java.lang.Object | +--java.rmi.activation.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:
An activation id 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.
