Method Detail

openChannel

Cancellable openChannel(Identifier target,
                        Identifier rendezvous,
                        Identifier source,
                        int uid,
                        Continuation<java.lang.Integer,java.lang.Exception> deliverResultToMe,
                        java.util.Map<java.lang.String,java.lang.Object> options)

Calls ChannelOpener.openChannel(dest, credentials) on target Possible exceptions to deliverResultToMe: NodeIsFaultyException if target is faulty UnableToConnectException if dest is faulty Called by: 1) Rendezvous if the target and source are NATted 2) Source if target is NATted, but source isn't Not called if the pilotFinder found a pilot for the target (in FreePastry this means that this will not be called if the target is in the leafSet).

Parameters:

target - call ChannelOpener.openChannel() on this Identifier

rendezvous - pass this to ChannelOpener.openChannel(), it's who the ChannelOpener will connect to

credentials - this is also passed to ChannelOpener.openChannel()

deliverResultToMe - notify me when success/failure

Returns:

a way to cancel the request

sendMessage

MessageRequestHandle<Identifier,java.nio.ByteBuffer> sendMessage(Identifier i,
                                                                 java.nio.ByteBuffer m,
                                                                 MessageCallback<Identifier,java.nio.ByteBuffer> deliverAckToMe,
                                                                 java.util.Map<java.lang.String,java.lang.Object> options)

Sends the message via an out-of-band channel. Usually routing.
