public ListDataListener getListDataListeners () [Inherited From AbstractListModel]

Returns an array of all the list data listeners registered on this AbstractListModel.

Returns an array of all the list data listeners
registered on this AbstractListModel.
Returns: all of this model's ListDataListeners, or an empty array if no list data listeners are currently registered
Since: 1.4

public T getListeners (Class< T> listenerType) [Inherited From AbstractListModel]

Returns an array of all the objects currently registered as FooListeners upon this model.

Returns an array of all the objects currently registered as FooListeners upon this model. FooListeners 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 list model m for its list data listeners with the following code:

ListDataListener[] ldls = (ListDataListener[])(m.getListeners(ListDataListener.class));

If no such listeners exist, this method returns an empty array.
Returns: an array of all objects registered as FooListeners on this model, or an empty array if no such listeners have been added
Parameters:
- listenerType - the type of listeners requested; this parameter should specify an interface that descends from java.util.EventListener
Throws:
- ClassCastException - if listenerType doesn't specify a class or interface that implements java.util.EventListener
Since: 1.3
