Class Server

java.lang.Object
  boardgame.Server

All Implemented Interfaces:

java.lang.Runnable

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

Generic boardgame server. TODO The winner determination in case of a client error won't make sense unless it's a 2-player game. TODO The facility for the board to issue moves by returning Move.BOARD as the turn has not been tested all that well. TODO handling of Move.getReceivers() is not well tested. To start a server, execute its run() method. This will listen for clients and launch handler threads for each before returning. Any further work is done by these handler threads. The GUI dispatch thread may also call certain methods. Note that the call to run() returns as soon as the ClientHandler threads are started. A note on synchronization: The methods of this class will be called by 3 types of threads: - A) The thread executing the run() method - B) The ClientHandler threads (started by the run() method) - C) The GUI Thread The entry points for these threads are synchronized on the Server object's lock, except for the run() method. This is because the thread would not release the lock while waiting for connections. For this reason it is unsafe to manipulate the Server object while the run() method may be executing, with the exception of the killServer() method. This could probably be fixed by using yet another thread to accept the connections. Calls to the GUI, if present, are done using the EventQueue.invokeLater() facility, so that they are invoked by the AWT event dispatch thread.
