      • CodespaceRange

        public CodespaceRange​(byte[] startBytes,
                      byte[] endBytes)
        Creates a new instance of CodespaceRange. The length of both arrays has to be the same.
        For one byte ranges startBytes and endBytes define a linear range of values. Double byte values define a rectangular range not a linear range. Examples:
        <00> <20> defines a linear range from 0x00 up to 0x20.
        <8140> to <9FFC> defines a rectangular range. The high byte has to be within 0x81 and 0x9F and the low byte has to be within 0x40 and 0xFC
        Parameters:
        startBytes - start of the range
        endBytes - start of the range

    • Method Detail

      • getCodeLength

        public int getCodeLength()
        Returns the length of the codes of the codespace.
        Returns:
        the code length

      • matches

        public boolean matches​(byte[] code)
        Returns true if the given code bytes match this codespace range.
        Parameters:
        code - the code bytes to be matched
        Returns:
        true if the given code bytes match this codespace range

      • isFullMatch

        public boolean isFullMatch​(byte[] code,
                           int codeLen)
        Returns true if the given number of code bytes match this codespace range.
        Parameters:
        code - the code bytes to be matched
        codeLen - the code length to be used for matching
        Returns:
        true if the given number of code bytes match this codespace range
