Subject svn commit: r678082 - in /portals/jetspeed-2/portal/branches/JS2-869/jetspeed-api/src/main/java/org/apache/jetspeed: attribute/ security/
Date Sat, 19 Jul 2008 00:23:57 GMT
Author: ate
Date: Fri Jul 18 17:23:57 2008
New Revision: 678082

URL: http://svn.apache.org/viewvc?rev=678082&view=rev
Log:
first draft proposal for a new "GenericAttributes" model which might be feasible to use for
Security entity (Role/Group/User) attributes.
As an example, I've also added a new JetspeedPrincipal interface which could be used as base
interface for our current Role,Group and User interfaces (when we drop their Preferences access).

Please note: the GenericAttributes model is far for complete or anywhere definitive, just
the outcome of a quick and dirty braindump of what I could think of as possible solution...
