The context\n * for each instantiated template inherits from the outer context with the given loop variable\n * set to the current item from the iterable.\n *\n * @usageNotes\n *\n * ### Local Variables\n *\n * `NgForOf` provides several exported values that can be aliased to local variables:\n *\n * - `$implicit: T`: The value of the individual items in the iterable (`ngForOf`).\n * - `ngForOf: NgIterable<T>`: The value of the iterable expression. Useful when the expression is\n * more complex then a property access, for example when using the async pipe (`userStreams |\n * async`).\n * - `index: number`: The index of the current item in the iterable.\n * - `first: boolean`: True when the item is the first item in the iterable.\n * - `last: boolean`: True when the item is the last item in the iterable.\n * - `even: boolean`: True when the item has an even index in the iterable.\n * - `odd: boolean`: True when the item has an odd index in the iterable.\n *\n * ```\n * <li *ngFor=\"let user of userObservable | async as users; index as i; first as isFirst\">\n *    {{i}}/{{users.length}}. {{user}} <span *ngIf=\"isFirst\">default</span>\n * </li>\n * ```\n *\n * ### Change Propagation\n *\n * When the contents of the iterator changes, `NgForOf` makes the corresponding changes to the DOM:\n *\n * * When an item is added, a new instance of the template is added to the DOM.\n * * When an item is removed, its template instance is removed from the DOM.\n * * When items are reordered, their respective templates are reordered in the DOM.\n * * Otherwise, the DOM element for that item will remain the same.\n *\n * Angular uses object identity to track insertions and deletions within the iterator and reproduce\n * those changes in the DOM. This has important implications for animations and any stateful\n * controls (such as `<input>` elements which accept user input) that are present. Inserted rows can\n * be animated in, deleted rows can be animated out, and unchanged rows retain any unsaved state\n * such as user input.\n *\n * It is possible for the identities of elements in the iterator to change while the data does not.\n * This can happen, for example, if the iterator produced from an RPC to the server, and that\n * RPC is re-run.

Typically the:\n *  - `then` template is the inline template of `ngIf` unless bound to a different value.\n *  - `else` template is blank unless it is bound.\n *\n *\n * @usageNotes\n *\n * ### Most common usage\n *\n * The most common usage of the `ngIf` directive is to conditionally show the inline template as\n * seen in this example:\n * {@example common/ngIf/ts/module.ts region='NgIfSimple'}\n *\n * ### Showing an alternative template using `else`\n *\n * If it is necessary to display a template when the `expression` is falsy use the `else` template\n * binding as shown. Note that the `else` binding points to a `<ng-template>` labeled `#elseBlock`.\n * The template can be defined anywhere in the component view but is typically placed right after\n * `ngIf` for readability.\n *\n * {@example common/ngIf/ts/module.ts region='NgIfElse'}\n *\n * ### Using non-inlined `then` template\n *\n * Usually the `then` template is the inlined template of the `ngIf`, but it can be changed using\n * a binding (just like `else`). Because `then` and `else` are bindings, the template references can\n * change at runtime as shown in this example.\n *\n * {@example common/ngIf/ts/module.ts region='NgIfThenElse'}\n *\n * ### Storing conditional result in a variable\n *\n * A common pattern is that we need to show a set of properties from the same object. If the\n * object is undefined, then we have to use the safe-traversal-operator `?.` to guard against\n * dereferencing a `null` value. This is especially the case when waiting on async data such as\n * when using the `async` pipe as shown in following example:\n *\n * ```\n * Hello {{ (userStream|async)?.last }}, {{ (userStream|async)?.first }}!\n * ```\n *\n * There are several inefficiencies in the above example:\n *  - We create multiple subscriptions on `userStream`. One for each `async` pipe, or two in the\n *    example above.