Class GJSAServer

java.lang.Object
  java.lang.Thread
      biz.chitec.quarterback.gjsa.server.GJSAServer

All Implemented Interfaces:: java.lang.Runnable

Direct Known Subclasses:: QJChatServer, SyncBurstReceiverDemo.SyncBurstDemoServer

public abstract class GJSAServer
extends java.lang.Thread

GJSA server main base. The master main thread of a GJSA server. This one listens on the port and instanciates new ServerThreadHandlers for every new connection. Furthermore, it handles the storage of overall server properties and controls the encryption engine for the GJSA connection, if available.
