## Properties

### `Optional` controlId

controlId?: string

- Defined in packages/angular/forms/src/lib/types.ts:72

### `Readonly` errors

errors: ValidationErrors

An object containing any errors generated by failing validation, or null if there are no errors.

Inherited from NgAbstractControl.errors

- Defined in node_modules/@angular/forms/index.d.ts:147

### `Readonly` events

events: Observable<ControlEvent<any>>

A multicasting observable that emits an event every time the state of the control changes. It emits for value, status, pristine or touched changes.

Note: On value change, the emit happens right after a value of this control is updated. The value of a parent control (for example if this FormControl is a part of a FormGroup) is updated later, so accessing a value of a parent control (using the `value` property) from the callback of this event might result in getting a value that has not been updated yet. Subscribe to the `events` of the parent control instead. For other event types, the events are emitted after the parent control has been updated.

Inherited from NgAbstractControl.events

- Defined in node_modules/@angular/forms/index.d.ts:190

### `Optional` fullControlPath

fullControlPath?: string

- Defined in packages/angular/forms/src/lib/types.ts:73

### `Readonly` pristine

pristine: boolean

A control is `pristine` if the user has not yet changed the value in the UI.

#### Returns

True if the user has not yet changed the value in the UI; compare `dirty`. Programmatic changes to a control's value do not mark it dirty.

Inherited from NgAbstractControl.pristine

- Defined in node_modules/@angular/forms/index.d.ts:155

### `Optional` readonly

readonly?: boolean

- Defined in packages/angular/forms/src/lib/types.ts:75

### `Optional` rxapFormDefinition

rxapFormDefinition?: FormDefinition<any, any, any>

- Defined in packages/angular/forms/src/lib/types.ts:74

### `Optional` stateChanges

stateChanges?: Subject<any>

- Defined in packages/angular/forms/src/lib/types.ts:76

### `Readonly` status

status: FormControlStatus

The validation status of the control.

#### See

FormControlStatus

These status values are mutually exclusive, so a control cannot be both valid AND invalid or invalid AND disabled.

Inherited from NgAbstractControl.status

- Defined in node_modules/@angular/forms/index.d.ts:93

### `Readonly` statusChanges

statusChanges: Observable<FormControlStatus>

A multicasting observable that emits an event every time the validation `status` of the control recalculates.

#### See

- FormControlStatus
- AbstractControl.status

TODO: this should be piped from events() but is breaking in G3

Inherited from NgAbstractControl.statusChanges

- Defined in node_modules/@angular/forms/index.d.ts:214

### `Readonly` touched

touched: boolean

True if the control is marked as `touched`.

A control is marked `touched` once the user has triggered a `blur` event on it.

Inherited from NgAbstractControl.touched

- Defined in node_modules/@angular/forms/index.d.ts:170

### value

value: T

Overrides NgAbstractControl.value

- Defined in packages/angular/forms/src/lib/types.ts:71

### `Readonly` valueChanges

valueChanges: Observable<any>

A multicasting observable that emits an event every time the value of the control changes, in the UI or programmatically. It also emits an event each time you call enable() or disable() without passing along {emitEvent: false} as a function argument.

Note: the emit happens right after a value of this control is updated. The value of a parent control (for example if this FormControl is a part of a FormGroup) is updated later, so accessing a value of a parent control (using the `value` property) from the callback of this event might result in getting a value that has not been updated yet. Subscribe to the `valueChanges` event of the parent control instead.

TODO: this should be piped from events() but is breaking in G3

Inherited from NgAbstractControl.valueChanges

- Defined in node_modules/@angular/forms/index.d.ts:204

## Accessors

  When you add or remove a validator at run time, you must call `updateValueAndValidity()` for the new validation to take effect.

  Adding a validator that already exists will have no effect. If duplicate validator functions are present in the `validators` array, only the first instance would be added to a form control.

  #### Parameters

  - validators: ValidatorFn | ValidatorFn[]

    The new validator function or functions to add to this control.

  #### Returns void

  Inherited from NgAbstractControl.addValidators

  - Defined in node_modules/@angular/forms/index.d.ts:256

  If the control has children, all children are also disabled.

  #### Parameters

  - `Optional` opts: {
    emitEvent?: boolean;
    onlySelf?: boolean;
    }

    Configuration options that determine how the control propagates changes and emits events after the control is disabled.

    - `emitEvent`: When true or not supplied (the default), the `statusChanges`, `valueChanges` and `events` observables emit events with the latest status and value when the control is disabled. When false, no events are emitted.

    - ##### `Optional` emitEvent?: boolean

    - ##### `Optional` onlySelf?: boolean

  #### Returns void

  #### See

  AbstractControl.status

  Inherited from NgAbstractControl.disable

  - Defined in node_modules/@angular/forms/index.d.ts:496

### enable

- get<P>(path): AbstractControl<ɵGetProperty<any, P>, ɵGetProperty<any, P>>

- Retrieves a child control given the control's name or path.

  This signature for `get` supports non-const (mutable) arrays. Inferred type information will not be as robust, so prefer to pass a `readonly` array if possible.

