Interface SystemEventListener

ViewMapListener
All Known Implementing Classes:
ExceptionHandler, ExceptionHandlerWrapper

public interface SystemEventListener
extends FacesListener

By implementing this class, an object indicates that it is a listener for one or more kinds of SystemEvents. The exact type of event that will cause the implementing class's processEvent(javax.faces.event.SystemEvent) method to be called is indicated by the facesEventClass argument passed when the listener is installed using Application.subscribeToEvent(java.lang.Class<? extends javax.faces.event.SystemEvent>, java.lang.Class<?>, javax.faces.event.SystemEventListener).

Since:
2.0

 void processEvent(SystemEvent event)
