Method Summary

void	addClass(String chargroup) Add a character class.
void	addException(String word, ArrayList<Object> hyphenatedword) Add a hyphenation exception.
void	addPattern(String pattern, String values) Add hyphenation patterns.

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.
