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 java.beans.XMLEncoder.

Modifier and TypeField and Description
protected transient ChangeEvent
changeEvent

Only one ModelChangeEvent is needed per model instance since the event's only (read-only) state is the source property.

Constructor Summary

AccessConstructor and Description
public
DefaultSingleSelectionModel()

Constructs a DefaultSingleSelectionModel.

Method Summary

Modifier and TypeMethod and Description

fireStateChangedback to summary
protected void fireStateChanged()

Notifies all listeners that have registered interest for notification on this event type. The event instance is created lazily.

getChangeListenersback to summary
public ChangeListener[] getChangeListeners()

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

Returns:ChangeListener[]

all of this model's ChangeListeners or an empty array if no change listeners are currently registered

addChangeListener, removeChangeListener
getListenersback to summary
public <T extends EventListener> T[] getListeners(Class<T> listenerType)

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 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.
Parameters
<T>
the type of EventListener class being requested
listenerType:Class<T>

the type of listeners requested; this parameter should specify an interface that descends from java.util.EventListener

Returns:T[]

an array of all objects registered as FooListeners on this model, or an empty array if no such listeners have been added

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