\n *  - We cannot display an alternative screen while waiting for the data to arrive asynchronously.\n *  - We have to use the safe-traversal-operator `?.` to access properties, which is cumbersome.\n *  - We have to place the `async` pipe in parenthesis.\n *\n * A better way to do this is to use `ngIf` and store the result of the condition in a local\n * variable as shown in the the example below:\n *\n * {@example common/ngIf/ts/module.ts region='NgIfAs'}\n *\n * Notice that:\n *  - We use only one `async` pipe and hence only one subscription gets created.\n *  - `ngIf` stores the result of the `userStream|async` in the local variable `user`.\n *  - The local `user` can then be bound repeatedly in a more efficient way.\n *  - No need to use the safe-traversal-operator `?.` to access properties as `ngIf` will only\n *    display the data if `userStream` returns a value.\n *  - We can display an alternative template while waiting for the data.\n *\n * ### Syntax\n *\n * Simple form:\n * - `<div *ngIf=\"condition\">...</div>`\n * - `<ng-template [ngIf]=\"condition\"><div>...</div></ng-template>`\n *\n * Form with an else block:\n * ```\n * <div *ngIf=\"condition; else elseBlock\">...</div>\n * <ng-template #elseBlock>...</ng-template>\n * ```\n *\n * Form with a `then` and `else` block:\n * ```\n * <div *ngIf=\"condition; then thenBlock else elseBlock\"></div>\n * <ng-template #thenBlock>...</ng-template>\n * <ng-template #elseBlock>...</ng-template>\n * ```\n *\n * Form with storing the value locally:\n * ```\n * <div *ngIf=\"condition as value; else elseBlock\">{{value}}</div>\n * <ng-template #elseBlock>...</ng-template>\n * ```\n *\n * @ngModule CommonModule\n */\nvar NgIf = /** @class */ (function () {\n    function NgIf(_viewContainer, templateRef) {\n        this._viewContainer = _viewContainer;\n        this._context = new NgIfContext();\n        this._thenTemplateRef = null;\n        this._elseTemplateRef = null;\n        this._thenViewRef = null;\n        this._elseViewRef = null;\n        this._thenTemplateRef = templateRef;\n    }\n    Object.defineProperty(NgIf.prototype, \"ngIf\", {\n        set: function (condition) {\n            this._context.$implicit = this._context.ngIf = condition;\n            this._updateView();\n        },\n        enumerable: true,\n        configurable: true\n    });\n    Object.defineProperty(NgIf.prototype, \"ngIfThen\", {\n        set: function (templateRef) {\n            assertTemplate('ngIfThen', templateRef);\n            this._thenTemplateRef = templateRef;\n            this._thenViewRef = null;

To localize dates\n * in another language, you must import the corresponding locale data.\n * See the [I18n guide](guide/i18n#i18n-pipes) for more information.\n *\n * @see `formatDate()`\n *\n *\n * @usageNotes\n *\n * The result of this pipe is not reevaluated when the input is mutated. To avoid the need to\n * reformat the date on every change-detection cycle, treat the date as an immutable object\n * and change the reference when the pipe needs to run again.\n *\n * ### Pre-defined format options\n *\n * Examples are given in `en-US` locale.\n *\n * - `'short'`: equivalent to `'M/d/yy, h:mm a'` (`6/15/15, 9:03 AM`).\n * - `'medium'`: equivalent to `'MMM d, y, h:mm:ss a'` (`Jun 15, 2015, 9:03:01 AM`).\n * - `'long'`: equivalent to `'MMMM d, y, h:mm:ss a z'` (`June 15, 2015 at 9:03:01 AM\n * GMT+1`).\n * - `'full'`: equivalent to `'EEEE, MMMM d, y, h:mm:ss a zzzz'` (`Monday, June 15, 2015 at\n * 9:03:01 AM GMT+01:00`).\n * - `'shortDate'`: equivalent to `'M/d/yy'` (`6/15/15`).\n * - `'mediumDate'`: equivalent to `'MMM d, y'` (`Jun 15, 2015`).\n * - `'longDate'`: equivalent to `'MMMM d, y'` (`June 15, 2015`).\n * - `'fullDate'`: equivalent to `'EEEE, MMMM d, y'` (`Monday, June 15, 2015`).\n * - `'shortTime'`: equivalent to `'h:mm a'` (`9:03 AM`).\n * - `'mediumTime'`: equivalent to `'h:mm:ss a'` (`9:03:01 AM`).\n * - `'longTime'`: equivalent to `'h:mm:ss a z'` (`9:03:01 AM GMT+1`).\n * - `'fullTime'`: equivalent to `'h:mm:ss a zzzz'` (`9:03:01 AM GMT+01:00`).\n *\n * ### Custom format options\n *\n * You can construct a format string using symbols to specify the components\n * of a date-time value, as described in the following table.\n * Format details depend on the locale.\n * Fields marked with (*) are only available in the extra data set for the given locale.\n *\n *  | Field type         | Format      | Description

