Hibernate can do bidirectional polymorphism with TABLE_PER_CLASS (<union-subclass>), says so here:
I\'m using shoulda-matchers with rails and I\'m creating a model called \"comments\" and another model called \"post\". Comments is polymorphic.
public class A {} public class B : A {} now what the best way to get this working List<A> a; List<B> b = new List<B>();
I have a polymorphic model called Address, I am trying to currently write some basic function tests for this model and controller. For the controller I am at a loss on how to go about this. For exampl
My class A is dependent to class B. Here is the code //declaration class A { public: A(B *b); ~A(); void m1();
This is not a question about how they work and declared, this I think is pretty much clear to me. The question is about why to implement this?
Is it possible with .NET standard JavascriptSerializer/JsonDataContractSerializer or external parsers, to serialize objects array using a wrapper approach including the object type?
what I am using: VB.NET, NET 3.5, OpenXML SDK 2.0 what I want to do: I am creating an xlsx reader / writer for my application (based on OpenXML SDK 2.0). I want to read xlsx files and store the data
I have the following set up: public abstract class A { public void f() { //Want to make an instance of B or C here
Unlike the asmx implementation the wcf requires for you to implement it\'s interface. I do not quite understand the reason behind that design. Interface is a contract between 2 classes...With that bei
