Method Detail

parse

public void parse(InputStream stream,
                  PatternConsumer consumer)

getPattern

protected static String getPattern(String word)

normalizeException

protected ArrayList<Object> normalizeException(ArrayList<Object> ex)

getExceptionWord

protected String getExceptionWord(ArrayList<Object> ex)

getInterletterValues

protected static String getInterletterValues(String pat)

endDocument

public void endDocument()
Description copied from interface: SimpleXMLDocHandler
Called after the document is parsed.

Specified by:
endDocument in interface SimpleXMLDocHandler

endElement

public void endElement(String tag)
Description copied from interface: SimpleXMLDocHandler
Called when an end tag is found.

Specified by:
endElement in interface SimpleXMLDocHandler
Parameters:
tag - the tag name

startDocument

public void startDocument()
Description copied from interface: SimpleXMLDocHandler
Called when the document starts to be parsed.

Specified by:
startDocument in interface SimpleXMLDocHandler

startElement

public void startElement(String tag,
                         HashMap<String,String> h)
Description copied from interface: SimpleXMLDocHandler
Called when a start tag is found.

Specified by:
startElement in interface SimpleXMLDocHandler
Parameters:
tag - the tag name
h - the tag's attributes

text

public void text(String str)
Description copied from interface: SimpleXMLDocHandler
Called when a text element is found.

Specified by:
text in interface SimpleXMLDocHandler
Parameters:
str - the text element, probably a fragment.

addClass

public void addClass(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(String w,
                         ArrayList<Object> 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(String p,
                       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(String[] args)
                 throws Exception
Throws:
Exception
