[Note: the interpretation of the call of a virtual function depends on the type of the object for which it is called (the dynamic type), whereas the interpretation of a call of a nonvirtual member function depends only on the type of the pointer or reference denoting that object (the stat...
As you point out, things are different in C#. Managed objects—whether in C#, managed C++, or any other .NET-compliant language—are created as their final type, which means that if you call a virtual function from a constructor or destructor, the system calls the most...
Only that's not really true. Let's take item (1) first: there are many cases in which a virtual function is resolved statically — essentially any time a derived class virtual method invokes the method of its base class(es). Why would one do that? Encapsulation. A good example is the...
But while it's logical, this behavior can cause bugs. As a general rule, you should never call a virtual function from a constructor or destructor unless you intend the call to be non-virtual. A similar thing happens with the vtables during destruction. Before your destruction code executes...
I have presented the elements of vtables by gdb, which may be another way. #include <iostream> // the virtual table class Base { public: virtual void function1() { std::cout << "Base::function1\n"; } virtual void function2() { std::cout << "Base::function2\n"; } }; class...
CFoo:: GetVal, it will instantiate it as a static function in mumble.cpp. If 10 modules include foo.h, the compiler could generate up to 10 copies of your virtual function. In fact, you could end up with objects of the same type with vtables pointing to different copies of GetVal. ...

When any of the options under Data Collection in the Security & Privacy screen of the appliance UI is enabled, Cisco reserves the right to collect more data for diagnosis and proactive troubleshooting purposes. The tables below list the details of the minimum data coll...
Instead, the table definitions can be retrieved from a P_S function as SQL DDL statements, which can then be executed by the DD initialization code. A mechanism similar to what the server and the DDSE uses for allowing the server to create tables on behalf the DDSE, may be used. The ...
