     public SystemEvent(Object source) {

     public boolean isAppropriateListener(FacesListener listener) {
 
         return (listener instanceof SystemEventListener);
 
     }


    

Broadcast this event instance to the specified FacesListener, by whatever mechanism is appropriate. Typically, this will be accomplished by calling an event processing method, and passing this instance as a paramter.

Parameters:
listener FacesListener to send this FacesEvent to
Throws:
AbortProcessingException Signal the JavaServer Faces implementation that no further processing on the current event should be performed
