Method Detail

openSocket

public SocketRequestHandle<Identifier> openSocket(Identifier i,
                                                  SocketCallback<Identifier> deliverSocketToMe,
                                                  java.util.Map<java.lang.String,java.lang.Object> options)

Description copied from interface: TransportLayer

Open a socket to the Identifier

Specified by:

openSocket in interface TransportLayer<Identifier,java.nio.ByteBuffer>

Parameters:

i - who to open the socket to

deliverSocketToMe - the callback when the socket is opened

options - options on how to open the socket (don't source route, encrypt etc) (may not be respected if layer cannot provide service)

Returns:

an object to cancel opening the socket if it takes to long, or is no longer relevant

sendMessage

public 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)

Description copied from interface: TransportLayer

Send the message to the identifier

Specified by:

sendMessage in interface TransportLayer<Identifier,java.nio.ByteBuffer>

Parameters:

i - the destination

m - the message

deliverAckToMe - layer dependent notification when the message is sent (can indicate placed on the wire, point-to-point acknowledgment, or end-to-end acknowledgement)

options - delivery options (don't source route, encrypt etc) (may not be respected if layer cannot provide service)

Returns:

ability to cancel the message if no longer relevant

getLocalIdentifier

public Identifier getLocalIdentifier()

Description copied from interface: TransportLayer

The local node.

Specified by:

getLocalIdentifier in interface TransportLayer<Identifier,java.nio.ByteBuffer>

Returns:

The local node.

setCallback

public void setCallback(TransportLayerCallback<Identifier,java.nio.ByteBuffer> callback)

Description copied from interface: TransportLayer

Set the callback for incoming sockets/messages

Specified by:

setCallback in interface TransportLayer<Identifier,java.nio.ByteBuffer>

Parameters:

callback - the callback for incoming sockets/messages

setErrorHandler

public void setErrorHandler(ErrorHandler<Identifier> handler)

Description copied from interface: TransportLayer

To be notified of problems not related to an outgoing messaage/socket. Or to be notified if a callback isn't provided.

Specified by:

setErrorHandler in interface TransportLayer<Identifier,java.nio.ByteBuffer>

Parameters:

handler - to be notified of problems not related to a specific messaage/socket.

destroy

public void destroy()

Specified by:

destroy in interface Destructable

acceptMessages

public void acceptMessages(boolean b)

Toggle accepting incoming messages. Useful in flow control if overwhelmed by incoming sockets. Default: true

Specified by:

acceptMessages in interface TransportLayer<Identifier,java.nio.ByteBuffer>

Specified by:

incomingSocket in class Verifier<Identifier>

Throws:

java.io.IOException
