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 JavaBeansTM
has been added to the java.beans
package.

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.

- the type of listeners requested;
this parameter should specify an interface
