Is the code below the only way to impl开发者_运维技巧ement covariant return types? public abstract class BaseApplication<T> {
In my MATLAB program, I have the occurrences of the m-dimensional variable X given in a matrix as X = [x_11 x_12 ... x_1m;
In the code below: interface I1 { } class CI1: I1 { } List<CI1> listOfCI1 = new List<CI1>();
class A{ public: virtual char &operator[](int); protected: .. }; class B:A{ public: A* &operator[](int);
It appears that in C# 4.0, variance specifiers are only applicable to interface types. So let\'s say I have ViewModel / EditModel classes and a simple hierarc开发者_运维技巧hy of models.
