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
- Following copied from interface:
org.apache.fop.hyphenation.PatternConsumer
- Parameters:
chargroup
- 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
- Following copied from interface:
org.apache.fop.hyphenation.PatternConsumer
- Parameters:
pattern
- the patternvalues
- interletter values expressed as a string of
digit characters.
