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. '�')

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
