        CIDRange​(int from,
         int to,
         int unicode,
         int codeLength)
        Constructor.
        Parameters:
        from - start value of COD range
        to - end value of CID range
        unicode - unicode start value
        codeLength - byte length of CID values

    • Method Detail

      • getCodeLength

        public int getCodeLength()
        Returns the byte length of the codes of the CID range.
        Returns:
        the code length

      • map

        public int map​(byte[] bytes)
        Maps the given Unicode character to the corresponding CID in this range.
        Parameters:
        bytes - Unicode character
        Returns:
        corresponding CID, or -1 if the character is out of range

      • map

        public int map​(int code,
               int length)
        Maps the given Unicode character to the corresponding CID in this range.
        Parameters:
        code - Unicode character
        length - origin byte length of the code
        Returns:
        corresponding CID, or -1 if the character is out of range

      • unmap

        public int unmap​(int code)
        Maps the given CID to the corresponding Unicode character in this range.
        Parameters:
        code - CID
        Returns:
        corresponding Unicode character, or -1 if the CID is out of range

      • extend

        public boolean extend​(int newFrom,
                      int newTo,
                      int newCid,
                      int length)
        Check if the given values represent a consecutive range of the given range. If so, extend the given range instead of creating a new one.
        Parameters:
        newFrom - start value of the new range
        newTo - end value of the new range
        newCid - start CID value of the range
        length - byte length of CIDs
        Returns:
        true if the given range was extended
