Enclosing interface:

Container

public static interface Container.PropertySetChangeNotifier
extends Serializable

The interface for adding and removing PropertySetChangeEvent listeners. By implementing this interface a class explicitly announces that it will generate a PropertySetChangeEvent when the set of property IDs supported by the container is modified.

A property set change means the addition, removal or other structural changes to the properties of a container. Changes concerning the set of items in the container and their property values are not property set changes.

Note that the general Java convention is not to explicitly declare that a class generates events, but to directly define the addListener and removeListener methods. That way the caller of these methods has no real way of finding out if the class really will send the events, or if it just defines the methods to be able to implement an interface.

addListener

void addListener(Container.PropertySetChangeListener listener)

Registers a new Property set change listener for this Container.

Parameters:

listener - The new Listener to be registered

removeListener

void removeListener(Container.PropertySetChangeListener listener)

Removes a previously registered Property set change listener.

Parameters:
