[DL-Learner SVN] SF.net SVN: dl-learner: [230] trunk/src

From: <jen...@us...> - 2007-10-17 10:33:47

Revision: 230
          http://dl-learner.svn.sourceforge.net/dl-learner/?rev=230&view=rev
Author:   jenslehmann
Date:     2007-10-17 03:33:42 -0700 (Wed, 17 Oct 2007)

Log Message:
-----------
- implemented generic access to all available components and configuration options in web service interface => this allows to write completely generic clients (e.g. clients could extend themselves automatically once new components and options become available)
- demo implemented in testnew.php
- improved toString() method for config options
