Class ActivatableRef

Implemented Interfaces:
Externalizable, ProtocolConstants, RemoteRef, Serializable
public class ActivatableRef
extends UnicastRef
The activatable reference works like UnicastRef, but if the remote object appears to be not accessible, it tries to reactivate it before reporting any errors. Apart the fields of the UnicastRef, the activatable reference contains the ActivationID that is used for this activation.
