public class EmailDocumentFormat
extends TextualDocumentFormat

The format of Documents. Subclasses of DocumentFormat know about particular MIME types and how to unpack the information in any markup or formatting they contain into GATE annotations. Each MIME type has its own subclass of DocumentFormat, e.g. XmlDocumentFormat, RtfDocumentFormat, MpegDocumentFormat. These classes register themselves with a static index residing here when they are constructed. Static getDocumentFormat methods can then be used to get the appropriate format class for a particular document.

unpackMarkup

public void unpackMarkup(Document doc)
                  throws DocumentFormatException
Unpack the markup in the document. This converts markup from the native format (e.g. EMAIL) into annotations in GATE format. Uses the markupElementsMap to determine which elements to convert, and what annotation type names to use. It always tryes to parse te doc's content. It doesn't matter if the sourceUrl is null or not.
Overrides:
unpackMarkup in class TextualDocumentFormat
Parameters:
Document - doc The gate document you want to parse.

unpackMarkup

public void unpackMarkup(Document doc,
                         String originalContentFeatureType)
                  throws DocumentFormatException
Unpack the markup in the document. This converts markup from the native format (e.g. EMAIL) into annotations in GATE format. Uses the markupElementsMap to determine which elements to convert, and what annotation type names to use. It uses the same behaviour as unpackMarkup(Document doc); but the document's old content is preserved into a feature attached to the doc.
Overrides:
unpackMarkup in class TextualDocumentFormat
Parameters:
gate.Document - doc The gate document you want to parse and create annotations
String - originalContentFeatureType The name of a feature that will preserve the old content of the document.

init

public Resource init()
              throws ResourceInstantiationException
Initialise this resource, and return it.
Overrides:
init in class TextualDocumentFormat
