Class ExceptionQueuedEventContext

java.lang.Object

javax.faces.event.ExceptionQueuedEventContext

All Implemented Interfaces:

SystemEventListenerHolder

public class ExceptionQueuedEventContext
extends Object
implements SystemEventListenerHolder

This helper class provides context to the ExceptionQueuedEvent regarding the state of the system at the point in time when the ExceptionQueuedEvent occurs and links the ExceptionQueuedEvent to the ExceptionHandler by virtue of implementing SystemEventListener.

Since:

2.0
