Interfaces describing events and event listeners, and concrete event implementation classes.

See: Description

Interface Summary

Interface	Description
ActionListener	A listener interface for receiving ActionEvents.
AjaxBehaviorListener	By implementing this class, an object indicates that it is a listener for one or more kinds of BehaviorEvents.
BehaviorListener	A generic base interface for event listeners for various types of BehaviorEvents.
ComponentSystemEventListener	Implementors of this class do not need an isListenerForSource() method because they are only installed on specific component instances, therefore the isListenerForSource() method is implicit.
FacesListener	A generic base interface for event listeners for various types of FacesEvents.
PhaseListener	An interface implemented by objects that wish to be notified at the beginning and ending of processing for each standard phase of the request processing lifecycle.
SystemEventListener	By implementing this class, an object indicates that it is a listener for one or more kinds of SystemEvents.
SystemEventListenerHolder	Classes that implement this interface agree to maintain a list of SystemEventListener instances for each kind of SystemEvent they can generate.
ValueChangeListener	A listener interface for receiving ValueChangeEvents.
ViewMapListener	Marker interface for SystemEvents that indicate the view map has been created (PostConstructViewMapEvent, or destroyed (PreDestroyViewMapEvent).

Class Summary

Class	Description
ActionEvent	An ActionEvent represents the activation of a user interface component (such as a UICommand).
ActionListenerWrapper	Provides a simple implementation of ActionListener that can be subclassed by developers wishing to provide specialized behavior to an existing ActionListener instance.
AjaxBehaviorEvent	AjaxBehaviorEvent represents the component behavior specific to Ajax).
BehaviorEvent	BehaviorEvent is the event that can be generated from component Behavior.
ComponentSystemEvent	ComponentSystemEvent is the base class for SystemEvents that are specific to a UIComponent instance.
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.
ExceptionQueuedEventContext	This helper class provides context to the ExceptionQueuedEvent regarding the state of the system at the point in time when the ExceptionQueuedEvent occurs and links the ExceptionQueuedEvent to the ExceptionHandler by virtue of implementing SystemEventListener.
FacesEvent	FacesEvent is the base class for user interface and application events that can be fired by UIComponents.
MethodExpressionActionListener	MethodExpressionActionListener is an ActionListener that wraps a MethodExpression.
MethodExpressionValueChangeListener	MethodExpressionValueChangeListener is a ValueChangeListener that wraps a MethodExpression.
PhaseEvent	PhaseEvent represents the beginning or ending of processing for a particular phase of the request processing lifecycle, for the request encapsulated by the specified FacesContext.
PhaseId	Typesafe enumeration of the legal values that may be returned by the getPhaseId() method of the FacesEvent interface.
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.
PostConstructApplicationEvent	This event must be published by the runtime after all configuration resources have been parsed and processed.
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.
PostConstructViewMapEvent	This event must be published by a call to {javax.faces.application.Application#publishEvent} when the view map is first created.
PostKeepFlashValueEvent	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 a value is kept in the flash.
PostPutFlashValueEvent	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 a value is stored in the flash.
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.
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.
PreClearFlashEvent	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) before the flash is cleared.
PreDestroyApplicationEvent	This event must be published by the runtime before the factories associated with this Application are released.
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.
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().
PreRemoveFlashValueEvent	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 a value is removed from the flash.
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.
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.
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.
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.
ScopeContext	A structure that contains the name of the scope and the scope itself exposed as a Map<String, Object>.
SystemEvent	SystemEvent is the base class for non-application specific events that can be fired by arbitrary objects.
ValueChangeEvent	A ValueChangeEvent is a notification that the local value of the source component has been change as a result of user interface activity.

Exception Summary

Exception	Description
AbortProcessingException	An exception that may be thrown by event listeners to terminate the processing of the current event.

Annotation Types Summary

Annotation Type	Description
ListenerFor	Classes tagged with this annotation are installed as listeners using the method Application.subscribeToEvent(java.lang.Class<? extends javax.faces.event.SystemEvent>, java.lang.Class<?>, javax.faces.event.SystemEventListener) or UIComponent.subscribeToEvent(java.lang.Class<? extends javax.faces.event.SystemEvent>, javax.faces.event.ComponentSystemEventListener) (depending on the circumstances, described below).
ListenersFor	Container annotation to specify multiple ListenerFor annotations on a single class.
NamedEvent	The presence of this annotation on a class automatically registers the class with the runtime as a ComponentSystemEvent for use with the <f:event /> tag in a page.

Package javax.faces.event Description

Interfaces describing events and event listeners, and concrete event implementation classes. All events extend from FacesEvent and all listeners extend from FacesListener.
