        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
        Parameters:
        input - document input stream, or null
        metadata - input metadata for the document
        Returns:
        detected media type, or application/octet-stream
        Throws:
        IOException - if the document input stream could not be read
