SprogProgrammer

public SprogProgrammer(SprogSystemConnectionMemo memo)

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. Implemented Types.

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

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

readCV

public void readCV(java.lang.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