* Note that timezone correction is not applied to an ISO string that has no time component, such as \"2016-09-19\"\n *\n * ### Format examples\n *\n * These examples transform a date into various formats,\n * assuming that `dateObj` is a JavaScript `Date` object for\n * year: 2015, month: 6, day: 15, hour: 21, minute: 43, second: 11,\n * given in the local time for the `en-US` locale.\n *\n * ```\n * {{ dateObj | date }}               // output is 'Jun 15, 2015'\n * {{ dateObj | date:'medium' }}      // output is 'Jun 15, 2015, 9:43:11 PM'\n * {{ dateObj | date:'shortTime' }}   // output is '9:43 PM'\n * {{ dateObj | date:'mmss' }}        // output is '43:11'\n * ```\n *\n * ### Usage example\n *\n * The following component uses a date pipe to display the current date in different formats.\n *\n * ```\n * @Component({\n *  selector: 'date-pipe',\n *  template: `<div>\n *    <p>Today is {{today | date}}</p>\n *    <p>Or if you prefer, {{today | date:'fullDate'}}</p>\n *    <p>The time is {{today | date:'h:mm a z'}}</p>\n *  </div>`\n * })\n * // Get the current date and time as a date-time value.\n * export class DatePipeComponent {\n *   today: number = Date.now();\n * }\n * ```\n *\n */\n// clang-format on\nvar DatePipe = /** @class */ (function () {\n    function DatePipe(locale) {\n        this.locale = locale;\n    }\n    DatePipe_1 = DatePipe;\n    /**\n     *

It encodes inheritance, properties, and events.\n *\n * ## Overview\n *\n * Each line represents one kind of element. The `element_inheritance` and properties are joined\n * using `element_inheritance|properties` syntax.\n *\n * ## Element Inheritance\n *\n * The `element_inheritance` can be further subdivided as `element1,element2,...^parentElement`.\n * Here the individual elements are separated by `,` (commas). Every element in the list\n * has identical properties.\n *\n * An `element` may inherit additional properties from `parentElement` If no `^parentElement` is\n * specified then `\"\"` (blank) element is assumed.\n *\n * NOTE: The blank element inherits from root `[Element]` element, the super element of all\n * elements.\n *\n * NOTE an element prefix such as `:svg:` has no special meaning to the schema.\n *\n * ## Properties\n *\n * Each element has a set of properties separated by `,` (commas). Each property can be prefixed\n * by a special character designating its type:\n *\n * - (no prefix): property is a string.\n * - `*`: property represents an event.\n * - `!`: property is a boolean.\n * - `#`: property is a number.\n * - `%`: property is an object.\n *\n * ## Query\n *\n * The class creates an internal squas representation which allows to easily answer the query of\n * if a given property exist on a given element.\n *\n * NOTE: We don't yet support querying for types or events.\n * NOTE: This schema is auto extracted from `schema_extractor.ts` located in the test folder,\n *       see dom_element_schema_registry_spec.ts\n */\n// =================================================================================================\n// =================================================================================================\n// =========== S T O P   -  S T O P   -  S T O P   -  S T O P   -  S T O P   -  S T O P  ===========\n// =================================================================================================\n// =================================================================================================\n//\n//                       DO NOT EDIT THIS DOM SCHEMA WITHOUT A SECURITY REVIEW!\n//\n// Newly added properties must be security reviewed and assigned an appropriate SecurityContext in\n// dom_security_schema.ts.

