Member Function Documentation

template<class Listener, class Event>
virtual void VUtil::ListenerTask< Listener, Event >::doTask (  )  [inline, virtual]

The actual task.

Because this is a generic template, we don't know ahead of time what method on the listener we actually want to call. So we call the method deliverTo() on the event, and pass it the listener object; this has event deliver itself to the listener by calling the appropriate method on the listener.

Implements VUtil::Task.
