Method Details

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
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 characterbuffer
- buffer to be filled with the decomposition
