All Implemented Interfaces:

ActionListener, Serializable, Cloneable, EventListener, Action

public final class DummyAction
extends AbstractAction

Dummy Action implementation, an Action implementation which does nothing and only serves as an Action Property container. This is useful e.g. for JMenu, instances of which you can create using Action instances but where implementing the basic abstract method ActionListener#actionPerformed(ActionEvent) does not make any sense. This class is also an appropriate superclass for Action implementations that aren't interested in ActionEvents but other events.

Method Detail

actionPerformed

public void actionPerformed(ActionEvent e)

Invoked when an action occurs. The implementation of this method in DummyAction simply does nothing.

clone

protected Object clone()
                throws CloneNotSupportedException

Clones the abstract action. This gives the clone its own copy of the key/value list, which is not handled for you by Object.clone().

Overrides:

clone in class AbstractAction

Returns:

a clone of this instance.

Throws:

CloneNotSupportedException - if the object's class does not support the Cloneable interface. Subclasses that override the clone method can also throw this exception to indicate that an instance cannot be cloned.
