Class LnHexFilePort

java.lang.Object
  jmri.jmrix.AbstractPortController
      jmri.jmrix.loconet.LnPortController

All Implemented Interfaces:

Runnable, PortAdapter, SerialPortAdapter

public class LnHexFilePort
extends LnPortController
implements Runnable

LnHexFilePort implements a LnPortController via a ASCII-hex input file. See below for the file format There are user-level controls for send next message how long to wait between messages An object of this class should run in a thread of its own so that it can fill the output pipe as needed. The input file is expected to have one message per line. Each line can contain as many bytes as needed, each represented by two Hex characters and separated by a space. Variable whitespace is not (yet) supported

Method Detail

load

public void load(File file)

run

public void run()

Specified by:

run in interface Runnable

setDelay

public void setDelay(int newDelay)

Provide a new message delay value, but don't allow it to go below 2 msec.

getInputStream

public DataInputStream getInputStream()

Specified by:

getInputStream in interface PortAdapter

Specified by:

getInputStream in class LnPortController

getOutputStream

public DataOutputStream getOutputStream()

Specified by:

getOutputStream in interface PortAdapter

Specified by:

getOutputStream in class LnPortController

status

public boolean status()

Description copied from class: LnPortController

Check that this object is ready to operate. This is a question of configuration, not transient hardware status.

Specified by:

status in interface PortAdapter

Specified by:

status in interface SerialPortAdapter

Specified by:

status in class LnPortController

running

public boolean running()

okToSend

public boolean okToSend()

Description copied from class: LnPortController

Can the port accept additional characters? This might go false for short intervals, but it might also stick off if something goes wrong.

Provide a default implementation for the MS100, etc, in which this is _always_ true, as we rely on the queueing in the port itself.

Overrides:

okToSend in class LnPortController

getPortNames

public Vector<String> getPortNames()

Description copied from interface: SerialPortAdapter

Provide a vector of valid port names, each a String.

Specified by:

getPortNames in interface SerialPortAdapter

Overrides:

getPortNames in class AbstractPortController

openPort

public String openPort(String portName,
                       String appName)

Description copied from interface: SerialPortAdapter

Open a specified port. The appname argument is to be provided to the underlying OS during startup so that it can show on status displays, etc

Specified by:

openPort in interface SerialPortAdapter

configure

public void configure()

Description copied from interface: PortAdapter

Configure all of the other jmrix widgets needed to work with this adapter

Specified by:

configure in interface PortAdapter

Specified by:

configure in interface SerialPortAdapter

validBaudRates

public String[] validBaudRates()

Description copied from interface: SerialPortAdapter

Get an array of valid baud rates; used to display valid options.

Specified by:

validBaudRates in interface SerialPortAdapter

instance

public static LnHexFilePort instance()
