> this proposal is for creating a loading context into hibernate
>  Let me explain:
>  On an application, we often hesitating between the two major strategies of loading (eager or lazy). But for some reason there has no good choice. In fact, it depends on the context. 
> So we do lazy loading and redefine some method with new request with some "join". In fact, it lead to complexity and decrease managability of the application.
> So my idea is to allow the definition of a context (like transactional context) where we we can put the loading strategie to adopt. 
> with annotation it could be very easy to define such context. Let see this exemple :
> Avec les annotations, cela pourrait conduire à une ecriture de ce style :
> @LoadingStrategie (type=eager from="Car" get={"driver"})
> public List<Car> getAllCarForDriving(){
> // Some fonctions
> }
> @LoadingStrategie (type=eager from="Car" get={"driver","passengers"})
> public List<Car> getAllCarForTravelling(){
> // Some fonctions
> }
> In the method getAllCarForDriving when we call a hql request on car it automaticaly get driver but in the method getAllCarForTravelling passengers and the driver is loaded.
