Consider the following simple program which is an example of runtime polymorphism. The main thing to note about the program is, derived class function is A virtual method table (VMT), virtual function table, virtual call table, dispatch table, vtable, or vftable is a mechanism used in a Mar 14, 2009 Virtual Table is a lookup table of function pointers used to dynamically bind the virtual Here is a simple example with a vtable representation.Jun 10, 2017 For every class that contains virtual functions, the compiler constructs a virtual table, a.k.a vtable. The vtable contains an entry for each virtual function accessible by the class and stores a pointer to its definition. Only the most specific function definition callable by the class is stored in the vtable. Sep 13, 2015 The object of the class containing the virtual function contains a virtual pointer .. So for example, if most of your objects refer to the same implementation of a Feb 8, 2008 First, every class that uses virtual functions (or is derived from a class that uses virtual functions) is given its own virtual table. This table is simply a static array that the compiler sets up at compile time. A virtual table contains one entry for each virtual function that can be called by objects of the class. Mar 1, 2016 Because there's a hidden pointer inside it pointing to a vtable . vtable s are static translation tables, created for each virtual-class. This post Feb 19, 2015 What is vtable & vPointer and How C++ do run time binding using them: vTable: . Click Here to Subscribe for more Articles / Tutorials like this. As the class contains a virtual function C++ compiler inserts a pointer v_ptr called as virtual table pointer. Compiler also creates a table for that class called as virtual table known as vtable for the class. The table is created compile time v_ptr holds the address of v_table of the corresponding class. So, the specific behaviors of a derived class object are sliced off. We're left with a base class object. In other words, if we upcast (Upcasting and Down Casting)
