New Revision: 1737831
URL: http://svn.apache.org/viewvc?rev=1737831&view=rev
Log:
Very initial version of the Converter Service.
The API comes from OSGi RFC 215 and is ASL-2 licensed. It's included here as
the API is not yet release by OSGi.
The implementation of this service is utterly incomplete. This is just a very
small starting point written by me which can be built out in the Felix codebase.
