Class ServerManager

java.lang.Object
  org.radrails.server.core.ServerManager

All Implemented Interfaces:

java.util.EventListener, org.eclipse.core.resources.IResourceChangeListener, java.io.Serializable

public class ServerManager

extends java.lang.Object

implements java.io.Serializable, org.eclipse.core.resources.IResourceChangeListener

Manages a collection of all servers. Operations on servers should be called through this class, because it notifies any listening views of changes to the server. The ServerManager manages all of the servers in the workspace. It is also the model represented by ServersView. When a new Server has been created, it should be added to ServerManager using addServer method. Similarly, to remove a Server, use the removeServer method. The ServerManager also maintains a list of Observer objects. These are conceptually the observers of the ServerManager, but actually the observers of the Servers maintained by the ServerManager. As such, the addServerObserver and deleteServerObserver methods should be used instead of the addObserver and deleteObserver methods on Server.
