Package jmri.jmrix.rps.serial

Class SerialAdapter

java.lang.Object

jmri.jmrix.AbstractPortController

jmri.jmrix.AbstractSerialPortController

jmri.jmrix.rps.serial.SerialAdapter

All Implemented Interfaces:

PortAdapter, SerialPortAdapter

public class SerialAdapter
extends AbstractSerialPortController

Implements SerialPortAdapter for the RPS system.

Unlike many other SerialPortAdapters, this also converts the input stream into Readings that can be passed to the Distributor.

This version expects that the "A" command will send back "DATA,," followed by a list of receivers numbers, and data lines will be "0,0,0,0": A value for each address up to the max receiver, even if some are missing (0 in that case)

Constructor Details

SerialAdapter

public SerialAdapter()

Method Details

getSystemConnectionMemo

public RpsSystemConnectionMemo getSystemConnectionMemo()

Get the SystemConnectionMemo associated with this object.

This method should only be overridden to ensure that a specific subclass of SystemConnectionMemo is returned. The recommended pattern is: public MySystemConnectionMemo getSystemConnectionMemo() { return (MySystemConnectionMemo) super.getSystemConnectionMemo(); }

Specified by:

getSystemConnectionMemo in interface PortAdapter

Overrides:

getSystemConnectionMemo in class AbstractPortController

Returns:

the currently associated SystemConnectionMemo

configure

public void configure()

Set up all of the other objects to operate.

openPort

public String openPort(String portName,
 String appName)

Description copied from interface: SerialPortAdapter

Open a specified port.

Parameters:

portName - name tu use for this port

appName - provided to the underlying OS during startup so that it can show on status displays, etc.

Returns:

null indicates OK return, else error message.

sendBytes

void sendBytes(byte[] bytes)

Send output bytes, e.g. characters controlling operation, with small delays between the characters. This is used to reduce overrrun problems.

Parameters:

bytes - Array of characters to be sent one at a time

status

public boolean status()

Description copied from class: AbstractPortController

Query the status of this connection. This is a question of configuration, not transient hardware status.

Specified by:

status in interface PortAdapter

Specified by:

status in interface SerialPortAdapter

Overrides:

status in class AbstractPortController

Returns:

true if OK, at least as far as known

validBaudRates

public String[] validBaudRates()

Get an array of valid baud rate strings; used to display valid options in Connections Preferences.

Specified by:

validBaudRates in interface SerialPortAdapter

Overrides:

validBaudRates in class AbstractSerialPortController

Returns:

array of I18N display strings of port speed settings valid for this serial adapter, must match order and values from SerialPortAdapter.validBaudNumbers()

validBaudNumbers

public int[] validBaudNumbers()

Get an array of valid baud rate numbers; used to store/load adapter speed option.

Specified by:

validBaudNumbers in interface SerialPortAdapter

Overrides:

validBaudNumbers in class AbstractSerialPortController

Returns:

integer array of speeds, must match order and values from SerialPortAdapter.validBaudRates()

defaultBaudIndex

public int defaultBaudIndex()

Description copied from interface: SerialPortAdapter

Get the index of the default port speed for this adapter from the validSpeeds and validRates arrays.

Specified by:

defaultBaudIndex in interface SerialPortAdapter

Overrides:

defaultBaudIndex in class AbstractSerialPortController

Returns:

-1 to indicate not supported, unless overridden in adapter

configureOption1

public void configureOption1(String value)

Set the second port option.

Specified by:

configureOption1 in interface PortAdapter

Specified by:

configureOption1 in interface SerialPortAdapter

Overrides:

configureOption1 in class AbstractPortController

Parameters:

value - to set the option to

nextLine

@InvokeOnGuiThread
protected void nextLine(String s)

Handle a new line from the device.

This needs to execute on the Swing GUI thread. It forwards via the Distributor object.

Parameters:

s - The new message to distribute

setReceivers

void setReceivers(String s)

Handle the message which lists the receiver numbers. Just makes an array of those, which is not actually used.

Parameters:

s - Input line

makeReading

Reading makeReading(String s)
             throws IOException

Convert input line to Reading object.

Parameters:

s - The line of input

Returns:

A Reading object with content parsed from the input line

Throws:

IOException - from underlying I/O
