Class RunGameInOwnJVM

java.lang.Object

java.lang.Thread

net.sf.colossus.webserver.RunGameInOwnJVM

All Implemented Interfaces:

java.lang.Runnable, IGameRunner

public class RunGameInOwnJVM
extends java.lang.Thread
implements IGameRunner

This class runs (starts and supervises) a Game on the Game Server (as opposed to: on the User's PC). It finds and reserves a port for it, starts it in a separate process and when the process terminates, join()s it and releases the port. If the game is run on a user's PC, the class RunGameInSameJVM will be used.
