    - #### parse

          public void parse(Source src,
                            IFDocumentHandler documentHandler,
                            FOUserAgent userAgent)
                     throws TransformerException,
                            IFException

      Parses an intermediate file and paints it.
      Parameters:
        `src` - the Source instance pointing to the intermediate file
        `documentHandler` - the intermediate format document handler used to process the IF events
        `userAgent` - the user agent
      Throws:
        `TransformerException` - if an error occurs while parsing the area tree XML
        `IFException` - if an IF-related error occurs inside the target document handler

    - #### getContentHandler

          public ContentHandler getContentHandler(IFDocumentHandler documentHandler,
                                                  FOUserAgent userAgent)

      Creates a new ContentHandler instance that you can send the area tree XML to. The parsed pages are added to the AreaTreeModel instance you pass in as a parameter.
      Parameters:
        `documentHandler` - the intermediate format document handler used to process the IF events
        `userAgent` - the user agent
      Returns:
        the ContentHandler instance to receive the SAX stream from the area tree XML
