Class QuitManager

java.lang.Object
  app.gui.QuitManager

public class QuitManager
extends java.lang.Object

A quit manager allows an app to perform an orderly shut down in response to any of several possible triggers. At construction time the owning app specifies a runnable defining the manager's fixed "pre-quit" sequence. The manager's public interface provides several forms of event-handler each triggering the manager's shut-down sequence. The shut-down sequence is performed by a separate thread, which runs the registered pre-quit sequence before exiting. The manager ensures that at most one instance of the shut-down thread is ever created and run by this manager.
