Please suppose I have the following extension method in order to be able to force evaluation of an IEnumerable:
Consider the following code: struct Base {}; struct Derived : public virtual Base {}; void f() { Base* b = new Derived;
I have a project where I\'ve defined in EF an Employer as a derived class of User.In my process I create a user without knowing whether it will eventually be an employer (or other kinds of users) and
This is somewhat hypothetical as I\'m not too worried about performance - just wondering which option is actually the fastest/most efficient in general, or if there is no difference whatsoever.
A tweak on this question that I\'ve run into. Consider: class A {}; class B : private A { static void foo();
Consider: struct SomethingThatsABase { virtual bool IsChildOne() const { return false; } virtual bool IsChildTwo() const { return false; }
Run time exception-- java.lang.ClassCastingException... Integer intArr[] = new Integer[arrList.size()];
Coming from a non-Java background to Scala has brought me a wide range of difficulties including this one.
I\'m trying to see if HashSet would be the solution for my next project so i\'m doing some very easy test to check functionalities.
