vbsServer

Class VbsServerShutdown

java.lang.Object

vbsServer.VbsServerShutdown

All Implemented Interfaces:

java.lang.Runnable

public class VbsServerShutdown
extends java.lang.Object
implements java.lang.Runnable

The class VbsServerShutdown is responsible for shutting down the VBS server nicely. It does so by closing all threads with their own stop() methods.

The class VbsServerShutdown is meant to be run when the application is shut down and should therefore be added as a shutdown hook thread (Runtime.getRuntime().addShutdownHook()). Note: shutdown hooks cannot be tested in Eclipse!

It is intended to run in its own thread.
