Method Detail

getSupportedModes
@Nonnull public java.util.List<ProgrammingMode> getSupportedModes()
Get the list ofProgrammingMode
supported by this Programmer. If the order is significant, earlier modes are better.- Specified by:
getSupportedModes
in interfaceProgrammer
- Specified by:
getSupportedModes
in classAbstractProgrammer
- Returns:
- the list of supported modes or an empty list
-
getCanRead
public boolean getCanRead(java.lang.String addr)
Checks the general read capability, regardless of mode, for a specific address Checks using the current default programming mode Can we read from a specific CV in the specified mode? Answer may not be correct if the command station type and version sent by the command station mimics one of the known command stations.- Specified by:
getCanRead
in interfaceProgrammer
- Overrides:
getCanRead
in classAbstractProgrammer
- Parameters:
addr
- the address to read- Returns:
- true if the address can be read; false otherwise
-
getCanWrite
public boolean getCanWrite(java.lang.String addr)
Checks the general write capability, regardless of mode, for a specific address Checks using the current default programming mode. Can we write to a specific CV in the specified mode? Answer may not be correct if the command station type and version sent by the command station mimics one of the known command stations.- Specified by:
getCanWrite
in interfaceProgrammer
- Overrides:
getCanWrite
in classAbstractProgrammer
- Parameters:
addr
- the address to write to- Returns:
- true if the address can be written to; false otherwise
-
getWriteConfirmMode
@Nonnull public Programmer.WriteConfirmMode getWriteConfirmMode(java.lang.String addr)
Learn about whether the programmer does any kind of verification of write operations By default, say that no verification is done.- Specified by:
getWriteConfirmMode
in interfaceProgrammer
- Overrides:
getWriteConfirmMode
in classAbstractProgrammer
- Parameters:
addr
- A CV address to check (in case this varies with CV range) or null for any- Returns:
- Always WriteConfirmMode.NotVerified
-
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 interfaceProgrammer
- Specified by:
writeCV
in classAbstractProgrammer
- Parameters:
CVname
- the CV to writeval
- the value to writep
- 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 interfaceProgrammer
- Specified by:
confirmCV
in classAbstractProgrammer
- Parameters:
CV
- the CV to confirmval
- the value to confirmp
- 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 interfaceProgrammer
- Specified by:
readCV
in classAbstractProgrammer
- Parameters:
CVname
- the CV to readp
- 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 interfaceProgrammer
- Parameters:
CVname
- the CV to readp
- the listener that will be notified of the readstartVal
- 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(DCCppReply m)
Member function that will be invoked by a DCCppInterface implementation to forward a DCC++ message from the layout.- Specified by:
message
in interfaceDCCppListener
- Parameters:

- The received DCC++ message. Note that this same object may be presented to multiple users. It should not be modified here.
-
message
public void message(DCCppMessage l)
Member function that will be invoked by a DCCppInterface implementation to forward a DCC++ message sent to the layout. Normally, this function will do nothing.- Specified by:
message
in interfaceDCCppListener
- Parameters:
l
- The received DCC++ message. Note that this same object may be presented to multiple users. It should not be modified here.

public void notifyTimeout(DCCppMessage msg)
Description copied from interface:DCCppListener
Member function invoked by an DCCppInterface implementation to notify a sender that an outgoing message timed out and was dropped from the queue.- Specified by:
notifyTimeout
in interfaceDCCppListener
- Parameters:
msg
- the message that timed out.
-
programmerBusy
public boolean programmerBusy()

controller
protected DCCppTrafficController controller()
-
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 theDisposable
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.
