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

    • Method Detail

      • getCode

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

      • setCode

        public void setCode​(java.lang.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 java.util.Map<EncodeHintType,​java.lang.Object> getHints()
        Returns:
        modifiers to change the way the barcode is created.

      • setHints

        public void setHints​(java.util.Map<EncodeHintType,​java.lang.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.