The goal is to allow users to avoid the\n  most obvious pitfalls and do so without compromising performance significantly.\n  For ShadowDOM styling that's not covered here, a set of best practices\n  can be provided that should allow users to accomplish more complex styling.\n\n  The following is a list of specific ShadowDOM styling features and a brief\n  discussion of the approach used to shim.\n\n  Shimmed features:\n\n  * :host, :host-context: ShadowDOM allows styling of the shadowRoot's host\n  element using the :host rule. To shim this feature, the :host styles are\n  reformatted and prefixed with a given scope name and promoted to a\n  document level stylesheet.\n  For example, given a scope name of .foo, a rule like this:\n\n    :host {\n        background: red;\n      }\n    }\n\n  becomes:\n\n    .foo {\n      background: red;\n    }\n\n  * encapsulation: Styles defined within ShadowDOM, apply only to\n  dom inside the ShadowDOM. Polymer uses one of two techniques to implement\n  this feature.\n\n  By default, rules are prefixed with the host element tag name\n  as a descendant selector. This ensures styling does not leak out of the 'top'\n  of the element's ShadowDOM. For example,\n\n  div {\n      font-weight: bold;\n    }\n\n  becomes:\n\n  x-foo div {\n      font-weight: bold;\n    }\n\n  becomes:\n\n\n  Alternatively, if WebComponents.ShadowCSS.strictStyling is set to true then\n  selectors are scoped by adding an attribute selector suffix to each\n  simple selector that contains the host element tag name. Each element\n  in the element's ShadowDOM template is also given the scope attribute.\n  Thus, these rules match only elements that have the scope attribute.\n  For example, given a scope name of x-foo, a rule like this:\n\n    div {\n      font-weight: bold;\n    }\n\n  becomes:\n\n    div[x-foo] {\n      font-weight: bold;\n    }\n\n  Note that elements that are dynamically added to a scope must have the scope\n  selector added to them manually.\n\n  * upper/lower bound encapsulation: Styles which are defined outside a\n  shadowRoot should not cross the ShadowDOM boundary and should not apply\n  inside a shadowRoot.\n\n  This styling behavior is not emulated. Some possible ways to do this that\n  were rejected due to complexity and/or performance concerns include: (1) reset\n  every possible property for every possible selector for a given scope name;\n  (2) re-implement css in javascript.\n\n  As an alternative, users should make sure to use selectors\n  specific to the scope in which they are working.\n\n  * ::distributed: This behavior is not emulated. It's often not necessary\n  to style the contents of a specific insertion point and instead, descendants\n  of the host element can be styled selectively. Users can also create an\n  extra node around an insertion point and style that node's contents\n  via descendent selectors. For example, with a shadowRoot like this:\n\n    <style>\n      ::content(div) {\n        background: red;\n      }\n    </style>\n    <content></content>\n\n  could become:\n\n    <style>\n      / *@polyfill .content-container div * /\n      ::content(div) {\n        background: red;\n      }\n    </style>\n    <div class=\"content-container\">\n      <content></content>\n    </div>\n\n  Note the use of @polyfill in the comment above a ShadowDOM specific style\n  declaration. This is a directive to the styling shim to use the selector\n  in comments in lieu of the next selector when running under polyfill.\n*/\nvar ShadowCss = /** @class */ (function () {\n    function ShadowCss() {\n        this.strictStyling = true;\n    }\n    /*\n    * Shim some cssText with the given selector.

The trigger is attached to an element in the component's\n * template, using \"@_trigger_name_\", and a state expression that is evaluated\n * at run time to determine whether the animation should start.\n *\n * ```typescript\n * @Component({\n *   selector: 'animation-cmp',\n *   templateUrl: 'animation-cmp.html',\n *   animations: [\n *     trigger('myTriggerName', [\n *       state('on', style({ opacity: 1 }),\n *       state('off', style({ opacity: 0 }),\n *       transition('on => off', [\n *         animate(\"1s\")\n *       ])\n *     ])\n *   ]\n * })\n * ```\n *\n * ```html\n * <!-- animation-cmp.html -->\n * <div @myTriggerName=\"expression\">...</div>\n * ```\n *\n * ### Preserving whitespace\n *\n * Removing whitespace can greatly reduce AOT-generated code size, and speed up view creation.\n * As of Angular 6, default for `preserveWhitespaces` is false (whitespace is removed).\n * To change the default setting for all components in your application, set\n * the `preserveWhitespaces` option of the AOT compiler.\n *\n * Current implementation removes whitespace characters as follows:\n * - Trims all whitespaces at the beginning and the end of a template.\n * - Removes whitespace-only text nodes. For example,\n * `<button>Action 1</button>  <button>Action 2</button>` becomes\n * `<button>Action 1</button><button>Action 2</button>`.\n * - Replaces a series of whitespace characters in text nodes with a single space.\n * For example, `<span>\\n some text\\n</span>` becomes `<span> some text </span>`.