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:

Constructor Detail

ActivationID

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 unique.
Parameters:
activator - reference to the activator responsible for activating the object
Method Detail

activate

public Remote activate(boolean force) throws ActivationException, UnknownObjectException, RemoteException
Activate the object for this id.
Parameters:
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.
Returns:
the reference to the active remote object
Throws:
ActivationException - if activation fails
UnknownObjectException - if the object is unknown
RemoteException - if remote call fails

hashCode

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.
Overrides:
hashCode in class Object
See Also:
Hashtable

equals

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.
Parameters:
obj - the Object to compare with
Returns:
true if these Objects are equal; false otherwise.
Overrides:
equals in class Object
See Also:
Hashtable
