Interface PatternConsumer

All Known Implementing Classes:
  HyphenationTree, PatternParser

    public interface PatternConsumer

This interface is used to connect the XML pattern file parser to the hyphenation tree. This class has been taken from the Apache FOP project (http://xmlgraphics.apache.org/fop/). They have been slightly modified.

Method Summary
`void` `addClass(String chargroup)` Add a character class.
`void` `addException(String word, ArrayList 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 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.
