Class EBGumManagerImpl

java.lang.Object
  org.ourgrid.peer.manager.gummanager.EBGumManagerImpl

Direct Known Subclasses:

FakeEBGumManagerImpl

public class EBGumManagerImpl
extends java.lang.Object

A EBGumManagerImpl controls GuMs that can be used by the peer. Dealing with local GuMs, it is notified about states change at a GridMachine that it knows and also notifies the EBPeerManager. When dealing with received GuMs from another peer, it will create a Proxy and hold information about its state. This is done by methods that create and remove proxies. When the Grid Machine is lost, EBGumManagerImpl MUST receive an invalidate call so it will remove the proxy.
