Sample code use to parse

TikaInputStream tikaStream = TikaInputStream.get(stream);
    TikaResultWrapper result;
    try {
      long streamSize = tikaStream.getLength();
      Metadata metadata =
        constructMetadata(fileName, mimeType, streamSize);
      if (streamSize < maxFileSize) {
        SamplingSaxHandler handler =
          new SamplingSaxHandler(samplingSize, metadata);
        handler.setBufferLimit(bufferSize);
        parser.parse(tikaStream, handler, metadata, new ParseContext());
        result = handler.getResult();
      } else {
        result = new TikaResultWrapper(null, metadata);
      }
    } finally {
      tikaStream.close();
