Package jmri.jmrix.mrc

Class MrcProgrammer

java.lang.Object

jmri.beans.PropertyChangeSupport

jmri.jmrix.AbstractProgrammer

jmri.jmrix.mrc.MrcProgrammer

All Implemented Interfaces:

PropertyChangeFirer, PropertyChangeProvider, Disposable, MrcTrafficListener, Programmer

Direct Known Subclasses:

MrcOpsModeProgrammer

public class MrcProgrammer
extends AbstractProgrammer
implements MrcTrafficListener

Convert the jmri.Programmer interface into commands for the MRC power house.

This has two states: NOTPROGRAMMING, and COMMANDSENT. The transitions to and from programming mode are now handled in the TrafficController code.

MrcProgrammer

public MrcProgrammer(MrcSystemConnectionMemo memo)

Method Details

getSupportedModes

@Nonnull
public List<ProgrammingMode> getSupportedModes()

Get the list of ProgrammingMode supported by this Programmer. If the order is significant, earlier modes are better. Types implemented here.

Specified by:

getSupportedModes in interface Programmer

Specified by:

getSupportedModes in class AbstractProgrammer

Returns:

the list of supported modes or an empty list

getCanRead

public boolean getCanRead()

Checks the general read capability, regardless of mode Basic implementation. Override this to turn reading on and off globally.

Specified by:

getCanRead in interface Programmer

Overrides:

getCanRead in class AbstractProgrammer

Returns:

true if the programmer is capable of reading; false otherwise

getCanWrite

public boolean getCanWrite()

Checks the general write capability, regardless of mode Basic implementation. Override this to turn writing on and off globally.

Specified by:

getCanWrite in interface Programmer

Overrides:

getCanWrite in class AbstractProgrammer

Returns:

true if the programmer is capable of writing; false otherwise

getCanWrite

public boolean getCanWrite(String cv)

Checks the general write capability, regardless of mode, for a specific address Checks using the current default programming mode. CV1 to 1024 valid

Specified by:

getCanWrite in interface Programmer

Overrides:

getCanWrite in class AbstractProgrammer

Parameters:

cv - the address to write to

Returns:

true if the address can be written to; false otherwise

writeCV

public void writeCV(String CVname,
 int val,
 ProgListener p)
             throws ProgrammerException

Perform a CV write in the system-specific manner, and using the specified programming mode.

Handles a general address space through a String address. Each programmer defines the acceptable formats.

Note that this returns before the write is complete; you have to provide a ProgListener to hear about completion. For simplicity, expect the return to be on the GUI thread.

Exceptions will only be thrown at the start, not during the actual programming sequence. A typical exception would be due to an invalid mode (though that should be prevented earlier)

Specified by:

writeCV in interface Programmer

Specified by:

writeCV in class AbstractProgrammer

Parameters:

CVname - the CV to write

val - the value to write

p - the listener that will be notified of the write

Throws:

ProgrammerException - if unable to communicate

confirmCV

public void confirmCV(String CVname,
 int val,
 ProgListener p)
               throws ProgrammerException

Confirm the value of a CV using the specified programming mode. On some systems, this is faster than a read.

Handles a general address space through a String address. Each programmer defines the acceptable formats.

Note that this returns before the write is complete; you have to provide a ProgListener to hear about completion. For simplicity, expect the return to be on the GUI thread.

Exceptions will only be thrown at the start, not during the actual programming sequence. A typical exception would be due to an invalid mode (though that should be prevented earlier)

Specified by:

confirmCV in interface Programmer

Specified by:

confirmCV in class AbstractProgrammer

Parameters:

CVname - the CV to confirm

val - the value to confirm

p - the listener that will be notified of the confirmation

Throws:

ProgrammerException - if unable to communicate

readCV

public void readCV(String CVname,
 ProgListener p)
            throws ProgrammerException

Perform a CV read in the system-specific manner, and using the specified programming mode.

Handles a general address space through a String address. Each programmer defines the acceptable formats.

Note that this returns before the write is complete; you have to provide a ProgListener to hear about completion. For simplicity, expect the return to be on the GUI thread.

Exceptions will only be thrown at the start, not during the actual programming sequence. A typical exception would be due to an invalid mode (though that should be prevented earlier)

Specified by:

readCV in interface Programmer

Specified by:

readCV in class AbstractProgrammer

Parameters:

CVname - the CV to read

p - the listener that will be notified of the read

Throws:

ProgrammerException - if unable to communicate

useProgrammer

protected void useProgrammer(ProgListener p)
                      throws ProgrammerException

Throws:

ProgrammerException

protected MrcMessage progTaskStart(ProgrammingMode mode,
 int val,
 int cvnum)
                            throws ProgrammerException

Throws:

ProgrammerException
