 * methods, and then binding to that value from the template.
 *
 * These situations should be very rare, and extraordinary care must be taken to avoid creating a
 * Cross Site Scripting (XSS) security bug!
 *
 * When using `bypassSecurityTrust...`, make sure to call the method as early as possible and as
 * close as possible to the source of the value, to make it easy to verify no security bug is
 * created by its use.
 *
 * It is not required (and not recommended) to bypass security if the value is safe, e.g. a URL that
 * does not start with a suspicious protocol, or an HTML snippet that does not contain dangerous
 * code. The sanitizer leaves safe values intact.
 *
 * @security Calling any of the `bypassSecurityTrust...` APIs disables Angular's built-in
 * sanitization for the value passed in. Carefully check and audit all values and code paths going
 * into this call. Make sure any user data is appropriately escaped for this security context.

 * Acts as a placeholder that Angular dynamically fills based on the current router state.

 * The name cannot be set or changed dynamically. If not set, default value is "primary".
 *
 * ```
 * <router-outlet></router-outlet>
 * <router-outlet name='left'></router-outlet>
 * <router-outlet name='right'></router-outlet>
 * ```
 *
 * Named outlets can be the targets of secondary routes.
 * The `Route` object for a secondary route has an `outlet` property to identify the target outlet:
 *
 * `{path: <base-path>, component: <component>, outlet: <target_outlet_name>}`
 *
 * Using named outlets and secondary routes, you can target multiple outlets in
 * the same `RouterLink` directive.
 *
 * The router keeps track of separate branches in a navigation tree for each named outlet and
 * generates a representation of that tree in the URL.
 * The URL for a secondary route uses the following syntax to specify both the primary and secondary
 * routes at the same time:
 *
 * `http://base-path/primary-route-path(outlet-name:route-path)`
 *
 * A router outlet emits an activate event when a new component is instantiated,
 * deactivate event when a component is destroyed.
 * An attached event emits when the `RouteReuseStrategy` instructs the outlet to reattach the
 * subtree, and the detached event emits when the `RouteReuseStrategy` instructs the outlet to
 * detach the subtree.

 * in one or more `<router-outlet>` locations on the page.
 *
 * Given a route configuration `[{ path: 'user/:name', component: UserCmp }]`,
 * the following creates a static link to the route:
 * `<a routerLink="/user/bob">link to user component</a>`
 *
 * You can use dynamic values to generate the link.
 * For a dynamic link, pass an array of path segments,
 * followed by the params for each segment.
 * For example, `['/team', teamId, 'user', userName, {details: true}]`
 * generates a link to `/team/11/user/bob;details=true`.
 *
 * Multiple static segments can be merged into one term and combined with dynamic segments.
 * For example, `['/team/11/user', userName, {details: true}]`
 *
 * The input that you provide to the link is treated as a delta to the current URL.
 * For instance, suppose the current URL is `/user/(box//aux:team)`.
 * The link `<a [routerLink]="['/user/jim']">Jim</a>` creates the URL
 * `/user/(jim//aux:team)`.
 * See {@link Router#createUrlTree createUrlTree} for more information.
 *
 * @usageNotes
 *
 * You can use absolute or relative paths in a link, set query parameters,
 * control how parameters are handled, and keep a history of navigation states.
 *
 * ### Relative link paths
 *
 * The first segment name can be prepended with `/`, `./`, or `../`.
 * * If the first segment begins with `/`, the router looks up the route from the root of the
 *   app.
 * * If the first segment begins with `./`, or doesn't begin with a slash, the router
 *   looks in the children of the current activated route.
 * * If the first segment begins with `../`, the router goes up one level in the route tree.
 *
 * ### Setting and handling query params and fragments
 *
 * The following link adds a query parameter and a fragment to the generated URL:
 *
 * ```
 * <a [routerLink]="['/user/bob']" [queryParams]="{debug: true}" fragment="education">
 *   link to user component
 * </a>
 * ```
 * By default, the directive constructs the new URL using the given query parameters.
 * The example generates the link: `/user/bob?debug=true#education`.
 *
 * You can instruct the directive to handle query parameters differently
 * by specifying the `queryParamsHandling` option in the link.
 * Allowed values are:
 *
 *  - `'merge'`: Merge the given `queryParams` into the current query params.
 *  - `'preserve'`: Preserve the current query params.
 *
 * For example:
 *
 * ```
 * <a [routerLink]="['/user/bob']" [queryParams]="{debug: true}" queryParamsHandling="merge">
 *   link to user component
 * </a>
 * ```
 *
 * See {@link UrlCreationOptions.queryParamsHandling UrlCreationOptions#queryParamsHandling}.
 *
 * ### Preserving navigation history
 *
 * You can provide a `state` value to be persisted to the browser's
 * [`History.state` property](https://developer.mozilla.org/en-US/docs/Web/API/History#Properties).
 * For example:
 *
 * ```
 * <a [routerLink]="['/user/bob']" [state]="{tracingId: 123}">
 *   link to user component
 * </a>
 * ```
 *
 * Use {@link Router.getCurrentNavigation() Router#getCurrentNavigation} to retrieve a saved
 * navigation-state value. For example, to capture the `tracingId` during the `NavigationStart`
 * event:
 *
 * ```
 * // Get NavigationStart events
 * router.events.pipe(filter(e => e instanceof NavigationStart)).subscribe(e => {
 *   const navigation = router.getCurrentNavigation();
 *   tracingService.trace({id: navigation.extras.state.tracingId});
 * });
 * ```
 *

