 *
 * If you have imported the {\@link FormsModule} or the {\@link ReactiveFormsModule}, this
 * value accessor will be active on any select control that has a form directive. You do
 * **not** need to add a special selector to activate it.
 *
 * ### How to use select controls with form directives
 *
 * To use a select in a template-driven form, simply add an `ngModel` and a `name`
 * attribute to the main `<select>` tag.
 *
 * If your option values are simple strings, you can bind to the normal `value` property
 * on the option.  If your option values happen to be objects (and you'd like to save the
 * selection in your form as an object), use `ngValue` instead:
 *
 * {\@example forms/ts/selectControl/select_control_example.ts region='Component'}
 *
 * In reactive forms, you'll also want to add your form directive (`formControlName` or
 * `formControl`) on the main `<select>` tag. Like in the former example, you have the
 * choice of binding to the  `value` or `ngValue` property on the select's options.
 *
 * {\@example forms/ts/reactiveSelectControl/reactive_select_control_example.ts region='Component'}
 *
 * ### Caveat: 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.
 *
 * #### Syntax
 *
 * ```
 * <select [compareWith]="compareFn"  [(ngModel)]="selectedCountries">
 *     <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 Firefox and IE:
 * https://bugzilla.mozilla.org/show_bug.cgi?id=1024350
 * https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/4660045/

/**
 * The accessor for writing a value and listening to changes on a select element.
 *
 *  ### Caveat: Options selection
 *
 * Angular uses object identity to select options. 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 multiple>` supports `compareWith`
 * input. `compareWith` takes a **function** which has two arguments: `option1` and `option2`.
 * If `compareWith` is given, Angular selects options by the return value of the function.
 *
 * #### Syntax
 *
 * ```
 * <select multiple [compareWith]="compareFn"  [(ngModel)]="selectedCountries">
 *     <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;
 * }
 * ```

/**
 * \@whatItDoes Tracks the value and validation status of an individual form control.
 *
 * It is one of the three fundamental building blocks of Angular forms, along with
 * {\@link FormGroup} and {\@link FormArray}.
 *
 * \@howToUse
 *
 * When instantiating a {\@link FormControl}, you can pass in an initial value as the
 * first argument. Example:
 *
 * ```ts
 * const ctrl = new FormControl('some value');
 * console.log(ctrl.value);     // 'some value'
 * ```
 *
 * You can also initialize the control with a form state object on instantiation,
 * which includes both the value and whether or not the control is disabled.
 * You can't use the value key without the disabled key; both are required
 * to use this way of initialization.
 *
 * ```ts
 * const ctrl = new FormControl({value: 'n/a', disabled: true});
 * console.log(ctrl.value);     // 'n/a'
 * console.log(ctrl.status);   // 'DISABLED'
 * ```
 *
 * The second {\@link FormControl} argument can accept one of three things:
 * * a sync validator function
 * * an array of sync validator functions
 * * an options object containing validator and/or async validator functions
 *
 * Example of a single sync validator function:
 *
 * ```ts
 * const ctrl = new FormControl('', Validators.required);
 * console.log(ctrl.value);     // ''
 * console.log(ctrl.status);   // 'INVALID'
 * ```
 *
 * Example using options object:
 *
 * ```ts
 * const ctrl = new FormControl('', {
 *    validators: Validators.required,
 *    asyncValidators: myAsyncValidator
 * });
 * ```
 *
 * The options object can also be used to define when the control should update.
 * By default, the value and validity of a control updates whenever the value
 * changes. You can configure it to update on the blur event instead by setting
 * the `updateOn` option to `'blur'`.
 *
 * ```ts
 * const c = new FormControl('', { updateOn: 'blur' });
 * ```
 *
 * You can also set `updateOn` to `'submit'`, which will delay value and validity
 * updates until the parent form of the control fires a submit event.
 *
 * See its superclass, {\@link AbstractControl}, for more properties and methods.

/**
 * \@whatItDoes Tracks the value and validity state of a group of {\@link FormControl}
 * instances.
 *
 * A `FormGroup` aggregates the values of each child {\@link FormControl} into one object,
 * with each control name as the key.  It calculates its status by reducing the statuses
 * 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 three fundamental building blocks used to define forms in Angular,
 * along with {\@link FormControl} and {\@link FormArray}.
 *
 * \@howToUse
 *
 * When instantiating a {\@link FormGroup}, pass in a collection of child controls as the first
 * argument. The key for each child will be the name under which it is registered.
 *
 * ### Example
 *
 * ```
 * 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'
 * ```
 *
 * You can also 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.
 *
 * ### Example
 *
 * ```
 * 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 {\@link FormControl} instances, you can alternatively 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});
 * ```
 *
 * The options object can also be 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 will default to 'blur', unless the child
 * has explicitly specified a different `updateOn` value.
 *
 * ```ts
 * const c = new FormGroup({
 *    one: new FormControl()
 * }, {updateOn: 'blur'});
 * ```

/**
 * \@whatItDoes Tracks the value and validity state of an array of {\@link FormControl},
 * {\@link FormGroup} or {\@link FormArray} instances.
 *
 * A `FormArray` aggregates the values of each child {\@link FormControl} into an array.
 * It calculates its status by reducing the statuses of its children. For example, if one of
 * the controls in a `FormArray` is invalid, the entire array becomes invalid.
 *
 * `FormArray` is one of the three fundamental building blocks used to define forms in Angular,
 * along with {\@link FormControl} and {\@link FormGroup}.
 *
 * \@howToUse
 *
 * When instantiating a {\@link FormArray}, pass in an array of child controls as the first
 * argument.
 *
 * ### Example
 *
 * ```
 * const arr = new FormArray([
 *   new FormControl('Nancy', Validators.minLength(2)),
 *   new FormControl('Drew'),
 * ]);
 *
 * console.log(arr.value);   // ['Nancy', 'Drew']
 * console.log(arr.status);  // 'VALID'
 * ```
 *
 * You can also 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 can be 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});
 * ```
 *
 * The options object can also be 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 will default to 'blur', unless the child
 * has explicitly specified a different `updateOn` value.
 *

