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

setNodeOfInterest

public void setNodeOfInterest(CbusNode n)

Set the CBUS Node to be used for NV programming

Parameters:

n - a CBUS node

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 CV,
 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:

CV - 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

readCV

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

Perform a CV read in the system-specific manner, and using the specified programming mode, possibly using a hint of the current value to speed up programming.

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

On systems that support it, the startVal is a hint as to what the current value of the CV might be (e.g. the value from the roster). This could be verified immediately in direct byte mode to speed up the read process.

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.

Defaults to the normal read method if not overridden in a specific implementation.

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

Parameters:

CVname - the CV to read

p - the listener that will be notified of the read

startVal - a hint of what the current value might be, or 0

Throws:

ProgrammerException - if unable to communicate

useProgrammer

protected void useProgrammer(ProgListener p)
                      throws ProgrammerException

Throws:

ProgrammerException

message

public void message(CanMessage m)

Called when an outgoing message is sent to the CAN Network. Only listening for frames coming in to JMRI, see CanReply

Specified by:

message in interface CanListener

Parameters:

m - the CanMessage being sent.

reply

public void reply(CanReply m)

Called when an incoming CanFrame is received from the CAN Network.

Specified by:

reply in interface CanListener

Parameters:

m - the CanReply being received.

timeout

protected void timeout()

Internal routine to handle a timeout, should be synchronized! Internal routine to handle a timeout

Specified by:

timeout in class AbstractProgrammer

notifyProgListenerEnd

protected void notifyProgListenerEnd(int value,
 int status)

getConfigurator

public Programmer.Configurator getConfigurator()

Description copied from interface: Programmer

Get the configurator of this programmer.

Specified by:

getConfigurator in interface Programmer

Returns:

the configurator if it exists, otherwise null

dispose

public void dispose()

Description copied from interface: Programmer

Free up system resources. Overriding classes should be capable of this being called multiple times as per the Disposable interface. Called when disposing of a disposable.

Note there are no assurances this method will not be called multiple times against a single instance of this Disposable. It is the responsibility of this Disposable to protect itself and the application from ensuring that calling this method multiple times has no unwanted side effects.

Specified by:

dispose in interface Disposable

Specified by:

dispose in interface Programmer
