- ActionEvent, BehaviorEvent, ValueChangeEvent
public abstract class FacesEvent extends EventObject
FacesEvent is the base class for user interface and application events that can be fired by
UIComponent
s. Concrete event classes must subclassFacesEvent
in order to be supported by the request processing lifecycle.- See Also:

Constructor Detail
-
FacesEvent
public FacesEvent(UIComponent component)
Construct a new event object from the specified source component.
- Parameters:
component
- SourceUIComponent
for this event- Throws:
IllegalArgumentException
- ifcomponent
isnull
-
-
Method Detail
-
getComponent
public UIComponent getComponent()
Return the source
UIComponent
that sent this event.
-
getPhaseId
public PhaseId getPhaseId()
Return the identifier of the request processing phase during which this event should be delivered. Legal values are the singleton instances defined by the
PhaseId
class, includingPhaseId.ANY_PHASE
, which is the default value.
-
setPhaseId
public void setPhaseId(PhaseId phaseId)
Set the
PhaseId
during which this event will be delivered.- Throws:
IllegalArgumentException
- phaseId is null.
-
queue
public void queue()
Convenience method to queue this event for broadcast at the end of the current request processing lifecycle phase.
- Throws:
IllegalStateException
- if the source component for this event is not a descendant of aUIViewRoot
-
isAppropriateListener
public abstract boolean isAppropriateListener(FacesListener listener)
Return
true
if thisFacesListener
is an instance of a listener class that this event supports. Typically, this will be accomplished by an "instanceof" check on the listener class.- Parameters:
listener
-FacesListener
to evaluate
-
processListener
public abstract void processListener(FacesListener listener)
Broadcast this
FacesEvent
to the specifiedFacesListener
, by whatever mechanism is appropriate. Typically, this will be accomplished by calling an event processing method, and passing thisFacesEvent
as a paramter.- Parameters:
listener
-FacesListener
to send thisFacesEvent
to- Throws:
AbortProcessingException
- Signal the JavaServer Faces implementation that no further processing on the current event should be performed
