public interface SystemEventListenerHolder
Classes that implement this interface
agree to maintain a list of SystemEventListener
instances
for each kind of SystemEvent
they can generate. This
interface enables arbitrary Objects to act as the source for SystemEvent
instances.
If the implementing class is a UIComponent
or is referenced by a
UIComponent
, care must be taken to ensure that the
implementing class, and all the members of the list returned by
getListenersForEventClass(java.lang.Class<? extends javax.faces.event.SystemEvent>)
work correctly with the state
management system. One way to ensure this is to have the class and
the list members implement StateHolder
or Serializable
.
Modifier and Type | Method and Description |
---|---|
List<SystemEventListener> |
getListenersForEventClass(Class<? extends SystemEvent> facesEventClass)
|
List<SystemEventListener> getListenersForEventClass(Class<? extends SystemEvent> facesEventClass)
Return a List
of SystemEventListener
instances that have been installed into the class implementing
this interface.
