getSupportedTypes

public Set<MediaType> getSupportedTypes(ParseContext context)

Description copied from interface: Parser

Returns the set of media types supported by this parser when used with the given parse context.

Parameters:

context - parse context

Returns:

immutable set of media types

parse

public void parse(InputStream stream,
                  ContentHandler handler,
                  Metadata metadata,
                  ParseContext context)
           throws IOException,
                  SAXException,
                  TikaException

Description copied from interface: Parser

Parses a document stream into a sequence of XHTML SAX events. Fills in related document metadata in the given metadata object.

The given document stream is consumed but not closed by this method. The responsibility to close the stream remains on the caller.

Information about the parsing context can be passed in the context parameter. See the parser implementations for the kinds of context information they expect.

Parameters:

stream - the document stream (input)

handler - handler for the XHTML SAX events (output)

metadata - document metadata (input and output)

context - parse context

Throws:

IOException - if the document stream could not be read

SAXException - if the SAX events could not be processed

TikaException - if the document could not be parsed

Create a OneNoteDocument object.

This won't actually have the binary data of the sections, but it's more of a metadata structure that contains the general structure of the container and contains offset positions of where to find the binary data we care about.

OneNote files are of format:

The header (section 2.3.1 in MS-ONESTORE) is the first 1024 bytes of the file. It contains references to the other structures in the file as well as metadata about the file. The free chunk list (section 2.3.2 in MS-ONESTORE) defines where there are free spaces in the file where data can be written. The transaction log (section 2.3.3 in MS-ONESTORE) stores the state and length of each file node list (section 2.4 in MS-ONESTORE) in the file. The hashed chunk list (section 2.3.4 in MS-ONESTORE) stores read-only objects in the file that can be referenced by multiple revisions (section 2.1.8 in MS-ONESTORE). The root file node list (section 2.1.14 in MS-ONESTORE) is the file node list that is the root of the tree of all file node lists in the file.

In this method we first parse the header.

After parsing the header, this results in header.fcrFileNodeListRoot that points to the first

Parameters:

oneNoteDirectFileResource - A random access file resource used as the source of the content.

Returns:

A parsed one note document. This document does not contain any of the binary data, rather it just contains the data pointers and metadata.

Throws:

IOException - Will throw IOException in typical IO issue situations.
