  • Method Details

    • isValidChar

      public static boolean isValidChar(char ch)
      Determines whether a character can be encoded in Code 128.
      Parameters:
      ch - the character to check
      Returns:
      true if it is a valid character

    • isInCodeSetA

      public static boolean isInCodeSetA(char ch)
      Determines whether a character is defined in codeset A.
      Parameters:
      ch - the character to check
      Returns:
      true if it is found in codeset A

    • isInCodeSetB

      public static boolean isInCodeSetB(char ch)
      Determines whether a character is defined in codeset B.
      Parameters:
      ch - the character to check
      Returns:
      true if it is found in codeset B

    • canBeInCodeSetC

      public static boolean canBeInCodeSetC(char ch, boolean second)
      Determines whether a character is a digit or a function 1 command.
      Parameters:
      ch - the character to check
      second - true if checking the character for the second position in a duo.
      Returns:
      true if the above condition is met

    • symbolCharToString

      public static String symbolCharToString(int index)
      Converts a character set index to a String representation. This is primarily used for debugging purposes.
      Parameters:
      index - the character set index
      Returns:
      the String representation

    • toString

      public static String toString(int[] encodedMsg)
      Converts an encoded Code 128 message into a String for debugging purposes.
      Parameters:
      encodedMsg - the encoded message
      Returns:
      the String representation

    • encodeChar

      protected void encodeChar(ClassicBarcodeLogicHandler logic, int index)
      Encodes a character.
      Parameters:
      logic - LogicHandler to send the barcode events to
      index - index withing the character set of the character to encode

    • encodeStop

      protected void encodeStop(ClassicBarcodeLogicHandler logic)
      Encodes the special stop character.
      Parameters:
      logic - LogicHandler to send the barcode events to

    • getEncoder

      protected Code128Encoder getEncoder()
      Returns the encoder to be used. The encoder is responsible for turning a String message into an array of character set indexes.

      Override this method to supply your own implementation.

      Returns:
      the requested encoder

    • generateBarcodeLogic

      public void generateBarcodeLogic(ClassicBarcodeLogicHandler logic, String msg)
      Generates the barcode logic
      Parameters:
      logic - the logic handler to receive the generated events
      msg - the message to encode
