Class TrainUpdater

java.lang.Object
  jfreerails.server.TrainUpdater

All Implemented Interfaces:

java.io.Serializable, ServerAutomaton

public class TrainUpdater
extends java.lang.Object
implements ServerAutomaton

This class is used by the server to generate moves that add trains, move trains, and handle stops at stations. Note, the client should not use this class to build trains, instead it should request that a train gets built by setting production at an engine shop.
