Method Details

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, List 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

Parameters:

word - word to add as an exception

hyphenatedword - pre-hyphenated word

addPattern

             void addPattern
             (String pattern, String values)
            

Add hyphenation patterns.

Parameters:

pattern - the pattern

values - interletter values expressed as a string of digit characters.
