jmri.jmrix.loconet
Class LnTrafficRouter

java.lang.Object
  jmri.jmrix.loconet.LnTrafficController
      jmri.jmrix.loconet.LnTrafficRouter

All Implemented Interfaces:

EventListener, LocoNetInterface, LocoNetListener

Direct Known Subclasses:

LnMessageClient

public class LnTrafficRouter
extends LnTrafficController
implements LocoNetListener

Implements a LocoNetInterface by doing a scatter-gather to another, simpler implementation.

This is intended for remote operation, where only one copy of each message should go to/from another node. By putting a LnTrafficRouter implementation at the remote node, all of the routing of messages to multiple consumers can be done without traffic over the connection.

Method Detail

status

public boolean status()

Specified by:

status in interface LocoNetInterface

Specified by:

status in class LnTrafficController

sendLocoNetMessage

public void sendLocoNetMessage(LocoNetMessage m)

Forward a preformatted LocoNetMessage to the actual interface.

Specified by:

sendLocoNetMessage in interface LocoNetInterface

Specified by:

sendLocoNetMessage in class LnTrafficController

Parameters:

m - Message to send; will be updated with CRC

message

public void message(LocoNetMessage m)

Receive a LocoNet message from upstream and forward it to all the local clients.

Specified by:

message in interface LocoNetListener

Parameters:

m - The received LocoNet message. Note that this same object may be presented to multiple users. It should not be modified here.

connect

public void connect(LocoNetInterface i)

Make connection to existing LocoNetInterface object for upstream communication.

Parameters:

i - Interface to be connected

disconnectPort

public void disconnectPort(LocoNetInterface i)

Break connection to upstream LocoNetInterface object. Once broken, attempts to send via "message" member will fail.

Parameters:

i - previously connected interface

isXmtBusy

public boolean isXmtBusy()

Implement abstract method to signal if there's a backlog of information waiting to be sent.

Specified by:

isXmtBusy in class LnTrafficController

Returns:

true if busy, false if nothing waiting to send
