Method Detail

getSupportedModes

@Nonnull
public java.util.List<ProgrammingMode> getSupportedModes()

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

Specified by:

getSupportedModes in interface Programmer

Specified by:

getSupportedModes in class AbstractProgrammer

Returns:

the list of supported modes or an empty list

writeCV

public void writeCV(java.lang.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(java.lang.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(java.lang.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

progTaskStart

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

Internal method to create the EasyDccMessage for programmer task start.

Parameters:

mode - Programming mode to iniate

val - Value to program

cvnum - CV number to address

Returns:

formatted message for layout

Throws:

ProgrammerException - if programmer or mode not available

message

public void message(EasyDccMessage m)

Specified by:

message in interface EasyDccListener

reply

public void reply(EasyDccReply m)

Specified by:

reply in interface EasyDccListener

timeout

protected void timeout()

Internal routine to handle a timeout, should be synchronized!

Specified by:

timeout in class AbstractProgrammer

cleanup

void cleanup()

Internal method to send a cleanup message (if needed) on timeout.

Here, it sends a request to exit from programming mode. But subclasses, e.g. ops mode, may redefine that.

notifyProgListenerEnd

protected void notifyProgListenerEnd(int value,
                                     int status)
