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

@Deprecated
public void startElement(String tag,
                         HashMap h)

Deprecated.

Called when a start tag is found.

Specified by:

startElement in interface SimpleXMLDocHandler

Parameters:

tag - the tag name

h - the tag's attributes

startElement

public void startElement(String tag,
                         Map<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 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

Parameters:

w - The word to change

e - A vector of alternating String's and Hyphen instances

addPattern

public void addPattern(String p,
                       String v)

Description copied from interface: PatternConsumer

Add hyphenation patterns.

Specified by:
