jakarta.faces.event

public Interface SystemEventListenerHolder

Known Direct Implementers
jakarta.faces.component.UIComponent, jakarta.faces.event.ExceptionQueuedEventContext
Imports
java.util.List

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 jakarta.faces.component.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 work correctly with the state management system. One way to ensure this is to have the class and the list members implement jakarta.faces.component.StateHolder or java.io.Serializable.
