Thanks guys, I took a look at the linq-specifications code base on google
but it's not quite what I'm looking for.
What I want is to create concrete classes that are my specifications. In a
billing system some examples may be:
LateChargesSpecification
ActiveCustomerSpecification
GoodCustomerDiscountSpecification
And I'd like these to be passed into an Account repository with a signature
like this:
public class MyRepo
{
public IList<Account> SpecifiedBy(IList<ISpecification> specifications)
}
And a usage example could be:
var mySpecifications = new
IList<ISpecification>{ ActiveCustomerSpecification,
GoodCustomerDiscountSpecification
};
var activeCustomersWithDiscount = acctRepo.SpecifiedBy( mySpecifications );
I don't want any NHibernate specific dialect sprinkled at this level, but I
completely understand how my specifications will contain criteria or linq
predicates.
So guys, this is what I'm looking for, but I have no idea how to implement
it. Again thanks for your help and I appreciate all your guidance.
Thanks,
Sam
