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,
                                      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
