afterEventDelivery

protected void afterEventDelivery()

Called just after the EventListener.onEvent(EventIterator) method has been called (even if the call threw an exception). The default implementation of this method does nothing, but subclasses can override it to add custom processing.

getTrackedListener

public EventListener getTrackedListener()

getListenerMBean

public org.apache.jackrabbit.api.jmx.EventListenerMBean getListenerMBean()

toString
