Constructor Detail

StatementProtocolImpl

public StatementProtocolImpl(PeerReview<Handle,Identifier> peerreview,
                             ChallengeResponseProtocol<Handle,Identifier> challengeProtocol,
                             PeerInfoStore<Handle,Identifier> infoStore,
                             IdentityTransport<Handle,Identifier> transport)

Method Detail

notifyCertificateAvailable

public void notifyCertificateAvailable(Identifier id)

Called if we have received a certificate for a new nodeID. If any messages in our queue were waiting for this certificate, we may be able to forward them now.

cleanupIncompleteStatements

public void cleanupIncompleteStatements()

If a message hangs around in our queue for too long, we discard it

handleIncomingStatement

public void handleIncomingStatement(Handle source,
                                    Statement<Identifier> statement,
                                    java.util.Map<java.lang.String,java.lang.Object> options)

Incoming ACCUSTION and RESPONSE messages come here first. We check whether we have all the necessary nodeID certificates; if not, we request them from the sender.

Specified by:

handleIncomingStatement in interface StatementProtocol<Handle extends RawSerializable,Identifier extends RawSerializable>

makeProgressOnStatement

public void makeProgressOnStatement(IncompleteStatementInfo<Handle,Identifier> idx)
