Method Detail

parse

public void parse(java.io.Reader reader,
                  org.xml.sax.ContentHandler saxContentHandler)
           throws org.xml.sax.SAXException,
                  java.io.IOException

Perform Swing-HTML-parse-event-to-Sax-event conversion

Throws:

org.xml.sax.SAXException

java.io.IOException

preParse

private void preParse()
               throws org.xml.sax.SAXException

Equivalent to Sax startDocument

Throws:

org.xml.sax.SAXException

postParse

private void postParse()
                throws org.xml.sax.SAXException

Equivalent to Sax endDocument

Throws:

org.xml.sax.SAXException - if any SAXExceptions have occurred during parsing

flush

public void flush()
           throws javax.swing.text.BadLocationException

Swing-HTML-parser template method, no ContentHandler equivalent

Overrides:

flush in class javax.swing.text.html.HTMLEditorKit.ParserCallback

Throws:

javax.swing.text.BadLocationException

handleText

public void handleText(char[] data,
                       int pos)

Equivalent to Sax characters

Overrides:

handleText in class javax.swing.text.html.HTMLEditorKit.ParserCallback

getStartIgnoringClosingSimpleTag

private int getStartIgnoringClosingSimpleTag(char[] data)

Adjusts the start offset into the character array for the fact that the Swing HTML parser doesn't handle simple tags with explicit closing angle brackets e.g. <hr/>

Parameters:

data -

Returns:

offset of actual character data into the array

handleComment

public void handleComment(char[] data,
                          int pos)

Equivalent to Sax LexicalHandler comment method. If the supplied ContentHandler is also an LexicalHandler then the cast will be made and the sax event passed on.

Overrides:

handleComment in class javax.swing.text.html.HTMLEditorKit.ParserCallback

handleStartTag

public void handleStartTag(javax.swing.text.html.HTML.Tag tag,
                           javax.swing.text.MutableAttributeSet attributeSet,
                           int pos)

Equivalent to Sax startElement

Overrides:

handleStartTag in class javax.swing.text.html.HTMLEditorKit.ParserCallback

handleEndTag

public void handleEndTag(javax.swing.text.html.HTML.Tag tag,
                         int pos)

Equivalent to Sax endElement

Overrides:

handleEndTag in class javax.swing.text.html.HTMLEditorKit.ParserCallback

handleSimpleTag

public void handleSimpleTag(javax.swing.text.html.HTML.Tag tag,
                            javax.swing.text.MutableAttributeSet attributeSet,
                            int pos)

Equivalent to Sax startElement plus endElement

Overrides:

handleSimpleTag in class javax.swing.text.html.HTMLEditorKit.ParserCallback

handleError

public void handleError(java.lang.String errorMsg,
                        int pos)

Swing-HTML-parser template method, no ContentHandler equivalent. These errors are generally recoverable, so they are logged.

Overrides:

handleError in class javax.swing.text.html.HTMLEditorKit.ParserCallback

convertToSaxAttributes

private org.xml.sax.Attributes convertToSaxAttributes(javax.swing.text.MutableAttributeSet attributeSet)

Simple conversion method.

Parameters:

attributeSet -

Returns:

Sax CDATA Attributes from the Swing MutableAttributeSet

handleSAXException

private void handleSAXException(org.xml.sax.SAXException e)

Log an error from the ContentHandler for raising post-parse
