public class WatchdogServer

extends SimpleServer

A Watchdog server to watch for unexpected client deaths. Clients register by opening a socket with the server. If the client's socket closes without the client saying goodbye, then the clientDied(long id) method is called. if the client said goodbye and *then* the socket closed, then the clientLeft(long id) method is called. Override these methods to provide your own behaviour in these events. Note that there's also a threadsafe vector accessed via addClient(long), removeClient(long), and isClient(long).
