    • setMarkLimit

      @Field public void setMarkLimit(int markLimit)
      If this is less than 0 and a TikaInputStream is used, the file will be spooled to disk, and detection will run on the full file.

      If this is greater than 0 and a TikaInputStream is used, this will try detection on the stream up to the markLimit, and if that is greater than the length of the file, the streaming result will be returned. If the BoundedInputStream hits its bound during detection, the file will be spooled to disk, and detection will be run on the full file.

      If a non-TikaInputStream is used, detection will only work up to the markLimit, potentially leading to lack of precision in zip-based file detection.

      Parameters:
      markLimit - mark limit for streaming detection

    • getMarkLimit

      public int getMarkLimit()

    • detect

      public MediaType detect(InputStream input, Metadata metadata) throws IOException
      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