/**
 *
 * @description
 *
 * Tracks whether the linked route of an element is currently active, and allows you
 * to specify one or more CSS classes to add to the element when the linked route
 * is active.
 *
 * Use this directive to create a visual distinction for elements associated with an active route.
 * For example, the following code highlights the word "Bob" when the router
 * activates the associated route:
 *
 * ```
 * <a routerLink="/user/bob" routerLinkActive="active-link">Bob</a>
 * ```
 *
 * Whenever the URL is either '/user' or '/user/bob', the "active-link" class is
 * added to the anchor tag. If the URL changes, the class is removed.
 *
 * You can set more than one class using a space-separated string or an array.
 * For example:
 *
 * ```
 * <a routerLink="/user/bob" routerLinkActive="class1 class2">Bob</a>
 * <a routerLink="/user/bob" [routerLinkActive]="['class1', 'class2']">Bob</a>
 * ```
 *
 * To add the classes only when the URL matches the link exactly, add the option `exact: true`:
 *
 * ```
 * <a routerLink="/user/bob" routerLinkActive="active-link" [routerLinkActiveOptions]="{exact:
 * true}">Bob</a>
 * ```
 *
 * To directly check the `isActive` status of the link, assign the `RouterLinkActive`
 * instance to a template variable.
 * For example, the following checks the status without assigning any CSS classes:
 *
 * ```
 * <a routerLink="/user/bob" routerLinkActive #rla="routerLinkActive">
 *   Bob {{ rla.isActive ? '(already open)' : ''}}
 * </a>
 * ```
 *
 * You can apply the `RouterLinkActive` directive to an ancestor of linked elements.
 * For example, the following sets the active-link class on the `<div>`  parent tag
 * when the URL is either '/user/jim' or '/user/bob'.
 *
 * ```
 * <div routerLinkActive="active-link" [routerLinkActiveOptions]="{exact: true}">
 *   <a routerLink="/user/jim">Jim</a>
 *   <a routerLink="/user/bob">Bob</a>
 * </div>
 * ```
 *
 * The `RouterLinkActive` directive can also be used to set the aria-current attribute
 * to provide an alternative distinction for active elements to visually impaired users.
 *
 * For example, the following code adds the 'active' class to the Home Page link when it is
 * indeed active and in such case also sets its aria-current attribute to 'page':
 *
 * ```
 * <a routerLink="/" routerLinkActive="active" ariaCurrentWhenActive="page">Home Page</a>
 * ```
