Method Detail

addClass

void addClass(String chargroup)
Add a character class. A character class defines characters that are considered equivalent for the purpose of hyphenation (e.g. "aA"). It usually means to ignore case.

Parameters:
chargroup - character group

addException

void addException(String word,
                  ArrayList<Object> hyphenatedword)
Add a hyphenation exception. An exception replaces the result obtained by the algorithm for cases for which this fails or the user wants to provide his own hyphenation. A hyphenatedword is a vector of alternating String's and Hyphen instances


addPattern

void addPattern(String pattern,
                String values)
Add hyphenation patterns.

Parameters:
pattern - the pattern
values - interletter values expressed as a string of digit characters.
