org.apache.tika.detect.zip.DefaultZipContainerDetector
org.apache.tika.detect.zip.StreamingZipContainerDetector
All Implemented Interfaces:

public class StreamingZipContainerDetector extends DefaultZipContainerDetector
Currently only used in tests. Unlike DefaultZipContainerDetector, this will never try to open the File as a ZipFile; this relies solely on streaming detection.

      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
      Overrides:
      detect in class DefaultZipContainerDetector
      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