 * ### Adding or removing controls
 *
 * To change the controls in the array, use the `push`, `insert`, or `removeAt` 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 will result in strange and unexpected behavior such
 * as broken change detection.

/**
 * \@whatItDoes Creates a top-level {\@link FormGroup} instance and binds it to a form
 * to track aggregate form value and validation status.
 *
 * \@howToUse
 *
 * 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 can 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
 * {\@link FormGroup} instance are duplicated on the directive itself, so a reference to it
 * will give 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, you'll want to use {\@link NgModel} with a
 * `name` attribute.  You can also use {\@link NgModelGroup} if you'd like to create
 * sub-groups within the form.
 *
 * You can listen to the directive's `ngSubmit` event to be notified when the user has
 * triggered a form submission. The `ngSubmit` event will be emitted with the original form
 * submission event.
 *
 * In template driven forms, all `<form>` tags are automatically tagged as `NgForm`.
 * If you want to import the `FormsModule` but skip its usage in some forms,
 * for example, to use native HTML5 validation, you can add `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.
 *
 * {\@example forms/ts/simpleForm/simple_form_example.ts region='Component'}
 *

/**
 * \@whatItDoes Creates a {\@link FormControl} instance from a domain model and binds it
 * to a form control element.
 *
 * The {\@link FormControl} instance will track the value, user interaction, and
 * validation status of the control and keep the view synced with the model. If used
 * within a parent form, the directive will also register itself with the form as a child
 * control.
 *
 * \@howToUse
 *
 * This directive can be used by itself or as part of a larger form. All you need is the
 * `ngModel` selector to activate it.
 *
 * It accepts a domain model as an optional {\@link Input}. If you have a one-way binding
 * to `ngModel` with `[]` syntax, changing the value of the domain model in the component
 * class will set the value in the view. If you have a two-way binding with `[()]` syntax
 * (also known as 'banana-box syntax'), the value in the UI will always be synced back to
 * the domain model in your class as well.
 *
 * If you wish to inspect the properties of the associated {\@link FormControl} (like
 * validity state), you can also 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, but most properties you'll need (like `valid` and `dirty`)
 * will fall through to the control anyway, so you can access them directly. You can see a
 * full list of properties directly available in {\@link AbstractControlDirective}.
 *
 * The following is an example of 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.
 *
 * It's worth noting that in the context of a parent form, you often can skip one-way or
 * two-way binding because the parent form will sync the value for you. You can access
 * its properties by exporting it into a local template variable using `ngForm` (ex:
 * `#f="ngForm"`). Then you can pass it where it needs to go on submit.
 *
 * 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.
 *
 * Take a look at an example of using `ngModel` within a form:
 *
 * {\@example forms/ts/simpleForm/simple_form_example.ts region='Component'}
 *
 * To see `ngModel` examples with different form control types, see:
 *
 * * Radio buttons: {\@link RadioControlValueAccessor}
 * * Selects: {\@link SelectControlValueAccessor}

