Given the following code class T { pu开发者_JS百科blic: virtual ~T () {} virtual void foo () = 0; }; class U {
In C++, my understanding is that virtual function can be inlined, but generally, the hint to inline is ignored.It seems that inline virtu开发者_如何学Pythonal functions do not make too much sense.
I wanted to know how fast is a single-inheritance virtual function call when compared to one same boost::function call. Are they almost the same in performance or is boost::function slower?
Consider this simple situation: A.h class A { public: virtual void a() = 0; }; B.h #include <iostream>
I have a class which doesn\'t currently need to be thread-safe, b开发者_Python百科ut in future we might want to make a thread-safe version.The way I see it, I can either make it thread-safe now by put
I have something similar to this in my code: #include <iostream> #include <cstdlib> struct Base
I have some questions about the object size with virtual. 1) virtual function class A { public: int a; virtual void v();
When implementing polymorphic behavior in C++ one can either use a pure virtual method or one can use function pointers (or functors). For example an asynchronous callback can be implemented by:
In the C++ program: #include<iostream.h> class A { public: virtual void func()=0; }; class B:public A
In my C++ program: #include<iostream.h> class A { public: virtual void func() { cout<<\"In A\"<<endl;
