public interface ComponentSystemEventListener
extends FacesListener

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 processEvent(jakarta.faces.event.ComponentSystemEvent) method on this interface takes a ComponentSystemEvent because the event will always be associated with a UIComponent instance.

2.0