\n * - Does NOT alter text nodes inside HTML tags such as `<pre>` or `<textarea>`,\n * where whitespace characters are significant.\n *\n * Note that these transformations can influence DOM nodes layout, although impact\n * should be minimal.\n *\n * You can override the default behavior to preserve whitespace characters\n * in certain fragments of a template. For example, you can exclude an entire\n * DOM sub-tree by using the `ngPreserveWhitespaces` attribute:\n *\n * ```html\n * <div ngPreserveWhitespaces>\n *     whitespaces are preserved here\n *     <span>    and here </span>\n * </div>\n * ```\n *\n * You can force a single space to be preserved in a text node by using `&ngsp;`,\n * which is replaced with a space character by Angular's template\n * compiler:\n *\n * ```html\n * <a>Spaces</a>&ngsp;<a>between</a>&ngsp;<a>links.</a>\n * <!-->compiled to be equivalent to:</>\n *  <a>Spaces</a> <a>between</a> <a>links.</a>\n * ```\n *\n * Note that sequences of `&ngsp;` are still collapsed to just one space character when\n * the `preserveWhitespaces` option is set to `false`.\n *\n * ```html\n * <a>before</a>&ngsp;&ngsp;&ngsp;<a>after</a>\n * <!-->compiled to be equivalent to:</>\n *  <a>Spaces</a> <a>between</a> <a>links.</a>\n * ```\n *\n * To preserve sequences of whitespace characters, use the\n * `ngPreserveWhitespaces` attribute.\n *\n * @Annotation\n */\nvar Component = makeDecorator('Component', function (c) {\n    if (c === void 0) { c = {}; }\n    return (__assign({ changeDetection: ChangeDetectionStrategy.Default }, c));\n}, Directive, undefined, function (type, meta) { return (function () { })(type, meta); });\n/**\n *\n *\n * @Annotation\n */\nvar Pipe = makeDecorator('Pipe', function (p) { return (__assign({ pure: true }, p)); }, undefined, undefined, function (type, meta) { return (function () { })(type, meta); });\n/**\n *\n * @Annotation\n */\nvar Input = makePropDecorator('Input', function (bindingPropertyName) { return ({ bindingPropertyName: bindingPropertyName }); });\n/**\n *\n * @Annotation\n */\nvar Output = makePropDecorator('Output', function (bindingPropertyName) { return ({ bindingPropertyName: bindingPropertyName }); });\n/**\n *\n * @Annotation\n */\nvar HostBinding = makePropDecorator('HostBinding', function (hostPropertyName) { return ({ hostPropertyName: hostPropertyName }); });\n/**\n * Binds a CSS event to a host listener and supplies configuration metadata.\n * Angular invokes the supplied handler method when the host element emits the specified event,\n * and updates the bound element with the result.\n * If the handler method returns false, applies `preventDefault` on the bound element.\n *\n * @usageNotes\n *\n * The following example declares a directive\n * that attaches a click listener to a button and counts clicks.\n *\n * ```\n * @Directive({selector: 'button[counting]'})\n * class CountClicks {\n *   numberOfClicks = 0;\n *\n *   @HostListener('click', ['$event.target'])\n *   onClick(btn) {\n *     console.log('button', btn, 'number of clicks:', this.numberOfClicks++);\n *  }\n * }\n *\n * @Component({\n *   selector: 'app',\n *   template: '<button counting>Increment</button>',\n * })\n * class App {}\n * ```\n *\n * @Annotation\n */\nvar HostListener = makePropDecorator('HostListener', function (eventName, args) { return ({ eventName: eventName, args: args }); });\n\n/**\n * @license\n * Copyright Google Inc.

hooks (depending on the node\n// flags in lifecycle). Unlike ngDoCheck, ngOnChanges and ngOnInit, which are\n// called during a pre-order traversal of the view tree (that is calling the\n// parent hooks before the child hooks) these events are sent in using a\n// post-order traversal of the tree (children before parents). This changes the\n// meaning of initIndex in the view state. For ngOnInit, initIndex tracks the\n// expected nodeIndex which a ngOnInit should be called. When sending\n// ngAfterContentInit and ngAfterViewInit it is the expected count of\n// ngAfterContentInit or ngAfterViewInit methods that have been called. This\n// ensure that despite being called recursively or after picking up after an\n// exception, the ngAfterContentInit or ngAfterViewInit will be called on the\n// correct nodes. Consider for example, the following (where E is an element\n// and D is a directive)\n//  Tree:       pre-order index  post-order index\n//    E1        0                6\n//      E2      1                1\n//       D3     2                0\n//      E4      3                5\n//       E5     4                4\n//        E6    5                2\n//        E7    6                3\n// As can be seen, the post-order index has an unclear relationship to the\n// pre-order index (postOrderIndex === preOrderIndex - parentCount +\n// childCount). Since number of calls to ngAfterContentInit and ngAfterViewInit\n// are stable (will be the same for the same view regardless of exceptions or\n// recursion) we just need to count them which will roughly correspond to the\n// post-order index (it skips elements and directives that do not have\n// lifecycle hooks).\n//\n// For example, if an exception is raised in the E6.onAfterViewInit() the\n// initIndex is left at 3 (by shouldCallLifecycleInitHook() which set it to\n// initIndex + 1).

