jmri.jmrix.zimo
Class Mx1Packetizer

java.lang.Object
  jmri.jmrix.zimo.Mx1TrafficController
      jmri.jmrix.zimo.Mx1Packetizer

All Implemented Interfaces:

Mx1Interface

public class Mx1Packetizer
extends Mx1TrafficController

Access to Zimo Mx1 messages via stream-based I/O. The "Mx1Interface" * side sends/receives Mx1Message objects. The connection to a Mx1PortController is via a pair of *Streams, which then carry sequences of characters for transmission.

Messages come to this via the main GUI thread, and are forwarded back to listeners in that same thread. Reception and transmission are handled in dedicated threads by RcvHandler and XmtHandler objects. Those are internal classes defined here. The thread priorities are:

• RcvHandler - at highest available priority
• XmtHandler - down one, which is assumed to be above the GUI
• (everything else)

sendMx1Message

public void sendMx1Message(Mx1Message m,
                           Mx1Listener reply)

Forward a preformatted Mx1Message to the actual interface. End of Message is added here, then the message is converted to a byte array and queued for transmission

sendMx1Message in interface Mx1Interface

Specified by:

sendMx1Message in class Mx1TrafficController

Parameters:

m - Message to send; will be updated with CRC

connectPort

public void connectPort(Mx1PortController p)

Make connection to existing Mx1PortController object.

Parameters:

p - Port controller for connected. Save this for a later disconnect call

disconnectPort

public void disconnectPort(Mx1PortController p)

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

Parameters:

p - previously connected port

public void startThreads()

Invoked at startup to start the threads needed here.