  #### Type Parameters

  - P extends string | (string | number)[]

  #### Parameters

  - path: P

  #### Returns AbstractControl<ɵGetProperty<any, P>, ɵGetProperty<any, P>>

  #### Returns any

  error data for that particular error. If the control or error is not present, null is returned.

  #### Description

  Reports error data for the control with the given path.

  #### Usage Notes

  For example, for the following `FormGroup`:

      form = new FormGroup({
        address: new FormGroup({ street: new FormControl() })
      });

  The path to the 'street' control from the root form would be 'address' -> 'street'.

  It can be provided to this method in one of two formats:

  1. An array of string control names, e.g. `['address', 'street']`
  2. A period-delimited list of control names in one string, e.g. `'address.street'`

    A list of control names that designates how to move from the current control to the control that should be queried for errors.

  #### Returns boolean

  whether the given error is present in the control at the given path.

  If the control is not present, false is returned.

  #### Description

  Reports whether the control with the given path has the error specified.

  #### Usage Notes

  For example, for the following `FormGroup`:

      form = new FormGroup({
        address: new FormGroup({ street: new FormControl() })
      });

  The path to the 'street' control from the root form would be 'address' -> 'street'.

  It can be provided to this method in one of two formats:

  1. An array of string control names, e.g. `['address', 'street']`
  2. A period-delimited list of control names in one string, e.g. `'address.street'`

  If no path is given, this method checks for the error on the current control.

  #### Parameters

  - `Optional` value: any
  - `Optional` options: Object

  #### Returns void

  Inherited from NgAbstractControl.reset

  - Defined in node_modules/@angular/forms/index.d.ts:540

### setAsyncValidators

- setAsyncValidators(validators): void

- Sets the asynchronous validators that are active on this control. Calling this overwrites any existing asynchronous validators.

  When you add or remove a validator at run time, you must call `updateValueAndValidity()` for the new validation to take effect.

  If you want to add a new validator without affecting existing ones, consider using `addAsyncValidators()` method instead.

  #### Parameters

  - validators: AsyncValidatorFn | AsyncValidatorFn[]

  #### Returns void

  Inherited from NgAbstractControl.setAsyncValidators

  - Defined in node_modules/@angular/forms/index.d.ts:243

### setErrors

- setErrors(errors, opts?): void

- Sets errors on a form control when running validations manually, rather than automatically.

  Calling `setErrors` also updates the validity of the parent control.

  #### Parameters

  - errors: ValidationErrors
  - `Optional` opts: {
    emitEvent?: boolean;
    }

    Configuration options that determine how the control propagates changes and emits events after the control errors are set.

    - `emitEvent`: When true or not supplied (the default), the `statusChanges` observable emits an event after the errors are set.

    - ##### `Optional` emitEvent?: boolean

  #### Returns void

  #### Usage Notes

  ### Manually set the errors for a control

      const login = new FormControl('someLogin');
      login.setErrors({
        notUnique: true
      });

      expect(login.valid).toEqual(false);
      expect(login.errors).toEqual({ notUnique: true });

      login.setValue('someOtherLogin');

      expect(login.valid).toEqual(true);

### setParent

- setParent(parent): void

- Sets the parent of the control

  #### Parameters

  - parent: FormGroup<any> | FormArray<any>

    The new parent.

  #### Returns void

  Inherited from NgAbstractControl.setParent

  - Defined in node_modules/@angular/forms/index.d.ts:528

### setValidators

- setValidators(validators): void

- Sets the synchronous validators that are active on this control. Calling this overwrites any existing synchronous validators.

  When you add or remove a validator at run time, you must call `updateValueAndValidity()` for the new validation to take effect.

  If you want to add a new validator without affecting existing ones, consider using `addValidators()` method instead.

  #### Parameters

  - validators: ValidatorFn | ValidatorFn[]

  #### Returns void

  Inherited from NgAbstractControl.setValidators

  - Defined in node_modules/@angular/forms/index.d.ts:232

### `Abstract` setValue

- setValue(value, options?): void

- Sets the value of the control. Abstract method (implemented in sub-classes).

  #### Parameters

  - value: any
  - `Optional` options: Object

  #### Returns void

  Inherited from NgAbstractControl.setValue

  - Defined in node_modules/@angular/forms/index.d.ts:532

### updateValueAndValidity

- updateValueAndValidity(opts?): void

- Recalculates the value and validation status of the control.

  By default, it also updates the value and validity of its ancestors.

  #### Parameters

  - `Optional` opts: {
    emitEvent?: boolean;
    onlySelf?: boolean;
    }

    Configuration options determine how the control propagates changes and emits events after updates and validity checks are applied.

    - `onlySelf`: When true, only update this control. When false or not supplied, update all direct ancestors. Default is false.
    - `emitEvent`: When true or not supplied (the default), the `statusChanges`, `valueChanges` and `events` observables emit events with the latest status and value when the control is updated. When false, no events are emitted.

    - ##### `Optional` emitEvent?: boolean

    - ##### `Optional` onlySelf?: boolean

  #### Returns void
