javax.faces.event (Java(TM) EE 7 Specification APIs)

Interface Summary
Interface	Description
ActionListener	A listener interface for receiving `ActionEvent`s.
AjaxBehaviorListener	By implementing this class, an object indicates that it is a listener for one or more kinds of `BehaviorEvent`s.
BehaviorListener	A generic base interface for event listeners for various types of `BehaviorEvent`s.
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 `FacesEvent`s.
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 `SystemEvent`s.
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 `ValueChangeEvent`s.
ViewMapListener	Marker interface for `SystemEvent`s 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 `SystemEvent`s 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 `UIComponent`s.
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.

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
