Class PreRemoveFromViewEvent
java.lang.Object
java.util.EventObject
javax.faces.event.SystemEvent
javax.faces.event.ComponentSystemEvent
javax.faces.event.PreRemoveFromViewEvent
- All Implemented Interfaces:
- java.io.Serializable
public class PreRemoveFromViewEvent
- extends ComponentSystemEvent
When an instance of this event is passed
to SystemEventListener#processEvent
or ComponentSystemEventListener#processEvent
, the listener
implementation may assume that the source
of this event
instance is a UIComponent
instance that is about to be
removed from the view. Therefore, the implementation may assume it
is safe to call UIComponent#getParent
, UIComponent#getClientId
, and other methods that depend upon the
component instance being added into the view.
