throws ExtractorException
- 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.
