Class ListenersMap<Key>
java.lang.Object
cz.cuni.amis.utils.listener.ListenersMap<Key>
public class ListenersMap<Key>
- extends java.lang.Object
Map of the listeners according to some key.
Comes in handy when you need the map of Listeners<? extends Listener> and work
with them (otherwise you're doomed to write tedious and ugly for-cycles forever).
And believe me, you don't want to parametrize the class more further the 'Key'...
... just remember it must be used with instances of 'Listener' and Java-generics are hell.

of weak references). But it will usually return correct value.
