      public BarcodeQRCode(String code, Map<EncodeHintType, Object> hints)
      Creates the QR barcode.
      Parameters:
      code - the text to be encoded
      hints - barcode hints. See #setHints for description.

    • BarcodeQRCode

      public BarcodeQRCode(String content)
      Creates the QR barcode with default error correction level (ErrorCorrectionLevel.L) and default character set (ISO-8859-1).
      Parameters:
      content - the text to be encoded

      public BarcodeQRCode()
      Creates an instance of the BarcodeQRCode class.

  • Method Details

    • getCode

      public String getCode()
      Gets the current data.
      Returns:
      the encoded data

    • setCode

      public void setCode(String code)
      Sets the data to be encoded by the barcode. If not specified in hints otherwise, the character set should be ISO-8859-1.
      Parameters:
      code - The data to encode

    • getHints

      public Map<EncodeHintType, Object> getHints()
      Returns:
      modifiers to change the way the barcode is created.

    • setHints

      public void setHints(Map<EncodeHintType, Object> hints)
      Parameters:
      hints - modifiers to change the way the barcode is created. They can be EncodeHintType.ERROR_CORRECTION and EncodeHintType.CHARACTER_SET. For EncodeHintType.ERROR_CORRECTION the values can be ErrorCorrectionLevel.L, M, Q, H. For EncodeHintType.CHARACTER_SET the values are strings and can be Cp437, Shift_JIS and ISO-8859-1 to ISO-8859-16. You can also use UTF-8, but correct behaviour is not guaranteed as Unicode is not supported in QRCodes. The default value is ISO-8859-1.
