Nick Burch commented on TIKA-509:
---------------------------------
Initial work committed in r995157.
This commit shows a rough cut of the interfaces and key classes, so everyone
can review them now there's some concrete code to look at. One change required
though is to not pass an open inputstream in for every firing of the handler.
Instead, the handler should be given a chance to decline the embeded resource
first, before the extractor potentially does lots of work to generate/unpack
the resource
Also in the commit is a basic POIFS extractor. It only does nested embeded
office files, no images, and only for word+excel. However, it should give an
idea of how things may work
The config for the auto-detector isn't wired in yet, that'll be done once we
have further extractors.

> Key: TIKA-509
> URL: https://issues.apache.org/jira/browse/TIKA-509
> Project: Tika
> Issue Type: New Feature
> Components: parser
> Affects Versions: 0.7
> Reporter: Nick Burch
> Assignee: Nick Burch
> Priority: Minor
>
> As discussed on the mailing list:
> http://mail-archives.apache.org/mod_mbox/tika-dev/201009.mbox/%3calpine.deb.1.10.1009010000250.5...@urchin.earth.li%3e
> This service will operate in a push mode, using streaming where possible (not
> all container formats will support that). Users can control recursion, and
> will be given the chance to process each embeded file in turn. It's up to
> them if they process a file or skip it.
> It will work similar to the current Parser code, with each container having
> its own extractor in the parsers package, and the interface defined in the
> core package. There will be an Auto extractor in the core package, configured
> with a list of parser extractors just like AutoDetectParser does.
