Class SpeedoTrafficController

Show UML class diagram

java.lang.Object
  jmri.jmrix.bachrus.SpeedoTrafficController

All Implemented Interfaces:

SerialPortEventListener, EventListener, SpeedoInterface

public class SpeedoTrafficController
extends Object
implements SpeedoInterface, SerialPortEventListener

Converts Stream-based I/O to/from speedo messages. The "SpeedoInterface" side sends/receives message objects. The connection to a SpeedoPortController is via a pair of *Streams, which then carry sequences of characters for transmission. Note that this processing is handled in an independent thread. Updated January 2010 for gnu io (RXTX) - Andrew Berridge. Comments tagged with "AJB" indicate changes or observations by me Removed Runnable implementation and methods for it

Constructor Detail

SpeedoTrafficController

public SpeedoTrafficController()

Method Detail

status

public boolean status()

Description copied from interface: SpeedoInterface

Test operational status of interface.

Specified by:

status in interface SpeedoInterface

Returns:

true is interface implementation is operational.

addSpeedoListener

public void addSpeedoListener(SpeedoListener l)

Specified by:

addSpeedoListener in interface SpeedoInterface

removeSpeedoListener

public void removeSpeedoListener(SpeedoListener l)

Specified by:

removeSpeedoListener in interface SpeedoInterface

notifyReply

protected void notifyReply(SpeedoReply r)

connectPort

public void connectPort(SpeedoPortController p)

Make connection to existing PortController object.

disconnectPort

public void disconnectPort(SpeedoPortController p)

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

instance

public static SpeedoTrafficController instance()

static function returning the SpeedoTrafficController instance to use.

Returns:

The registered SpeedoTrafficController instance for general use, if need be creating one.

endReply

boolean endReply(SpeedoReply msg)

serialEvent

public void serialEvent(SerialPortEvent event)

serialEvent - respond to an event triggered by RXTX. In this case we are only dealing with DATA_AVAILABLE but the other events are left here for reference. AJB Jan 2010

Specified by:

serialEvent in interface SerialPortEventListener
