The org.zkoss.zk.ui.util.DesktopCleanup interface

Listener:

org.zkoss.zk.ui.util.DesktopCleanup

A listener could implement DesktopCleanup to cleanup a desktop when it is being destroyed.

When ZK Loader is going to destroy a desktop, it invokes the cleanup method of this interface so that developers could plug the application-specific codes to cleanup a desktop.

Instantiation: An independent instance of the given class is instantiated each time before the method is invoked. It means it is thread safe, and all information stored in non-static members will be lost after called.
