Constructor Detail

LandlordProxyVerifier

public LandlordProxyVerifier(Landlord landlord,
                             Uuid landlordUuid)

Returns a verifier for the proxies defined in the landlord package with the specified server reference and server Uuid.

Parameters:

landlord - the reference to the Landlord being used by the leases for communication back to the server.

landlordUuid - a universally unique id that has been assigned to the server granting of the lease. Ideally the Uuid landlord.getUuid would return if landlord implemented ReferentUuid. Used to determine when two leases can be batched together.

Throws:

UnsupportedOperationException - if landlord 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's 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
