    • getPermission

    • writeCV

      public void writeCV(String CV, 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
      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(String CV, 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
      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(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
    • confirmCV

      public void confirmCV(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
      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
    • 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
      Returns:
      the list of supported modes or an empty list
    • setMode

      public void setMode(ProgrammingMode p)
      Set the programmer to a particular mode.

      Mode is a bound parameter; mode changes fire listeners.

      Only modes returned by Programmer.getSupportedModes() are supported. If an invalid mode is requested, the active mode is unchanged.

      Specified by:
      setMode in interface Programmer
      Parameters:
      p - a valid node returned by Programmer.getSupportedModes() or null; null is ignored if Programmer.getSupportedModes() is not empty
    • getMode

      Get the current programming mode
      Specified by:
      getMode in interface Programmer
      Returns:
      the current mode or null if none is defined and no default mode is defined

      Specified by:
      getCanRead in interface Programmer
      Returns:
      true if the programmer is capable of reading; false otherwise
    • getCanRead

      public boolean getCanRead(String addr)
