Nick Burch commented on TIKA-1120:
----------------------------------
The latest detection documentation is at
<https://tika.apache.org/1.3/detection.html> - the URL you referenced is for an
older version of Tika
I don't think people probably should be doing the things in your code... You
should really be going to a TikaConfig object
<http://tika.apache.org/1.3/api/org/apache/tika/config/TikaConfig.html>, and
either getting a Detector from that, or the mime types registry.
Are you able to suggest some tweaks to the most recent documentation that would
make this clearer for someone in your situation?
> Enable direct use of org.apache.tika.mime.MediaType.detect(...)

> Key: TIKA-1120
> URL: https://issues.apache.org/jira/browse/TIKA-1120
> Project: Tika
> Issue Type: Wish
> Components: mime
> Affects Versions: 1.3
> Reporter: Oliver Kopp
> Priority: Minor
>
> When using mime type detection, the classes allow following use:
> try (InputStream is = theInputStream;
> BufferedInputStream bis = new BufferedInputStream(is);) {
> MimeTypes mt = new MimeTypes();
> Metadata md = new Metadata();
> md.add(Metadata.RESOURCE_NAME_KEY, theFileName);
> MediaType mediaType = mt.detect(bis, null);
> return mediaType.toString();
> }
> When debugging this, the MimeTypes class instantiates its internal patterns
> with an empty MediaTypeRegistry. Therefore, getDefaultMimeTypes() is never
> called and thus tika-mimetypes.xml never read.
> Is it possible to enable direct usage of MediaType.detect()? Like adding a
> new constructor, where the MediaTypeRegistry can be set?
> If not, the code comments (or the documentation at
> https://tika.apache.org/0.10/detection.html) should point out that
> MimeTypes() should not instantiated directly for mime type detection, but the
> detectors should be used. Possibly, a minimum example should be added to make
> the usage clear.
> Following example works here
> try (InputStream is = theInputStream;
> BufferedInputStream bis = new BufferedInputStream(is);) {
> AutoDetectParser parser = new AutoDetectParser();
> Detector detector = parser.getDetector();
> Metadata md = new Metadata();
> md.add(Metadata.RESOURCE_NAME_KEY, theFileName);
> MediaType mediaType = detector.detect(bis, md);
> return mediaType.toString();
> }
