This method is called by sendNotification for each listener in order to send the notification to that listener.

This method is called by sendNotification for each listener in order to send the notification to that listener. It can be overridden in subclasses to change the behavior of notification delivery, for instance to deliver the notification in a separate thread.

The default implementation of this method is equivalent to

 listener.handleNotification(notif, handback);

Parameters:
- listener - the listener to which the notification is being delivered.
- notif - the notification being delivered to the listener.
- handback - the handback object that was supplied when the listener was added.
