    • CIDRange

      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 Details

    • 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
