FooListener

FooListener
s
are registered using the addFooListener
method.
You can specify the listenerType
argument
with a class literal, such as FooListener.class
.
For example, you can query a DefaultSingleSelectionModel
instance m
for its change listeners
with the following code:
ChangeListener[] cls = (ChangeListener[])(m.getListeners(ChangeListener.class));If no such listeners exist, this method returns an empty array.
listenerType
- the type of listeners requested;
this parameter should specify an interface
that descends from java.util.EventListener
FooListener
s
on this model,
or an empty array if no such
listeners have been added
ClassCastException
- if listenerType
doesn't
specify a class or interface that implements
java.util.EventListener
