Lazy Loading in NHibernate

Question

If a Customer has many Orders attached to them. How would you lazy load the Orders List using NHibernate.

Is it something that needs to be set up mapping file? any

Answer 1

Do you want that the Customer entity has a property that contains all his Orders ? I think that this can be quite a large collection.
I think that, the question you'll have to ask yourself is:
How many times do I really need to have direct access to the Orders of a Customer ?

Perhaps, in this case, you don't want to have a bidirectional association ? Perhaps you don't want to have an Orders collection in your Customer class.
Then, I would add a method to my Order Repository, which has the following signature:

IList GetOrdersForCustomer( Customer c );

But, I don't know if this is feasible for your situation.
