2. Virtual function - Wikipedia

   en.wikipedia.org/wiki/Virtual_function

   Virtual functions allow a program to call methods that don't necessarily even exist at the moment the code is compiled. [citation needed] In C++, virtual methods are declared by prepending the virtual keyword to the function's declaration in the base class. This modifier is inherited by all implementations of that method in derived classes ...

3. Virtual method table - Wikipedia

   en.wikipedia.org/wiki/Virtual_method_table

   An object's virtual method table will contain the addresses of the object's dynamically bound methods. Method calls are performed by fetching the method's address from the object's virtual method table. The virtual method table is the same for all objects belonging to the same class, and is therefore typically shared between them.

4. Inheritance (object-oriented programming) - Wikipedia

   en.wikipedia.org/wiki/Inheritance_(object...

   Some languages require that method be specifically declared as virtual (e.g. C++), and in others, all methods are virtual (e.g. Java). An invocation of a non-virtual method will always be statically dispatched (i.e. the address of the function call is determined at compile-time).

6. Dynamic dispatch - Wikipedia

   en.wikipedia.org/wiki/Dynamic_dispatch

   The default form of dispatch is static. To get dynamic dispatch the programmer must declare a method as virtual. C++ compilers typically implement dynamic dispatch with a data structure called a virtual function table (vtable) that defines the name-to-implementation mapping for a given class as a set of member function pointers. This is purely ...

7. Class (computer programming) - Wikipedia

   en.wikipedia.org/wiki/Class_(computer_programming)

   [26] [27] In C++, an abstract class is a class having at least one abstract method given by the appropriate syntax in that language (a pure virtual function in C++ parlance). [25] A class consisting of only pure virtual methods is called a pure abstract base class (or pure ABC) in C++ and is also known as an interface by users of the language. [13]

8. Double dispatch - Wikipedia

   en.wikipedia.org/wiki/Double_dispatch

   In most object-oriented systems, the concrete function that is called from a function call in the code depends on the dynamic type of a single object and therefore they are known as single dispatch calls, or simply virtual function calls. Dan Ingalls first described how to use double dispatching in Smalltalk, calling it multiple polymorphism. [1]

9. Method (computer programming) - Wikipedia

   en.wikipedia.org/wiki/Method_(computer_programming)

   A method in object-oriented programming (OOP) is a procedure associated with an object, and generally also a message. An object consists of state data and behavior; these compose an interface, which specifies how the object may be used. A method is a behavior of an object parametrized by a user.