You do\n * **not** need to add a special selector to activate it.\n *\n * @usageNotes\n * ### How to use select controls with form directives\n *\n * To use a select in a template-driven form, simply add an `ngModel` and a `name`\n * attribute to the main `<select>` tag.\n *\n * If your option values are simple strings, you can bind to the normal `value` property\n * on the option.  If your option values happen to be objects (and you'd like to save the\n * selection in your form as an object), use `ngValue` instead:\n *\n * {@example forms/ts/selectControl/select_control_example.ts region='Component'}\n *\n * In reactive forms, you'll also want to add your form directive (`formControlName` or\n * `formControl`) on the main `<select>` tag. Like in the former example, you have the\n * choice of binding to the  `value` or `ngValue` property on the select's options.\n *\n * {@example forms/ts/reactiveSelectControl/reactive_select_control_example.ts region='Component'}\n *\n * ### Caveat: Option selection\n *\n * Angular uses object identity to select option.

For example, if one of the controls in a group is invalid, the entire\n * group becomes invalid.\n *\n * `FormGroup` is one of the three fundamental building blocks used to define forms in Angular,\n * along with `FormControl` and `FormArray`.\n *\n * When instantiating a `FormGroup`, pass in a collection of child controls as the first\n * argument.

For example, if one of\n * the controls in a `FormArray` is invalid, the entire array becomes invalid.\n *\n * `FormArray` is one of the three fundamental building blocks used to define forms in Angular,\n * along with `FormControl` and `FormGroup`.\n *\n * @usageNotes\n *\n * ### Create an array of form controls\n *\n * ```\n * const arr = new FormArray([\n *   new FormControl('Nancy', Validators.minLength(2)),\n *   new FormControl('Drew'),\n * ]);\n *\n * console.log(arr.value);   // ['Nancy', 'Drew']\n * console.log(arr.status);  // 'VALID'\n * ```\n *\n * ### Create a form array with array-level validators\n *\n * You include array-level validators and async validators. These come in handy\n * when you want to perform validation that considers the value of more than one child\n * control.\n *\n * The two types of validators are passed in separately as the second and third arg\n * respectively, or together as part of an options object.\n *\n * ```\n * const arr = new FormArray([\n *   new FormControl('Nancy'),\n *   new FormControl('Drew')\n * ], {validators: myValidator, asyncValidators: myAsyncValidator});\n * ```\n *\n  * ### Set the updateOn property for all controls in a form array\n *\n * The options object is used to set a default value for each child\n * control's `updateOn` property. If you set `updateOn` to `'blur'` at the\n * array level, all child controls default to 'blur', unless the child\n * has explicitly specified a different `updateOn` value.\n *\n * ```ts\n * const arr = new FormArray([\n *    new FormControl()\n * ], {updateOn: 'blur'});\n * ```\n *\n * ### Adding or removing controls from a form array\n *\n * To change the controls in the array, use the `push`, `insert`, or `removeAt` methods\n * in `FormArray` itself. These methods ensure the controls are properly tracked in the\n * form's hierarchy.

If you have a two-way binding with `[()]` syntax\n * (also known as 'banana-box syntax'), the value in the UI will always be synced back to\n * the domain model in your class as well.\n *\n * If you wish to inspect the properties of the associated `FormControl` (like\n * validity state), you can also export the directive into a local template variable using\n * `ngModel` as the key (ex: `#myVar=\"ngModel\"`).

