public MediaType detect( input,
                        Metadata metadata)
Description copied from interface: Detector
Detects the content type of the given input document. Returns application/octet-stream if the type of the document can not be detected.

If the document input stream is not available, then the first argument may be null. Otherwise the detector may read bytes from the start of the stream to help in type detection. The given stream is guaranteed to support the mark feature and the detector is expected to mark the stream before reading any bytes from it, and to reset the stream before returning. The stream must not be closed by the detector.

The given input metadata is only read, not modified, by the detector.

Specified by:
detect in interface Detector
input - document input stream, or null
metadata - input metadata for the document
detected media type, or application/octet-stream
Throws: - if the document input stream could not be read
