Package jmri.implementation

Class OpsModeDelayedProgrammerFacade

java.lang.Object

jmri.jmrix.AbstractProgrammerFacade

jmri.implementation.OpsModeDelayedProgrammerFacade

All Implemented Interfaces:

java.util.EventListener, Disposable, ProgListener, Programmer

public class OpsModeDelayedProgrammerFacade
extends AbstractProgrammerFacade
implements ProgListener

Programmer facade for access to Accessory Decoder Ops Mode programming

(Eventually implements four modes, passing all others to underlying programmer:

• OPSACCBYTEMODE
• OPSACCBITMODE
• OPSACCEXTBYTEMODE
• OPSACCEXTBITMODE

Used through the String write/read/confirm interface. Accepts integers as addresses, but then emits NMRA DCC packets through the default CommandStation interface (which must be present)

Constructor Detail

OpsModeDelayedProgrammerFacade

public OpsModeDelayedProgrammerFacade(Programmer prog,
                                      int writeDelay)

Programmer facade for access to Accessory Decoder Ops Mode programming.

Parameters:

prog - The Ops Mode Programmer we are piggybacking on.

writeDelay - A string representing the desired delay after a write operation, in milliseconds.

Method Detail

writeCV

public void writeCV(java.lang.String cv,
                    int val,
                    ProgListener p)
             throws ProgrammerException

Description copied from class: AbstractProgrammerFacade

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

Overrides:

writeCV in class AbstractProgrammerFacade

Parameters:

cv - 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

readCV

public void readCV(java.lang.String cv,
                   ProgListener p)
            throws ProgrammerException

Description copied from class: AbstractProgrammerFacade

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

Overrides:

readCV in class AbstractProgrammerFacade

Parameters:

cv - 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 cv,
                   ProgListener p,
                   int startVal)
            throws ProgrammerException

Description copied from interface: Programmer

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:

cv - 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

confirmCV

public void confirmCV(java.lang.String cv,
                      int val,
                      ProgListener p)
               throws ProgrammerException

Description copied from class: AbstractProgrammerFacade

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

Overrides:

confirmCV in class AbstractProgrammerFacade

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

useProgrammer

protected void useProgrammer(ProgListener p)
                      throws ProgrammerException

Internal method to remember who's using the programmer.

Parameters:

p - the programmer

Throws:

ProgrammerException - if p is already in use

programmingOpReply

public void programmingOpReply(int value,
                               int status)

Description copied from interface: ProgListener

Receive a callback at the end of a programming operation.

Specified by:

programmingOpReply in interface ProgListener

Parameters:

value - Value from a read operation, or value written on a write

status - Denotes the completion code. Note that this is a bitwise combination of the various status coded defined in this interface.
