public interface SystemEventListenerHolder
Classes that implement this interface agree to maintain a list of
SystemEventListener instances for each kind
SystemEvent they can generate. This interface enables arbitrary Objects to act as the source for
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
getListenersForEventClass(java.lang.Class<? extends jakarta.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
List<SystemEventListener> getListenersForEventClass(Class<? extends SystemEvent> facesEventClass)
SystemEventListener instances that have been installed into the class
