java.lang.Objectjava.rmi.activation.ActivationID
public class ActivationID
Activation makes use of special identifiers to denote remote
objects that can be activated over time. An activation identifier
(an instance of the class ActivationID) contains several
pieces of information needed for activating an object:
RemoteRef
instance), and
UID
instance) for the object. An activation identifier for an object can be obtained by registering an object with the activation system. Registration is accomplished in a few ways:
Activatable.register method
Activatable constructor (that takes
three arguments and both registers and exports the object, and
Activatable.exportObject method
that takes the activation descriptor, object and port as arguments;
this method both registers and exports the object.
