Package Summary Overview Summary

### class:DefaultSingleSelectionModel [NONE]
- All Implemented Interfaces: Serializable, SingleSelectionModel
      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`. Since: 1.2

### field:changeEvent [NONE]
- #### changeEvent
      protected transient ChangeEvent changeEvent

### field:listenerList [NONE]
- #### listenerList
      protected EventListenerList listenerList
The collection of registered listeners

### constructor:DefaultSingleSelectionModel() [NONE]
- #### DefaultSingleSelectionModel
      public DefaultSingleSelectionModel()

### method:getSelectedIndex() [NONE]
- #### getSelectedIndex
      public int getSelectedIndex()
Description copied from interface: `SingleSelectionModel` Returns the model's selection. Specified by: `getSelectedIndex` in interface `SingleSelectionModel` Returns: the model's selection, or -1 if there is no selection See Also: `SingleSelectionModel.setSelectedIndex(int)`

### method:setSelectedIndex(int) [NONE]
- #### setSelectedIndex
      public void setSelectedIndex(int index)
Description copied from interface: `SingleSelectionModel` Sets the model's selected index to index. Notifies any listeners if the model changes Specified by: `setSelectedIndex` in interface `SingleSelectionModel` Parameters: `index` - an int specifying the model selection See Also: `SingleSelectionModel.getSelectedIndex()`, `SingleSelectionModel.addChangeListener(javax.swing.event.ChangeListener)`

### method:clearSelection() [NONE]
- #### clearSelection
      public void clearSelection()
Description copied from interface: `SingleSelectionModel` Clears the selection (to -1). Specified by: `clearSelection` in interface `SingleSelectionModel`

### method:isSelected() [NONE]
- #### isSelected
      public boolean isSelected()
Description copied from interface: `SingleSelectionModel` Returns true if the selection model currently has a selected value. Specified by: `isSelected` in interface `SingleSelectionModel` Returns: true if a value is currently selected

### method:addChangeListener(javax.swing.event.ChangeListener) [NONE]
- #### addChangeListener
      public void addChangeListener(ChangeListener l)
Adds a `ChangeListener` to the button. Specified by: `addChangeListener` in interface `SingleSelectionModel` Parameters: `l` - the ChangeListener to add

### method:removeChangeListener(javax.swing.event.ChangeListener) [NONE]
- #### removeChangeListener
      public void removeChangeListener(ChangeListener l)
Removes a `ChangeListener` from the button. Specified by: `removeChangeListener` in interface `SingleSelectionModel` Parameters: `l` - the ChangeListener to remove

### method:getChangeListeners() [NONE]
- #### getChangeListeners
      public ChangeListener[] getChangeListeners()
Returns an array of all the change listeners registered on this `DefaultSingleSelectionModel`. Returns: all of this model's `ChangeListener`s or an empty array if no change listeners are currently registered Since: 1.4 See Also: `addChangeListener(javax.swing.event.ChangeListener)`, `removeChangeListener(javax.swing.event.ChangeListener)`

### method:fireStateChanged() [NONE]
- #### fireStateChanged
      protected void fireStateChanged()
Notifies all listeners that have registered interest for notification on this event type. The event instance is created lazily. See Also: `EventListenerList`

### method:getListeners(java.lang.Class) [NONE]
- #### getListeners
      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. Type Parameters: `T` - the type of `EventListener` class being requested Parameters: `listenerType` - the type of listeners requested; this parameter should specify an interface that descends from `java.util.EventListener` Returns: an array of all objects registered as `FooListener`s on this model, or an empty array if no such listeners have been added Throws: `ClassCastException` - if `listenerType` doesn't specify a class or interface that implements `java.util.EventListener` Since: 1.3 See Also: `getChangeListeners()`
