I\'m using virtual inheritance as in the typical diamond problem: A (virtual) /\\ (virtual) BC \\/ D I\'m implementing a method named \"deep_copy_from\" in every class (but it could be the assignme
I was working the last 5 years with the assumption that virtual inheri开发者_开发问答tance breaks static composition.
I have the code below: class A { }; class B: public virtual A { public: B() { cerr << \"B()\"; } 开发者_开发技巧B(const A& a)
I have four classes: class A {}; class B : virtual public A {}; class C : vi开发者_如何学JAVArtual public A {};
Is there a (practical) way to by-pass the normal (virtual) constructor calling order? Example: class A {
I have never seen a class used as virtual and nonvirtual base (i.e. if some class is intended to be an ancestor then we usually know in advance about type of inheritance - virtual or nonvirtual).
I understand the basics of C++ virtual inheritance.However, I\'m confused about where exactly I need to use the virtual keyword with a complex class hierarchy.For example, suppose I have the following
I am little confused about vptr and representation of objects in the memory, and hope you can help me understand the matter better.
Consider the following class hierarchy: base class Object with a virtual method foo() an arbitrary hierarchy with multiple inheritance (virtual and non-virtual); each class is a subtype of Object; s
I am trying to refactor some code while leaving existing functionality in tact. I\'m having trouble casting a pointer to an object into a base interface and then getting the derived class out later. T
