  Overrides:
    `startElement` in class `org.xml.sax.helpers.DefaultHandler`
  Throws:
    `org.xml.sax.SAXException`

### endElement

    public void endElement(java.lang.String uri,

    `org.xml.sax.SAXException`

### addClass

    public void addClass(java.lang.String c)

  For testing purposes only. 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)

  For testing purposes only. 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`
  Parameters:
    `w` - word to add as an exception
    `e` - pre-hyphenated word

### addPattern

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

  For testing purposes only. Add hyphenation patterns.

  Specified by:
    `addPattern` in interface `PatternConsumer`
  Parameters:
    `p` - the pattern
    `v` - interletter values expressed as a string of digit characters.

### setTestOut

    public void setTestOut(java.io.PrintStream testOut)

  Set test out stream.

  Parameters:
    `testOut` - the testOut to set

### closeTestOut

    public void closeTestOut()

  Close test out file.

### main

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

  Main entry point when used as an application.

  Parameters:
    `args` - array of command line arguments
