Class ConstrainableAID

java.lang.Object

java.rmi.activation.ActivationID

org.apache.river.phoenix.dl.AID

org.apache.river.phoenix.dl.ConstrainableAID

All Implemented Interfaces:

Serializable, net.jini.core.constraint.RemoteMethodControl, net.jini.security.proxytrust.TrustEquivalence

public final class ConstrainableAID
extends AID
implements net.jini.core.constraint.RemoteMethodControl, net.jini.security.proxytrust.TrustEquivalence

A subclass of AID that implements the RemoteMethodControl interface by delegating to the contained activator.

This class exists as a convenience for activation system daemon implementations supporting RemoteMethodControl on proxies, to avoid requiring all such implementations to make code available for dynamic download to clients.

Since:

2.0

Constructor Detail

ConstrainableAID

public ConstrainableAID(Activator activator,
                        UID uid)

Creates an activation identifier containing the specified remote object activator, a new unique identifier, and null client constraints.

Parameters:

activator - the activator

uid - the unique identifier

Throws:

IllegalArgumentException - if the specified activator is not an instance of RemoteMethodControl or TrustEquivalence

Method Detail

setConstraints

public net.jini.core.constraint.RemoteMethodControl setConstraints(net.jini.core.constraint.MethodConstraints constraints)

Returns a new copy of this activation identifier containing the same unique identifier and a copy of the activator with the new specified constraints.

Specified by:

setConstraints in interface net.jini.core.constraint.RemoteMethodControl

Parameters:

constraints - the client constraints, or null

Returns:

a new copy of this activation identifier containing the same unique identifier and a copy of the activator with the new specified client constraints

getConstraints()

getConstraints

public net.jini.core.constraint.MethodConstraints getConstraints()

Returns the client constraints.

Specified by:

getConstraints in interface net.jini.core.constraint.RemoteMethodControl

Returns:

the client constraints, or null

setConstraints(net.jini.core.constraint.MethodConstraints)

checkTrustEquivalence

public boolean checkTrustEquivalence(Object obj)

Returns true if the object is an instance of this class with the same UID and a trust equivalent activator.

Specified by:

checkTrustEquivalence in interface net.jini.security.proxytrust.TrustEquivalence
