      • detect

        public static org.apache.tika.mime.MediaType detect​(Set<String> anyCaseNames,
                                                            org.apache.poi.poifs.filesystem.DirectoryEntry root)
        Internal detection of the specific kind of OLE2 document, based on the names of the top-level streams within the file. In some cases the detection may need access to the root DirectoryEntry of that file for best results. The entry can be given as a second, optional argument.

        Following 2.6.1 of MS-CFB , The detection is performed on case insensitive entry names.

        Parameters:
        anyCaseNames -
        root -
        Returns:
      • setMarkLimit

        public void setMarkLimit​(int markLimit)
        If a TikaInputStream is passed in to detect(InputStream, Metadata), and there is not an underlying file, this detector will spool up to markLimit to disk. If the stream was read in entirety (e.g. the spooled file is not truncated), this detector will open the file with POI and perform detection. If the spooled file is truncated, the detector will return OLE (or MediaType.OCTET_STREAM if there's no OLE header).

        As of Tika 1.21, this detector respects the legacy behavior of not performing detection on a non-TikaInputStream.

        Parameters:
        markLimit -
