If used\n * within a parent form, the directive will also register itself with the form as a child\n * control.\n * \n * \\@howToUse \n * \n * This directive can be used by itself or as part of a larger form. All you need is the\n * `ngModel` selector to activate it.\n * \n * It accepts a domain model as an optional {\\@link Input}. If you have a one-way binding\n * to `ngModel` with `[]` syntax, changing the value of the domain model in the component\n * class will set the value in the view. 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 {\\@link 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\"`). You can then access the control using the\n * directive's `control` property, but most properties you'll need (like `valid` and `dirty`)\n * will fall through to the control anyway, so you can access them directly. You can see a\n * full list of properties directly available in {\\@link AbstractControlDirective}.\n * \n * The following is an example of a simple standalone control using `ngModel`:\n * \n * {\\@example forms/ts/simpleNgModel/simple_ng_model_example.ts region='Component'}\n * \n * When using the `ngModel` within `<form>` tags, you'll also need to supply a `name` attribute\n * so that the control can be registered with the parent form under that name.\n * \n * It's worth noting that in the context of a parent form, you often can skip one-way or\n * two-way binding because the parent form will sync the value for you. You can access\n * its properties by exporting it into a local template variable using `ngForm` (ex:\n * `#f=\"ngForm\"`).

You don't need to add a special selector.\n * \n * You can export the directive into a local template variable using `ngForm` as the key\n * (ex: `#myForm=\"ngForm\"`). This is optional, but useful.  Many properties from the underlying\n * {\\@link FormGroup} instance are duplicated on the directive itself, so a reference to it\n * will give you access to the aggregate value and validity status of the form, as well as\n * user interaction properties like `dirty` and `touched`.\n * \n * To register child controls with the form, you'll want to use {\\@link NgModel} with a\n * `name` attribute.  You can also use {\\@link NgModelGroup} if you'd like to create\n * sub-groups within the form.\n * \n * You can listen to the directive's `ngSubmit` event to be notified when the user has\n * triggered a form submission.

You do\n * **not** need to add a special selector to activate it.\n * \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. It's possible for the identities of items\n * to change while the data does not. This can happen, for example, if the items are produced\n * from an RPC to the server, and that RPC is re-run. Even if the data hasn't changed, the\n * second response will produce objects with different identities.\n * \n * To customize the default option comparison algorithm, `<select>` supports `compareWith` input.\n * `compareWith` takes a **function** which has two arguments: `option1` and `option2`.\n * If `compareWith` is given, Angular selects option by the return value of the function.\n * \n * #### Syntax\n * \n * ```\n * <select [compareWith]=\"compareFn\"  [(ngModel)]=\"selectedCountries\">\n *     <option *ngFor=\"let country of countries\" [ngValue]=\"country\">\n *         {{country.name}}\n *     </option>\n * </select>\n * \n * compareFn(c1: Country, c2: Country): boolean {\n *     return c1 && c2 ? c1.id === c2.id : c1 === c2;\n * }\n * ```\n * \n * Note: We listen to the 'change' event because 'input' events aren't fired\n * for selects in Firefox and IE:\n * https://bugzilla.mozilla.org/show_bug.cgi?id=1024350\n * https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/4660045/\n * \n * * **npm package**: `\\@angular/forms`\n * \n * \\@stable\n */\nexport class SelectControlValueAccessor implements ControlValueAccessor {\n  value: any;\n/**\n * \\@internal\n */\n_optionMap: Map<string, any> = new Map<string, any>();\n/**\n * \\@internal\n */\n_idCounter: number = 0;\n\n  onChange = (_: any) => {};\n  onTouched = () => {};\n/**\n * @param {?} fn\n * @return {?}\n */\nset compareWith(fn: (o1: any, o2: any) => boolean) {\n    if (typeof fn !== 'function') {\n      throw new Error(`compareWith must be a function, but received ${JSON.stringify(fn)}`);\n    }\n    this._compareWith = fn;\n  }\nprivate _compareWith: (o1: any, o2: any) => boolean = looseIdentical;\n/**\n * @param {?} _renderer\n * @param {?} _elementRef\n */\nconstructor(private _renderer: Renderer2,\nprivate _elementRef: ElementRef) {}\n/**\n * @param {?} value\n * @return {?}\n */\nwriteValue(value: any): void {\n    this.value = value;\n    const /** @type {?} */ id: string|null = this._getOptionId(value);\n    if (id == null) {\n      this._renderer.setProperty(this._elementRef.nativeElement, 'selectedIndex', -1);\n    }\n    const /** @type {?} */ valueString = _buildValueString(id, value);\n    this._renderer.setProperty(this._elementRef.nativeElement, 'value', valueString);\n  }\n/**\n * @param {?} fn\n * @return {?}\n */\nregisterOnChange(fn: (value: any) => any): void {\n    this.onChange = (valueString: string) => {\n      this.value = this._getOptionValue(valueString);\n      fn(this.value);\n    };\n  }\n/**\n * @param {?} fn\n * @return {?}\n */\nregisterOnTouched(fn: () => any): void { this.onTouched = fn; }\n/**\n * @param {?} isDisabled\n * @return {?}\n */\nsetDisabledState(isDisabled: boolean): void {\n    this._renderer.setProperty(this._elementRef.nativeElement, 'disabled', isDisabled);\n  }\n/**\n * \\@internal\n * @return {?}\n */\n_registerOption(): string { return (this._idCounter++).toString(); }\n/**\n * \\@internal\n * @param {?} value\n * @return {?}\n */\n_getOptionId(value: any): string|null {\n    for (const /** @type {?} */ id of Array.from(this._optionMap.keys())) {\n      if (this._compareWith(this._optionMap.get(id), value)) return id;\n    }\n    return null;\n  }\n/**\n * \\@internal\n * @param {?} valueString\n * @return {?}\n */\n_getOptionValue(valueString: string): any {\n    const /** @type {?} */ id: string = _extractId(valueString);\n    return this._optionMap.has(id) ?
