Constructor Summary

HTMLDocumentParser()
Creates a new HTMLDocumentParser, without specifying the DocumentIDMap.

HTMLDocumentParser(DocumentIDMapper docIDMap)
Creates a new HTMLDocumentParser with the specified text parser & doc ID mapper.

Method Summary

void	addParsingListener(ParsingListener listener) Adds the specific parsing listener
void	handleEndTag(javax.swing.text.html.HTML.Tag t, int pos) Handles the end of a HTML tag that has some contents (start, some text or other HTML tags, and then an end) and notifies the HTMLParsingListeners and HypertextParsingListeners if it is an anchor tag.
void	handleSimpleTag(javax.swing.text.html.HTML.Tag t, javax.swing.text.MutableAttributeSet a, int pos) Handles a simple HTML tag (just a start & end with no text-node contents) and notifies the HTMLParsingListeners of the tag & position
void	handleStartTag(javax.swing.text.html.HTML.Tag t, javax.swing.text.MutableAttributeSet a, int pos) Handles the start of a HTML tag that has some contents (start, some text or other HTML tags, and then an end) and notifies the HTMLParsingListeners and HypertextParsingListeners if it is an anchor tag.
void	handleText(char[] data, int pos) This method simply delegates the text parsing to the TextDocumentParser.
void	parseDocument(int docID, java.io.Reader documentReader) Parses the document backing this reader
void	removeParsingListener(ParsingListener listener) removes the specified parsing listener
void	setParameter(java.lang.String name, java.lang.Object value) This method configures this parser for various runtime parameters.

Constructor Detail

HTMLDocumentParser

public HTMLDocumentParser(DocumentIDMapper docIDMap)

Creates a new HTMLDocumentParser with the specified text parser & doc ID mapper. Either parameter can be null

HTMLDocumentParser

public HTMLDocumentParser()

Creates a new HTMLDocumentParser, without specifying the DocumentIDMap. Without this map, this parser cannot parse hyperlink information -- that is, it can't resolve linked documents to their ID's.

Method Detail

setParameter

public void setParameter(java.lang.String name,
                         java.lang.Object value)

This method configures this parser for various runtime parameters.

Specified by:
