We had a look at our pim implementation and the one from trolltech and we looked what was missing. GOALS: - clean implementation - share code - ObjectOriented Design - Scalable - Integration into common solutions like STL and Qt - Addition - Ease of Use GENERAL: - use templates - have a common base class for all Records OPimRecord - use references instead of pointers - make use of QShared internally memory consumption We've a 'public' and 'private' part in our lib OPimAccessTemplate is the public part. This will be used by 3rd party developers to access the PIMs. OPimAccessBackend is the backend. You could also call it resource. Both things need to be implemented for different kind of records. By using templates we can make sure we share code and the reason not to use simple inheretance is that we can specialise quite easy. For example we have OTodoAccess : public OPimAccessTemplate<OTodo>; the we would do OTodoAccess::List list = otodoAccess.all(); OTodoAccess::List::Iterator it; for( it = list.begin(); it != list.end(); ++it ); as you can see from here it just behaves like you expect from Qt or STL. The kewlest thing is that List and List::Iterator is free to use if you want to implement your own OPimAccessTemplate. You just have to sub class it and voila you're done Hope you enjoy using OPIE PIM -regards Holger 'zecke' Freyther
