### errors

> `readonly` **errors**: `null` \| `E`

Defined in: [packages/angular/forms/src/lib/form-control.ts:59](https://gitlab.com/rxap/packages/-/blob/3eebed1be2bbb37bc0d65959f8fecbb850c0b8aa/packages/angular/forms/src/lib/form-control.ts#L59)

### errors$

> `readonly` **errors$**: `Observable`\<`null` \| `E`\>

Defined in: [packages/angular/forms/src/lib/form-control.ts:93](https://gitlab.com/rxap/packages/-/blob/3eebed1be2bbb37bc0d65959f8fecbb850c0b8aa/packages/angular/forms/src/lib/form-control.ts#L93)

### events

> `readonly` **events**: `Observable`\<`ControlEvent`\<`any`\>\>

Defined in: node\_modules/@angular/forms/index.d.ts:196

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

`UntypedFormControl.events`

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

#### See

 - FormControlStatus
 - [AbstractControl.status](../wiki/Interface.AbstractControl#status)

#### Overrides

`UntypedFormControl.statusChanges`

### touch$

### value$

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.

#### Overrides

`UntypedFormControl.valueChanges`

### addAsyncValidators()

> **addAsyncValidators**(`validators`): `void`

Defined in: node\_modules/@angular/forms/index.d.ts:270

Add an asynchronous validator or validators to this control, without affecting other
validators.

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.

#### Parameters

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

`AsyncValidatorFn` | `AsyncValidatorFn`[]

#### Returns

`void`

#### Inherited from

`UntypedFormControl.addAsyncValidators`

***

### addValidators()

> **addValidators**(`validators`): `void`

Defined in: node\_modules/@angular/forms/index.d.ts:258

Add a synchronous validator or validators to this control, without affecting other validators.

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

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

`ValidatorFn` | `ValidatorFn`[]

#### Returns

`void`

#### Inherited from

`UntypedFormControl.addValidators`

#### Inherited from

`UntypedFormControl.clearValidators`

***

### disable()

> **disable**(`opts`?): `void`

Defined in: node\_modules/@angular/forms/index.d.ts:498

Disables the control. This means the control is exempt from validation checks and
excluded from the aggregate value of any parent. Its status is `DISABLED`.

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

#### Parameters

##### opts?

Configuration options that determine how the control propagates
changes and emits events after the control is disabled.
* `onlySelf`: When true, mark only this control. When false or not supplied,
marks 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 disabled.
When false, no events are emitted.

###### emitEvent?

its validators.

By default, if the control has children, all children are enabled.

#### Parameters

Configure options that control how the control propagates changes and
emits events when marked as untouched
* `onlySelf`: When true, mark only this control. When false or not supplied,
marks all direct ancestors. Default is false.

#### Call Signature

> **get**\<`P`\>(`path`): `null` \| `AbstractControl`\<`ɵGetProperty`\<`any`, `P`\>, `ɵGetProperty`\<`any`, `P`\>\>

Defined in: node\_modules/@angular/forms/index.d.ts:613

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

`null` \| `AbstractControl`\<`ɵGetProperty`\<`any`, `P`\>, `ɵGetProperty`\<`any`, `P`\>\>

### getError()

> **getError**\<`K`\>(`errorCode`): `null` \| `E`\[`K`\]

#### Type Parameters

• **K** *extends* `string`

#### Parameters

##### errorCode

`K`

The code of the error to check

#### Returns

`null` \| `E`\[`K`\]

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`:

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

#### Overrides

`UntypedFormControl.getError`

***

### hasAsyncValidator()

Check whether an asynchronous validator function is present on this control. The provided
validator must be a reference to the exact same function that was provided.

#### Parameters

##### validator

`AsyncValidatorFn`

The asynchronous validator to check for presence. Compared by function
    reference.

#### Returns

`boolean`

Whether the provided asynchronous validator was found on this control.

#### Inherited from

#### Type Parameters

• **K** *extends* `string`

#### Parameters

##### errorCode

`K`

The code of the error to check

#### 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`:

```ts
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']`
1. 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.

Resets the form control, marking it `pristine` and `untouched`, and resetting
the value. The new value will be the provided value (if passed), `null`, or the initial value
if `nonNullable` was set in the constructor via FormControlOptions.

```ts
// By default, the control will reset to null.
const dog = new FormControl('spot');
dog.reset(); // dog.value is null

// If this flag is set, the control will instead reset to the initial value.
const cat = new FormControl('tabby', {nonNullable: true});

// A value passed to reset always takes precedence.
const fish = new FormControl('finn', {nonNullable: true});
fish.reset('bubble'); // fish.value is "bubble"
