jmri.jmrix.nce
Class NceProgrammer

java.lang.Object
  jmri.jmrix.AbstractProgrammer
      jmri.jmrix.nce.NceProgrammer

All Implemented Interfaces:

EventListener, AbstractMRListener, NceListener, Programmer

Direct Known Subclasses:

NceOpsModeProgrammer

public class NceProgrammer
extends AbstractProgrammer
implements NceListener

Convert the jmri.Programmer interface into commands for the NCE powerstation.

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

NceProgrammer

public NceProgrammer()

Method Detail

setMode

public void setMode(int mode)

Switch to a new programming mode. Note that NCE can only do register and page mode. If you attempt to switch to any others, the new mode will set & notify, then set back to the original. This lets the listeners know that a change happened, and then was undone.

Specified by:

setMode in interface Programmer

Parameters:

mode - The new mode, use values from the jmri.Programmer interface

hasMode

public boolean hasMode(int mode)

Signifies mode's available

Specified by:

hasMode in interface Programmer

Parameters:

mode -

Returns:

True if paged or register mode

getMode

public int getMode()

Description copied from interface: Programmer

Get the current programming mode

Specified by:

getMode in interface Programmer

Returns:

one of the class constants identifying a mode

getCanRead

public boolean getCanRead()

Specified by:

getCanRead in interface Programmer

notifyPropertyChange

protected void notifyPropertyChange(String name,
                                    int oldval,
                                    int newval)

writeCV

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

Description copied from interface: Programmer

Perform a CV write in the system-specific manner, and using the specified programming mode. Note that this returns before the write is complete; you have to provide a ProgListener to hear about completion. The 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

Throws:

ProgrammerException

confirmCV

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

Description copied from interface: Programmer

Confirm the value of a CV using the specified programming mode. On some systems, this is faster than a read. Note that this returns before the confirm is complete; you have to provide a ProgListener to hear about completion. The 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

Throws:

ProgrammerException

readCV

public void readCV(int CV,
                   ProgListener p)
            throws ProgrammerException

Description copied from interface: Programmer

Perform a CV read in the system-specific manner, and using the specified programming mode. Note that this returns before the read is complete; you have to provide a ProgListener to hear about completion. The 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

Throws:

ProgrammerException

useProgrammer

protected void useProgrammer(ProgListener p)
                      throws ProgrammerException

Throws:

ProgrammerException

progTaskStart

protected NceMessage progTaskStart(int mode,
                                   int val,
                                   int cvnum)
                            throws ProgrammerException

Throws:

ProgrammerException

message

public void message(NceMessage m)

Specified by:

message in interface NceListener

reply

public void reply(NceReply m)

Specified by:

reply in interface NceListener

timeout

protected void timeout()

Internal routine to handle a timeout

Specified by:

timeout in class AbstractProgrammer

notifyProgListenerEnd

protected void notifyProgListenerEnd(int value,
                                     int status)

controller
