addClass

public void addClass(java.lang.String c)

Description copied from interface: PatternConsumer

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.

Specified by:

addClass in interface PatternConsumer

Parameters:

c - character group

addException

public void addException(java.lang.String w,
                         java.util.ArrayList e)

Description copied from interface: PatternConsumer

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

Specified by:

addException in interface PatternConsumer

addPattern

public void addPattern(java.lang.String p,
                       java.lang.String v)

Description copied from interface: PatternConsumer

Add hyphenation patterns.

Specified by:

addPattern in interface PatternConsumer

Parameters:

p - the pattern

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

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception

Throws:

java.lang.Exception
