Interface Item.PropertySetChangeNotifier

All Known Implementing Classes:

PropertysetItem

Enclosing interface:

Item

public static interface Item.PropertySetChangeNotifier

The interface for adding and removing PropertySetChangeEvent listeners. By implementing this interface a class explicitly announces that it will generate a PropertySetChangeEvent when its Property set is modified. 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.

Method Summary

void	addListener(Item.PropertySetChangeListener listener) Registers a new property set change listener for this Item.
void	removeListener(Item.PropertySetChangeListener listener) Removes a previously registered property set change listener.
