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 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 StateHolder
or
Serializable
.
