Interface Container.ItemSetChangeNotifier

All Known Implementing Classes:

ContainerHierarchicalWrapper, ContainerOrderedWrapper, HierarchicalContainer, IndexedContainer, Select, Table, Tree

Enclosing interface:

Container

public static interface Container.ItemSetChangeNotifier

The interface for adding and removing ItemSetChangeEvent listeners. By implementing this interface a class explicitly announces that it will generate a ItemSetChangeEvent when its contents are modified.

Note: 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(Container.ItemSetChangeListener listener) Adds an Item set change listener for the object.
void	removeListener(Container.ItemSetChangeListener listener) Removes the Item set change listener from the object.
