Creates a FormControl instance from a domain model and binds it to a form control element.

Creates and binds a FormGroup instance to a DOM element.

Marks <option> as dynamic, so Angular can be notified when options change.

The ControlValueAccessor for writing a number value and listening to number input changes. The value accessor is used by the FormControlDirective, FormControlName, and NgModel directives.

A directive that adds regex pattern validation to controls marked with the pattern attribute. The regex must match the entire control value. The directive is provided with the NG_VALIDATORS multi-provider list.

The ControlValueAccessor for writing radio control values and listening to radio control changes. The value accessor is used by the FormControlDirective, FormControlName, and NgModel directives.

The ControlValueAccessor for writing a range value and listening to range input changes. The value accessor is used by the FormControlDirective, FormControlName, and NgModel directives.

A directive that adds the required validator to any controls marked with the required attribute. The directive is provided with the NG_VALIDATORS multi-provider list.

The ControlValueAccessor for writing select control values and listening to select control changes. The value accessor is used by the FormControlDirective, FormControlName, and NgModel directives.
