OSGi 4.3 capability parser
Hi all,
Does Aries contain a utility class yet to parse OSGi 4.3
Provide-Capability/Require-Capability headers yet? Like for instance
to parse this one (from core 4.3 spec section 3.3.4):
Provide-Capability: «
com.acme.dictionary; from:String=nl; to=de; version:Version=3.4, «
com.acme.dictionary; from:String=de; to=nl; version:Version=4.1, «
com.acme.ip2location;country:List<String>="nl,be,fr,uk";version:Version=1.3,«
com.acme.seps; tokens:List<String>="\\,,;,\\\""
Note the comma's inside the list value and the separators in the
tokens attribute...
If not I'll start something and put it in util...
Cheers,
David

I've enhanced the ManifestHeaderProcessor accordingly in r1204471.
Cheers,

Ah yes, that one looks like a good starting point. If I'm not mistaken
Provide-Capability and Require-Capability have the same format (a
namespace followed by one or more directives or attributes). The
syntax is also enhanced in that it supports various data types for
attributes (String, Version, Long, Double and lists of these). Since
I'll be using this in Aries (in the SPI Fly component) I'll try to
enhance ManifestHeaderProcessor for use with generic capabilities and
requirements. Failing that I'll look at the one in Felix. Thanks for
the help!

Hi David,
Have you tried the ManifestHeaderProcessor? Provide-Capabiliity should behave like an export, Require-Capability like an import. I don't think anything new should need to be added to cope with them specifically.

I don't think it is in Aries utils as yet:).
