|  * | |
|  * 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. | |
|  * | |
|  * {@example common/pipes/ts/async_pipe.ts region='AsyncPipeObservable'} | |

|  * | |
|  * 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. | |
|  * | |
|  * @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. | |

|  * ### 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`: | |
|  * 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 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). | |
|  * | |
|  * ### Example | |
|  * | |
|  * The following code shows how the pipe transforms values | |

|  * | |
|  * A service that applications can use to interact with a browser's URL. | |
|  * | |
|  * Depending on the `LocationStrategy` used, `Location` persists | |
|  * to the URL's path or the URL's hash segment. | |
|  * | |
|  * @usageNotes | |
|  * | |
|  * It's better to use the `Router.navigate()` service to trigger route changes. Use | |
|  * `Location` only if you need to interact with or create normalized URLs outside of | |
|  * routing. | |
|  * | |
|  * `Location` is responsible for normalizing the URL against the application's base href. | |
|  * A normalized URL is absolute from the URL host, includes the application's base href, and has no | |
|  * trailing slash: | |
|  * - `/my/app/user/123` is normalized | |
|  * - `my/app/user/123` **is not** normalized | |

|  * the Component. Defaults to the injector of the current view container. | |

|  * ### Syntax | |
|  * | |
|  * Simple | |
|  * ``` | |
|  * <ng-container *ngComponentOutlet="componentTypeExpression"></ng-container> | |
|  * ``` | |
|  * | |
|  * Customized injector/content | |
|  * ``` | |
|  * <ng-container *ngComponentOutlet="componentTypeExpression; | |
|  *                                   injector: injectorExpression; | |
|  *                                   content: contentNodesExpression;"> | |
|  * </ng-container> | |
|  * ``` | |
|  * | |
|  * Customized ngModuleFactory | |
|  * ``` | |
|  * <ng-container *ngComponentOutlet="componentTypeExpression; | |

| /** | |
|  * 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/built-in-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 futher discussion, see | |
|  * [Structural Directives](guide/built-in-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: | |

|  * true.</div></ng-template> | |
|  * ``` | |
|  * | |
|  * Form with an "else" block: | |
|  * | |
|  * ``` | |
|  * <div *ngIf="condition; else elseBlock">Content to render when condition is true.</div> | |
|  * <ng-template #elseBlock>Content to render when condition is false.</ng-template> | |
|  * ``` | |
|  * | |
|  * Shorthand form with "then" and "else" blocks: | |
|  * | |
|  * ``` | |
|  * <div *ngIf="condition; then thenBlock else elseBlock"></div> | |
|  * <ng-template #thenBlock>Content to render when condition is true.</ng-template> | |
|  * <ng-template #elseBlock>Content to render when condition is false.</ng-template> | |
|  * ``` | |

|  * ``` | |
|  * <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](https://angular.io/guide/built-in-directives#one-per-element). | |

|  * 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 | |

|  * | |
|  * ``` | |
|  * <container-element [ngSwitch]="switch_expression"> | |

|  * <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"> | |
