Constructor and Description
ProxyVerifier(OutriggerServer server, Uuid uuid) Returns a verifier for the smart proxies of an Outrigger server with the specified server reference.

Method Summary

Modifier and Type	Method and Description
boolean	isTrustedObject(Object obj, TrustVerifier.Context ctx) Returns true if the specified proxy object (that is not yet known to be trusted) is equivalent in trust, content, and function to the canonical server reference this object was constructed with; otherwise returns false.
private void	readObject(ObjectInputStream in) Verifies that the server reference implements TrustEquivalence.

Constant Field Values

server

private final RemoteMethodControl server

The canonical instance of the server reference. This instance will be used by the isTrusted method as the known trusted object used to determine whether or not a given proxy is equivalent in trust, content, and function.

uuid

private final Uuid uuid

The top level Uuid that has been assigned to the Outrigger server this verifier is for.

Constructor Detail

ProxyVerifier

ProxyVerifier(OutriggerServer server,
              Uuid uuid)

Returns a verifier for the smart proxies of an Outrigger server with the specified server reference.

Parameters:

server - the reference to the OutriggerServer.

uuid - the Uuid assigned to the Outrigger server server is a reference to.

Throws:

UnsupportedOperationException - if server does not implement both RemoteMethodControl and TrustEquivalence

NullPointerException - if either argument is null.

Method Detail

isTrustedObject

public boolean isTrustedObject(Object obj,
                               TrustVerifier.Context ctx)
                        throws RemoteException

Returns true if the specified proxy object (that is not yet known to be trusted) is equivalent in trust, content, and function to the canonical server reference this object was constructed with; otherwise returns false.

Specified by:

isTrustedObject in interface TrustVerifier

Parameters:

obj - proxy object that will be compared to this class' stored canonical proxy to determine whether or not the given proxy object is equivalent in trust, content, and function.

ctx - the trust verifier context, to aid in verification of the specified object and its components

Returns:

true if the specified object (that is not yet known to be trusted) is equivalent in trust, content, and function to the canonical inner proxy object referenced in this class; otherwise returns false.

Throws:

NullPointerException - if any argument is null

RemoteException - if a communication-related exception occurs

readObject

private void readObject(ObjectInputStream in)
                 throws IOException,
                        ClassNotFoundException

Verifies that the server reference implements TrustEquivalence.

Throws:

IOException

ClassNotFoundException
