jdk.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 RemoteRef instance), and 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 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.

->activation-idclj
(->activation-id activator)Constructor.
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 unique.
activator - reference to the activator responsible for activating the object - java.rmi.activation.Activator
throws: java.lang.UnsupportedOperationException - if and only if activation is not supported by this implementation
Constructor. 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 unique. activator - reference to the activator responsible for activating the object - `java.rmi.activation.Activator` throws: java.lang.UnsupportedOperationException - if and only if activation is not supported by this implementation
activateclj
(activate this force)Activate the object for this id.
force - if true, forces the activator to contact the group when activating the object (instead of returning a cached reference); if false, returning a cached value is acceptable. - boolean
returns: the reference to the active remote object - java.rmi.Remote
throws: java.rmi.activation.ActivationException - if activation fails
Activate the object for this id. force - if true, forces the activator to contact the group when activating the object (instead of returning a cached reference); if false, returning a cached value is acceptable. - `boolean` returns: the reference to the active remote object - `java.rmi.Remote` throws: java.rmi.activation.ActivationException - if activation fails
equalsclj
(equals this obj)Compares two activation ids for content equality. Returns true if both of the following conditions are true:
- the unique identifiers equivalent (by content), and
- the activator specified in each identifier refers to the same remote object.
obj - the Object to compare with - java.lang.Object
returns: true if these Objects are equal; false otherwise. - boolean
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.
obj - the Object to compare with - `java.lang.Object`
returns: true if these Objects are equal; false otherwise. - `boolean`hash-codeclj
(hash-code this)Returns a hashcode for the activation id. Two identifiers that refer to the same remote object will have the same hash code.
returns: a hash code value for this object. - int
Returns a hashcode for the activation id. Two identifiers that refer to the same remote object will have the same hash code. returns: a hash code value for this object. - `int`