Conversely,\n * any values written to the DOM element through user input will be reflected in the\n * `FormControl` instance (view -> model).\n *\n * @usageNotes\n * Use this directive if you'd like to create and manage a `FormControl` instance directly.\n * Simply create a `FormControl`, save it to your component class, and pass it into the\n * `FormControlDirective`.\n *\n * This directive is designed to be used as a standalone control.  Unlike `FormControlName`,\n * it does not require that your `FormControl` instance be part of any parent\n * `FormGroup`, and it won't be registered to any `FormGroupDirective` that\n * exists above it.\n *\n * **Get the value**: the `value` property is always synced and available on the\n * `FormControl` instance. See a full list of available properties in\n * `AbstractControl`.\n *\n * **Set the value**: You can pass in an initial value when instantiating the `FormControl`,\n * or you can set it programmatically later using {@link AbstractControl#setValue setValue} or\n * {@link AbstractControl#patchValue patchValue}.\n *\n * **Listen to value**: If you want to listen to changes in the value of the control, you can\n * subscribe to the {@link AbstractControl#valueChanges valueChanges} event.  You can also listen to\n * {@link AbstractControl#statusChanges statusChanges} to be notified when the validation status is\n * re-calculated.\n *\n * ### Example\n *\n * {@example forms/ts/simpleFormControl/simple_form_control_example.ts region='Component'}\n *\n * ### Use with ngModel\n *\n * Support for using the `ngModel` input property and `ngModelChange` event with reactive\n * form directives has been deprecated in Angular v6 and will be removed in Angular v7.\n *\n * Now deprecated:\n *\n * ```html\n * <input [formControl]=\"control\" [(ngModel)]=\"value\">\n * ```\n *\n * ```ts\n * this.value = 'some value';\n * ```\n *\n * This has been deprecated for a few reasons. First, developers have found this pattern\n * confusing. It seems like the actual `ngModel` directive is being used, but in fact it's\n * an input/output property named `ngModel` on the reactive form directive that simply\n * approximates (some of) its behavior. Specifically, it allows getting/setting the value\n * and intercepting value events. However, some of `ngModel`'s other features - like\n * delaying updates with`ngModelOptions` or exporting the directive - simply don't work,\n * which has understandably caused some confusion.\n *\n * In addition, this pattern mixes template-driven and reactive forms strategies, which\n * we generally don't recommend because it doesn't take advantage of the full benefits of\n * either strategy. Setting the value in the template violates the template-agnostic\n * principles behind reactive forms, whereas adding a `FormControl`/`FormGroup` layer in\n * the class removes the convenience of defining forms in the template.\n *\n * To update your code before v7, you'll want to decide whether to stick with reactive form\n * directives (and get/set values using reactive forms patterns) or switch over to\n * template-driven directives.\n *\n * After (choice 1 - use reactive forms):\n *\n * ```html\n * <input [formControl]=\"control\">\n * ```\n *\n * ```ts\n * this.control.setValue('some value');\n * ```\n *\n * After (choice 2 - use template-driven forms):\n *\n * ```html\n * <input [(ngModel)]=\"value\">\n * ```\n *\n * ```ts\n * this.value = 'some value';\n * ```\n *\n * By default, when you use this pattern, you will see a deprecation warning once in dev\n * mode. You can choose to silence this warning by providing a config for\n * `ReactiveFormsModule` at import time:\n *\n * ```ts\n * imports: [\n *   ReactiveFormsModule.withConfig({warnOnNgModelWithFormControl: 'never'});\n * ]\n * ```\n *\n * Alternatively, you can choose to surface a separate warning for each instance of this\n * pattern with a config value of `\"always\"`. This may help to track down where in the code\n * the pattern is being used as the code is being updated.\n *\n * @ngModule ReactiveFormsModule\n */\nvar FormControlDirective = /** @class */ (function (_super) {\n    __extends(FormControlDirective, _super);\n    function FormControlDirective(validators, asyncValidators, valueAccessors, _ngModelWarningConfig) {\n        var _this = _super.call(this) || this;\n        _this._ngModelWarningConfig = _ngModelWarningConfig;\n        /** @deprecated as of v6 */\n        _this.update = new EventEmitter();\n        /**\n         * Instance property used to track whether an ngModel warning has been sent out for this\n         * particular FormControlDirective instance.

