Constructor Detail

XNetOpsModeProgrammer

public XNetOpsModeProgrammer(int pAddress,
                             XNetTrafficController controller)

Method Detail

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) Send an ops-mode write request to the Xpressnet.

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

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

confirmCV

public void confirmCV(java.lang.String CVname,
                      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:

CVname - 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

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. 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

getCanRead

public boolean getCanRead()

Checks the general read capability, regardless of mode Basic implementation. Override this to turn reading on and off globally. Can this ops-mode programmer read back values? Indirectly we can, though this requires an external display (a Lenz LRC120) and enabling railcom.

Specified by:

getCanRead in interface Programmer

Overrides:

getCanRead in class AbstractProgrammer

Returns:

true to allow us to trigger an ops mode read

message

public void message(XNetReply l)

Member function that will be invoked by an XNetInterface implementation to forward an XNet message from the layout.

Specified by:

message in interface XNetListener

Parameters:

l - The received XNet message. Note that this same object may be presented to multiple users. It should not be modified here.

getLongAddress

public boolean getLongAddress()

Specified by:

getLongAddress in interface AddressedProgrammer

getAddressNumber

public int getAddressNumber()

Specified by:

getAddressNumber in interface AddressedProgrammer

getAddress

public java.lang.String getAddress()

Specified by:

getAddress in interface AddressedProgrammer

message

public void message(XNetMessage l)

Member function that will be invoked by an XNetInterface implementation to forward an XNet message sent to the layout. Normally, this function will do nothing.

Specified by:

message in interface XNetListener

Parameters:

l - The received XNet message. Note that this same object may be presented to multiple users. It should not be modified here.

notifyTimeout

public void notifyTimeout(XNetMessage msg)

Member function invoked by an XNetInterface implementation to notify a sender that an outgoing message timed out and was dropped from the queue. Handle a timeout notification

Specified by:

notifyTimeout in interface XNetListener

Parameters:

msg - message which has timed out.

timeout

protected void timeout()

Internal routine to handle a timeout, should be synchronized!

Specified by:

timeout in class AbstractProgrammer

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
