public class TextualDocumentFormat
extends DocumentFormat

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.

init

public Resource init()
              throws ResourceInstantiationException

Overrides:
init in class AbstractResource

unpackMarkup

public void unpackMarkup(Document doc)
                  throws DocumentFormatException
Unpack the markup in the document. This converts markup from the native format (e.g. XML, RTF) into annotations in GATE format. Uses the markupElementsMap to determine which elements to convert, and what annotation type names to use.
Overrides:
unpackMarkup in class DocumentFormat

unpackMarkup

public void unpackMarkup(Document doc,
                         String originalContentFeatureType)
                  throws DocumentFormatException
Description copied from class: DocumentFormat
Unpack the markup in the document. This converts markup from the native format (e.g. XML, RTF) into annotations in GATE format. Uses the markupElementsMap to determine which elements to convert, and what annotation type names to use.
Overrides:
unpackMarkup in class DocumentFormat

getDataStore

public DataStore getDataStore()
Description copied from interface: LanguageResource
Get the data store that this LR lives in. Null for transient LRs.
Overrides:
getDataStore in class AbstractLanguageResource