Conversely,\n * any values written to the DOM element through user input will be reflected in the\n * `FormControl` instance (view -> model).\n *\n * @usageNotes\n * This directive is designed to be used with a parent `FormGroupDirective` (selector:\n * `[formGroup]`).\n *\n * It accepts the string name of the `FormControl` instance you want to\n * link, and will look for a `FormControl` registered with that name in the\n * closest `FormGroup` or `FormArray` above it.\n *\n * **Access the control**: You can access the `FormControl` associated with\n * this directive by using the {@link AbstractControl#get get} method.\n * Ex: `this.form.get('first');`\n *\n * **Get value**: the `value` property is always synced and available on the `FormControl`.\n * See a full list of available properties in `AbstractControl`.\n *\n *  **Set value**: You can set an initial value for the control when instantiating the\n *  `FormControl`, or you can set it programmatically later using\n *  {@link AbstractControl#setValue setValue} or {@link AbstractControl#patchValue patchValue}.\n *\n * **Listen to value**: If you want to listen to changes in the value of the control, you can\n * subscribe to the {@link AbstractControl#valueChanges valueChanges} event.  You can also listen to\n * {@link AbstractControl#statusChanges statusChanges} to be notified when the validation status is\n * re-calculated.\n *\n * ### Example\n *\n * In this example, we create form controls for first name and last name.\n *\n * {@example forms/ts/simpleFormGroup/simple_form_group_example.ts region='Component'}\n *\n * To see `formControlName` examples with different form control types, see:\n *\n * * Radio buttons: `RadioControlValueAccessor`\n * * Selects: `SelectControlValueAccessor`\n *\n * ### Use with ngModel\n *\n * Support for using the `ngModel` input property and `ngModelChange` event with reactive\n * form directives has been deprecated in Angular v6 and will be removed in Angular v7.\n *\n * Now deprecated:\n *\n * ```html\n * <form [formGroup]=\"form\">\n *   <input formControlName=\"first\" [(ngModel)]=\"value\">\n * </form>\n * ```\n *\n * ```ts\n * this.value = 'some value';\n * ```\n *\n * This has been deprecated for a few reasons. First, developers have found this pattern\n * confusing. It seems like the actual `ngModel` directive is being used, but in fact it's\n * an input/output property named `ngModel` on the reactive form directive that simply\n * approximates (some of) its behavior. Specifically, it allows getting/setting the value\n * and intercepting value events. However, some of `ngModel`'s other features - like\n * delaying updates with`ngModelOptions` or exporting the directive - simply don't work,\n * which has understandably caused some confusion.\n *\n * In addition, this pattern mixes template-driven and reactive forms strategies, which\n * we generally don't recommend because it doesn't take advantage of the full benefits of\n * either strategy. Setting the value in the template violates the template-agnostic\n * principles behind reactive forms, whereas adding a `FormControl`/`FormGroup` layer in\n * the class removes the convenience of defining forms in the template.\n *\n * To update your code before v7, you'll want to decide whether to stick with reactive form\n * directives (and get/set values using reactive forms patterns) or switch over to\n * template-driven directives.\n *\n * After (choice 1 - use reactive forms):\n *\n * ```html\n * <form [formGroup]=\"form\">\n *   <input formControlName=\"first\">\n * </form>\n * ```\n *\n * ```ts\n * this.form.get('first').setValue('some value');\n * ```\n *\n * After (choice 2 - use template-driven forms):\n *\n * ```html\n * <input [(ngModel)]=\"value\">\n * ```\n *\n * ```ts\n * this.value = 'some value';\n * ```\n *\n * By default, when you use this pattern, you will see a deprecation warning once in dev\n * mode. You can choose to silence this warning by providing a config for\n * `ReactiveFormsModule` at import time:\n *\n * ```ts\n * imports: [\n *   ReactiveFormsModule.withConfig({warnOnNgModelWithFormControl: 'never'});\n * ]\n * ```\n *\n * Alternatively, you can choose to surface a separate warning for each instance of this\n * pattern with a config value of `\"always\"`. This may help to track down where in the code\n * the pattern is being used as the code is being updated.\n *\n * @ngModule ReactiveFormsModule\n */\nvar FormControlName = /** @class */ (function (_super) {\n    __extends(FormControlName, _super);\n    function FormControlName(parent, validators, asyncValidators, valueAccessors, _ngModelWarningConfig) {\n        var _this = _super.call(this) || this;\n        _this._ngModelWarningConfig = _ngModelWarningConfig;\n        _this._added = false;\n        /** @deprecated as of v6 */\n        _this.update = new EventEmitter();\n        /**\n         * Instance property used to track whether an ngModel warning has been sent out for this\n         * particular FormControlName instance.