/**
 * \@whatItDoes Syncs a standalone {\@link FormControl} instance to a form control element.
 *
 * In other words, this directive ensures that any values written to the {\@link FormControl}
 * instance programmatically will be written to the DOM element (model -> view). Conversely,
 * any values written to the DOM element through user input will be reflected in the
 * {\@link FormControl} instance (view -> model).
 *
 * \@howToUse
 *
 * Use this directive if you'd like to create and manage a {\@link FormControl} instance directly.
 * Simply create a {\@link FormControl}, save it to your component class, and pass it into the
 * {\@link FormControlDirective}.
 *
 * This directive is designed to be used as a standalone control.  Unlike {\@link FormControlName},
 * it does not require that your {\@link FormControl} instance be part of any parent
 * {\@link FormGroup}, and it won't be registered to any {\@link FormGroupDirective} that
 * exists above it.
 *
 * **Get the value**: the `value` property is always synced and available on the
 * {\@link FormControl} instance. See a full list of available properties in
 * {\@link AbstractControl}.
 *
 * **Set the value**: You can pass in an initial value when instantiating the {\@link FormControl},
 * or you can set it programmatically later using {\@link AbstractControl#setValue setValue} or
 * {\@link AbstractControl#patchValue patchValue}.
 *
 * **Listen to value**: If you want to listen to changes in the value of the control, you can
 * subscribe to the {\@link AbstractControl#valueChanges valueChanges} event.  You can also listen to
 * {\@link AbstractControl#statusChanges statusChanges} to be notified when the validation status is
 * re-calculated.
 *
 * ### Example
 *
 * {\@example forms/ts/simpleFormControl/simple_form_control_example.ts region='Component'}

 * \@whatItDoes Syncs a nested {\@link FormGroup} to a DOM element.
 *
 * \@howToUse
 *
 * This directive can only be used with a parent {\@link FormGroupDirective} (selector:
 * `[formGroup]`).
 *
 * It accepts the string name of the nested {\@link FormGroup} you want to link, and
 * will look for a {\@link FormGroup} registered with that name in the parent
 * {\@link FormGroup} instance you passed into {\@link FormGroupDirective}.
 *
 * Nested form groups can come in handy when you want to validate a sub-group of a
 * form separately from the rest or when you'd like to group the values of certain
 * controls into their own nested object.
 *
 * **Access the group**: You can access the associated {\@link FormGroup} using the
 * {\@link AbstractControl#get get} method. Ex: `this.form.get('name')`.
 *
 * You can also access individual controls within the group using dot syntax.
 * Ex: `this.form.get('name.first')`
 *
 * **Get the value**: the `value` property is always synced and available on the
 * {\@link FormGroup}. See a full list of available properties in {\@link AbstractControl}.
 *
 * **Set the value**: You can set an initial value for each child control when instantiating
 * the {\@link FormGroup}, or you can set it programmatically later using
 * {\@link AbstractControl#setValue setValue} or {\@link AbstractControl#patchValue patchValue}.
 *
 * **Listen to value**: If you want to listen to changes in the value of the group, you can
 * subscribe to the {\@link AbstractControl#valueChanges valueChanges} event.  You can also listen to
 * {\@link AbstractControl#statusChanges statusChanges} to be notified when the validation status is
 * re-calculated.
