public abstract class AbstractMultipleCompositeComponent extends AbstractCompositeComponent
An abstract implementation of a composite component that can contain multiple components. Every child component must be added or removed using addComponent(Component) and removeComponent(Component), although other actions may take place. The component's validity is updated whenever a child comonent is added or removed from the component.
