Description

Mock/Test/Debugging Implementation of the config rules system.

Instead of actually parsing/analysing/resolving queries, this implementation uses a Table of hard wired queries together with preconfigured object instances as answer values. As of 1/2008 it is used to "keep the implementation work going" – later on, when we use a real Prolog interpreter, it still may be useful for testing and debugging.

Remarks

the primary purpose of this header and fake-configrules.cpp is to define the type specialisations of the QueryHandler<TY>::resolve(solution,query) function(s). Below, there is a really confusing and ugly ping-pong game involving the faked solutions and the mocked defaults manager. This is spaghetti code, written for the reason everyone writes spaghetti code: to get away with it. So please look away, some day the real thing will be there, displacing this mess without further notice.

Todo:

to be removed in Alpha, when integrating a real resolution engine /////////////////TICKET #710
