I2PSessionDemultiplexer (I2P Anonymous Network - Java Documentation

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.

                             int msgId,

    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 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

```
    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.
