public class: ActivationID
All Implemented Interfaces:
Activation makes use of special identifiers to denote remote
objects that can be activated over time. An activation identifier
(an instance of the class
) contains several
pieces of information needed for activating an object:
- a remote reference to the object's activator (a RemoteRef
- a unique identifier (a 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
- via the first
Activatable constructor (that takes
three arguments and both registers and exports the object, and
- via the first
that takes the activation descriptor, object and port as arguments;
this method both registers and exports the object.
public ActivationID(Activator activator)
The constructor for
ActivationID takes a single
argument, activator, that specifies a remote reference to the
activator responsible for activating the object associated with
this identifier. An instance of
ActivationID is globally
activator - reference to the activator responsible for
activating the object
|Methods from java.lang.Object:|
clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait|
|Method from java.rmi.activation.ActivationID Detail:|
public Remote activate(boolean force) throws ActivationException, UnknownObjectException, RemoteException
Activate the object for this id.
public boolean equals(Object obj)
Compares two activation ids for content equality.
Returns true if both of the following conditions are true:
1) the unique identifiers equivalent (by content), and
2) the activator specified in each identifier
refers to the same remote object.
public int hashCode()
Returns a hashcode for the activation id. Two identifiers that
refer to the same remote object will have the same hash code.
