Package org.apache.tika.detect.crypto

Class Pkcs7Detector

java.lang.Object

org.apache.tika.detect.crypto.Pkcs7Detector

All Implemented Interfaces:

Serializable, SelfConfiguring, Detector

public class Pkcs7Detector
extends Object
implements Detector

Optional detector that surfaces the CMS/PKCS7 smime-type at detection time, using the same CmsClassifier as Pkcs7Parser. Marked spi = false so it is NOT auto-loaded (the default detect path stays cheap — magic gives the coarse family and the parser refines the subtype); enable it by name in a tika-config when you need the subtype from detect() without parsing.

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 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:

tis - document input stream, or null

metadata - input metadata for the document

parseContext - the parse context

Returns:

detected media type, or application/octet-stream

Throws:

IOException - if the document input stream could not be read
