Examples of java.rmi.activation.ActivationID

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:
- a remote reference to the object's activator (a {@link java.rmi.server.RemoteRef RemoteRef}instance), and
- a unique identifier (a {@link java.rmi.server.UID 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:
- via the Activatable.register method
- via the first Activatable constructor (that takes three arguments and both registers and exports the object, and
- via the first Activatable.exportObject method that takes the activation descriptor, object and port as arguments; this method both registers and exports the object.
