Field Detail

### NOT_COMPOSITE

    public static final int NOT_COMPOSITE

  Constant for use in getPairwiseComposition

    Constant Field Values

Method Detail

### 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. 'ç')

### getRecursiveDecomposition

    public void getRecursiveDecomposition(boolean canonical,
                                          int ch,
                                          java.lang.StringBuffer 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
