New Revision: 1195191
URL: http://svn.apache.org/viewvc?rev=1195191&view=rev
Log:
Refactored several of the methods from "SharedDataHelper",
"PropertiesController" and "ParticipantsController" into a single model facade
class, SharedContext, encapsulating the concerns of participants and shared
data. As well as removing some odd dependencies (e.g. between controllers) and
a further abstraction from the persistence layer, this provides a means for
handling storage of shared data differently from other types of data (e.g.
using nosql and/or cloud storage) and I think makes it a bit easier to
understand the Wookie domain model.
