java.lang.Object javax.faces.component.behavior.BehaviorBase
public class BehaviorBase
BehaviorBase is a
convenience base class that provides a default implementation of the
Behavior
contract. It also provides behavior listener registration
and state saving support.

public void broadcast(BehaviorEvent event) throws AbortProcessingException
Default implementation of
Behavior#broadcast
. Delivers the specified
BehaviorEvent
to all registered BehaviorListener
event listeners who have expressed an interest in events of
this type. Listeners are called in the order in which they were
registered (added).

implementation that no further processing on the current event

public void clearInitialState()
Clears the initial state flag, causing the behavior to revert from partial to full state saving.

protected void addBehaviorListener(BehaviorListener listener)
Add the specified BehaviorListener
to the set of listeners registered to receive event notifications
from this Behavior
.
It is expected that Behavior
classes acting as event sources
will have corresponding typesafe APIs for registering listeners of the
required type, and the implementation of those registration methods
will delegate to this method. For example:
public class AjaxBehaviorEvent extends BehaviorEvent { ... } public interface AjaxBehaviorListener extends BehaviorListener { public void processAjaxBehavior(FooEvent event); } public class AjaxBehavior extends ClientBehaviorBase { ... public void addAjaxBehaviorListener(AjaxBehaviorListener listener) { addBehaviorListener(listener); } public void removeAjaxBehaviorListener(AjaxBehaviorListener listener) { removeBehaviorListener(listener); } ... }
listener
- The BehaviorListener
to be registered
java.lang.NullPointerException
- if listener
is null
protected void removeBehaviorListener(BehaviorListener listener)
Remove the specified
BehaviorListener
from the set of listeners
registered to receive event notifications from this
Behavior
.
listener
- The BehaviorListener
to be deregistered
java.lang.NullPointerException
- if listener
is null
