Example 2 with Behavior

use of jakarta.faces.component.behavior.Behavior in project myfaces by apache.

the class UIComponentBase method broadcast.

/**
 * Invoke any listeners attached to this object which are listening for an event whose type matches the specified
 * event's runtime type.
 * <p>
 * This method does not propagate the event up to parent components, ie listeners attached to parent components
 * don't automatically get called.
 * <p>
 * If any of the listeners throws AbortProcessingException then that exception will prevent any further listener
 * callbacks from occurring, and the exception propagates out of this method without alteration.
 * <p>
 * ActionEvent events are typically queued by the renderer associated with this component in its decode method;
 * ValueChangeEvent events by the component's validate method. In either case the event's source property references
 * a component. At some later time the UIViewRoot component iterates over its queued events and invokes the
 * broadcast method on each event's source object.
 *
 * @param event
 *            must not be null.

@Override
public void broadcast(FacesEvent event) throws AbortProcessingException {

        behavior.broadcast((BehaviorEvent) event);
    }

        return;

    // perf: _facesListeners is RandomAccess instance (jakarta.faces.component._DeltaList)
    for (int i = 0, size = _facesListeners.size(); i < size; i++) {
        FacesListener facesListener = _facesListeners.get(i);
        if (event.isAppropriateListener(facesListener)) {
            event.processListener(facesListener);
        }
