Uses of SystemEvent in javax.faces.application

Method parameters in javax.faces.application with type arguments of type SystemEvent

Modifier and Type	Method and Description
void	Application.publishEvent(FacesContext context, Class<? extends SystemEvent> systemEventClass, Class<?> sourceBaseType, Object source) This method functions exactly like Application.publishEvent(FacesContext,Class,Object), except the run-time must use the argument sourceBaseType to find the matching listener instead of using the Class of the source argument.
void	ApplicationWrapper.publishEvent(FacesContext context, Class<? extends SystemEvent> systemEventClass, Class<?> sourceBaseType, Object source) The default behavior of this method is to call Application.publishEvent(javax.faces.context.FacesContext, Class, Class, Object) on the wrapped Application object.
void	Application.publishEvent(FacesContext context, Class<? extends SystemEvent> systemEventClass, Object source) If FacesContext.isProcessingEvents() is true and there are one or more listeners for events of the type represented by systemEventClass, call those listeners, passing source as the source of the event.
void	ApplicationWrapper.publishEvent(FacesContext context, Class<? extends SystemEvent> systemEventClass, Object source) The default behavior of this method is to call Application.publishEvent(javax.faces.context.FacesContext, Class, Object) on the wrapped Application object.

Uses of SystemEvent in javax.faces.event

Subclasses of SystemEvent in javax.faces.event

Modifier and Type	Class and Description
class	ComponentSystemEvent ComponentSystemEvent is the base class for SystemEvents that are specific to a UIComponent instance.
class	ExceptionQueuedEvent The system event facility will create an instance of this class whenever Application.publishEvent(javax.faces.context.FacesContext, java.lang.Class<? extends javax.faces.event.SystemEvent>, java.lang.Object) is called with ExceptionQueuedEvent.class as systemEventClass argument.
class	PostAddToViewEvent When an instance of this event is passed to SystemEventListener.processEvent(javax.faces.event.SystemEvent) or ComponentSystemEventListener.processEvent(javax.faces.event.ComponentSystemEvent), the listener implementation may assume that the source of this event instance is a UIComponent instance and that either that instance or an ancestor of that instance was just added to the view.
class	PostConstructApplicationEvent This event must be published by the runtime after all configuration resources have been parsed and processed.
class	PostConstructCustomScopeEvent This class is provided to allow custom scopes to publish a "post construct" event in the same way that other scopes do to let the application become aware of the beginning of the scope.
class	PostConstructViewMapEvent This event must be published by a call to {javax.faces.application.Application#publishEvent} when the view map is first created.
class	PostRestoreStateEvent When an instance of this event is passed to SystemEventListener.processEvent(javax.faces.event.SystemEvent) or ComponentSystemEventListener.processEvent(javax.faces.event.ComponentSystemEvent), the listener implementation may assume that the source of this event instance is in a tree that has just had its state restored.
class	PostValidateEvent When an instance of this event is passed to SystemEventListener.processEvent(javax.faces.event.SystemEvent) or ComponentSystemEventListener.processEvent(javax.faces.event.ComponentSystemEvent), the listener implementation may assume that the source of this event instance is the UIComponent instance that is that has just been validated.
class	PreDestroyApplicationEvent This event must be published by the runtime before the factories associated with this Application are released.
class	PreDestroyCustomScopeEvent This class is provided to allow custom scopes to publish a "pre construct" event in the same way that other scopes do to let the application become aware of the beginning of the scope.
class	PreDestroyViewMapEvent This event must be published by a call to Application.publishEvent(javax.faces.context.FacesContext, java.lang.Class<? extends javax.faces.event.SystemEvent>, java.lang.Object) when the clear method is called on the map returned from UIViewRoot.getViewMap().
class	PreRemoveFromViewEvent When an instance of this event is passed to SystemEventListener.processEvent(javax.faces.event.SystemEvent) or ComponentSystemEventListener.processEvent(javax.faces.event.ComponentSystemEvent), the listener implementation may assume that the source of this event instance is a UIComponent instance that is about to be removed from the view.
class	PreRenderComponentEvent When an instance of this event is passed to SystemEventListener.processEvent(javax.faces.event.SystemEvent) or ComponentSystemEventListener.processEvent(javax.faces.event.ComponentSystemEvent), the listener implementation may assume that the source of this event instance is the UIComponent instance that is about to be rendered and that it is safe to call UIComponent.getParent(), UIComponent.getClientId(), and other methods that depend upon the component instance being in the view.
class	PreRenderViewEvent When an instance of this event is passed to SystemEventListener.processEvent(javax.faces.event.SystemEvent) or ComponentSystemEventListener.processEvent(javax.faces.event.ComponentSystemEvent), the listener implementation may assume that the source of this event instance is the UIViewRoot instance that is about to be rendered.
class	PreValidateEvent When an instance of this event is passed to SystemEventListener.processEvent(javax.faces.event.SystemEvent) or ComponentSystemEventListener.processEvent(javax.faces.event.ComponentSystemEvent), the listener implementation may assume that the source of this event instance is the UIComponent instance that is about to be validated.
