Examples of javax.faces.event.ComponentSystemEventListener

javax.faces.event.ComponentSystemEventListener

Implementors of this class do not need an isListenerForSource() method because they are only installed on specific component instances, therefore the isListenerForSource() method is implicit. Also, the {@link #processEvent} method on this interface takes a {@link ComponentSystemEvent} because the event will always be associated witha {@link javax.faces.component.UIComponent} instance.
