public class DefaultSingleSelectionModel extends Object implements SingleSelectionModel, Serializable
A generic implementation of SingleSelectionModel.
Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beans
package. Please see XMLEncoder

Returns an array of all the change listeners registered on this DefaultSingleSelectionModel
.

, removeChangeListener(javax.swing.event.ChangeListener)
protected void fireStateChanged()
Notifies all listeners that have registered interest for notification on this event type. The event instance is created lazily.
EventListenerList
public <T extends EventListener> T[] getListeners(Class<T> listenerType)
Returns an array of all the objects currently registered as FooListener
s upon this model. 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

- if listenerType
doesn't specify a class or interface that implements java.util.EventListener
