Name

ActivationMonitor

Synopsis

An ActivationMonitor monitors a single activation group. It must be notified by the group when objects within the group become active or inactive, or when the group as a whole becomes inactive. This lets the ActivationMonitor know when an object needs to be (re)activated, for example.

                  
public interface ActivationMonitor extends Remote {
// Public Instance Methods
   public abstract void activeObject(ActivationID id, 
        MarshalledObject obj) throws UnknownObjectException, RemoteException;  
   public abstract void inactiveGroup(ActivationGroupID id, 
        long incarnation) throws UnknownGroupException, RemoteException;  
   public abstract void inactiveObject(
        ActivationID id) throws UnknownObjectException, RemoteException;  
}
