Abstract class to easily create forms that are template driven.
CheckboxControlValueAccessor
The accessor for writing a value and listening to changes on a checkbox input element.
Control<T>
Defines a part of a form that cannot be divided into other controls. Controls have values and validation state, which is determined by an optional validation function.
ControlArray
Defines a part of a form, of variable length, that can contain other controls.
ControlContainer<T extends AbstractControlGroup>
A directive that contains multiple NgControls contained in a AbstractControlGroup.
ControlGroup
Defines a part of a form, of fixed length, that can contain other controls.
ControlValueAccessor<T>
A bridge between a control and a native element.
DefaultValueAccessor
The default accessor for writing a value and listening to changes that is used by the NgModel, NgFormControl, and NgControlName directives.
Form
An interface that NgFormModel and NgForm implement.
FormBuilder
Creates a form object from a user-specified configuration.
MaxLengthValidator
A Directive adding minimum-length validator to controls with maxlength.
MemorizedForm
A form that will not remove controls if the control is taken out of the view for example with a NgIf.
MinLengthValidator
A Directive adding minimum-length validator to controls with minlength.
NgControl
A base class that all control directive extend. It binds a Control object to a DOM element.

NgControlStatus
Directive automatically applied to Angular forms that sets CSS classes based on control status (valid/invalid/dirty/etc).
NgForm
If NgForm is bound in a component, <form> elements in that component will be upgraded to use the Angular form system.
NgFormControl
Binds an existing Control to a DOM element.
NgFormModel
Binds an existing control group to a DOM element.
NgModel
