Class I2PSessionDemultiplexer

java.lang.Object

net.i2p.client.impl.I2PSessionDemultiplexer

All Implemented Interfaces:

I2PSessionListener, I2PSessionMuxedListener

public class I2PSessionDemultiplexer
extends Object
implements I2PSessionMuxedListener

Implement multiplexing with a 1-byte 'protocol' and a two-byte 'port'. Listeners register with either addListener() or addMuxedListener(), depending on whether they want to hear about the protocol, from port, and to port for every received message. messageAvailable() only calls one listener, not all that apply. The others call all listeners.

void	disconnected(I2PSession session) Notify the client that the session has been terminated.
void	errorOccurred(I2PSession session, String message, Throwable error) Notify the client that some error occurred.
void	messageAvailable(I2PSession session, int msgId, long size) unused
void	messageAvailable(I2PSession session, int msgId, long size, int proto, int fromport, int toport) Instruct the client that the given session has received a message Will be called only if you register via addMuxedSessionListener().
static String	protocolNumberToString(int proto)
void	removeListener(int proto, int port)
void	reportAbuse(I2PSession session, int severity) Instruct the client that the session specified seems to be under attack and that the client may wish to move its destination to another router.

addListener

public void addListener(I2PSessionListener l,
                        int proto,
                        int port)

addMuxedListener

public void addMuxedListener(I2PSessionMuxedListener l,
                             int proto,
                             int port)

For those that do care UDP perhaps

disconnected

public void disconnected(I2PSession session)

Description copied from interface: I2PSessionMuxedListener

Notify the client that the session has been terminated. All registered listeners will be called.

Specified by:

disconnected in interface I2PSessionListener

Specified by:

disconnected in interface I2PSessionMuxedListener

errorOccurred

public void errorOccurred(I2PSession session,
                          String message,
                          Throwable error)

Description copied from interface: I2PSessionMuxedListener

Notify the client that some error occurred. All registered listeners will be called.

Specified by:

errorOccurred in interface I2PSessionListener

Specified by:

errorOccurred in interface I2PSessionMuxedListener

error - can be null? or not?

messageAvailable

public void messageAvailable(I2PSession session,
                             int msgId,
                             long size)

unused

Specified by:

messageAvailable in interface I2PSessionListener

Specified by:

messageAvailable in interface I2PSessionMuxedListener

Parameters:

session - session to notify

msgId - message number available

size - size of the message - why it's a long and not an int is a mystery

messageAvailable

public void messageAvailable(I2PSession session,
                             int msgId,
                             long size,
                             int proto,
                             int fromport,
                             int toport)

Description copied from interface: I2PSessionMuxedListener

Instruct the client that the given session has received a message Will be called only if you register via addMuxedSessionListener(). Will be called only for the proto(s) and toport(s) you register for. After this is called, the client should call receiveMessage(msgId). There is currently no method for the client to reject the message. If the client does not call receiveMessage() within a timeout period (currently 30 seconds), the session will delete the message and log an error. Only one listener is called for a given message, even if more than one have registered. See I2PSessionDemultiplexer for details.

Specified by:

messageAvailable in interface I2PSessionMuxedListener

Parameters:

session - session to notify

msgId - message number available

size - size of the message - why it's a long and not an int is a mystery

proto - 1-254 or 0 for unspecified

fromport - 1-65535 or 0 for unspecified

toport - 1-65535 or 0 for unspecified

protocolNumberToString

public static String protocolNumberToString(int proto)

removeListener

public void removeListener(int proto,
                           int port)

reportAbuse

public void reportAbuse(I2PSession session,
                        int severity)

Description copied from interface: I2PSessionMuxedListener

Instruct the client that the session specified seems to be under attack and that the client may wish to move its destination to another router. All registered listeners will be called. Unused. Not fully implemented.

Specified by:

reportAbuse in interface I2PSessionListener

Specified by:

reportAbuse in interface I2PSessionMuxedListener

Parameters:
