      • getCanonicalClass

        public int getCanonicalClass​(int ch)
        Gets the combining class of a character from the Unicode Character Database.
        Parameters:
        ch - the source character
        Returns:
        value from 0 to 255

      • getPairwiseComposition

        public char getPairwiseComposition​(int first,
                                   int second)
        Returns the composite of the two characters. If the two characters don't combine, returns NOT_COMPOSITE. Only has to worry about BMP characters, since those are the only ones that can ever compose.
        Parameters:
        first - first character (e.g. 'c')
        second - second character (e.g. '�' cedilla)
        Returns:
        composite (e.g. '�')

      • getRecursiveDecomposition

        public void getRecursiveDecomposition​(boolean canonical,
                                      int ch,
                                      FastStringBuffer buffer)
        Gets recursive decomposition of a character from the Unicode Character Database.
        Parameters:
        canonical - If true bit is on in this byte, then selects the recursive canonical decomposition, otherwise selects the recursive compatibility and canonical decomposition.
        ch - the source character
        buffer - buffer to be filled with the decomposition
