Constructor Summary

Constructors

Constructor and Description
ProxyVerifier(Fiddler innerProxy, Uuid proxyID) Constructs an instance of TrustVerifier that can be used to determine whether or not a given proxy is equivalent in trust, content, and function to the service's innerProxy referenced in the class constructed here.

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 inner proxy object referenced in this class; otherwise returns false.

Constant Field Values

innerProxy

private final RemoteMethodControl innerProxy

The canonical instance of the inner proxy to the service. 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.

proxyID

private final Uuid proxyID

The unique identifier associated with the backend server referenced by the innerProxy, used for comparison with the IDs extracted from the smart proxies being verified.

Constructor Detail

ProxyVerifier

ProxyVerifier(Fiddler innerProxy,
              Uuid proxyID)

Constructs an instance of TrustVerifier that can be used to determine whether or not a given proxy is equivalent in trust, content, and function to the service's innerProxy referenced in the class constructed here.

Parameters:

innerProxy - canonical instance of the inner proxy to the service. The isTrustedObject method will determine whether or not proxies input to that method are equivalent in trust, content, and function to this object.

proxyID - instance of Uuid containing the unique identifier associated with the backend server referenced by the innerProxy paramater.

Throws:

UnsupportedOperationException - if innerProxy does not implement both RemoteMethodControl and TrustEquivalence

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 inner proxy object referenced in this class; 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
