Class MimeExtractor

java.lang.Object
  extended by org.semanticdesktop.aperture.extractor.mime.MimeExtractor
All Implemented Interfaces:
Extractor

Deprecated. Use MimeSubCrawler instead.

public class MimeExtractor
extends Object
implements Extractor

An Extractor implementation for message/rfc822-style messages.

The main purpose of this class is to process mails that are stored as .eml-files, as mails originating from a mail server are typically already completely processed (i.e., a structured DataObject is returned rather than a FileDataObject whose stream has to be processed).

Furthermore, this class can also handle web archives in MHTML style (.mht files), as created by Internet Explorer and Mozilla/Firefox (using the Mozilla Archive Format plugin), which have a similar MIME structure.

Only typical body parts are processed during full-text extraction, (binary) attachments are not handled.

                    Charset charset,

Deprecated. 
Description copied from interface: Extractor
Extracts full-text and metadata from the specified binary stream and stores the extracted information as RDF statements in the specified RDFContainer. The optionally specified Charset and MIME type can be used to direct how the stream should be parsed.

The specified InputStream is expected to already use some kind of buffering so that the Extractors are not required to internally buffer bytes to improve performance.

Specified by:
extract in interface Extractor
Parameters:
id - the URI identifying the object (e.g. a file or web page) from which the stream was obtained. The generated statements should describe this URI.
stream - the InputStream delivering the raw bytes.
charset - the charset in which the inputstream is encoded (optional).
mimeType - the MIME type of the passed stream (optional).
result - the container in which this Extractor can put its created RDF statements.
Throws:
ExtractorException - in case of any error during the extraction process.
