The idea of this suggestion is to minify the ISpecification interface to:
public interface ISpecification<T> { Expression<Func<T, bool>> ToExpression(); }
and have IsSatisfiedBy
as extension method instead of base abstract implementation. Benefits I see in this approach is following:
IsSatisifedBy
is granted to have exactly same behaviour as underlying expression. Now a class implementing interface can have two completely different implementation for this methods.IsSatisfiedBy
when the class to which we pass mocked ISpecification
actually uses ToExpression
.Thanks for your contributions. I look forward to contributing to this effort.
You mentioned this "just works" with the MonogDb driver, but also that the next step was to determine what works and what doesn't with the MongoDb driver.
Can you kindly give an example of such usage? I'm assuming you just pass the specification.ToExpression() to a find?
