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; -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 - - - - - - -- cgit v0.9.0.2
