2. Method overriding - Wikipedia

   en.wikipedia.org/wiki/Method_overriding

   Method overriding, in object-oriented programming, is a language feature that allows a subclass or child class to provide a specific implementation of a method that is already provided by one of its superclasses or parent classes. In addition to providing data-driven algorithm-determined parameters across virtual network interfaces, [1] it also ...

3. Polymorphic recursion - Wikipedia

   en.wikipedia.org/wiki/Polymorphic_recursion

   In computer science, polymorphic recursion (also referred to as Milner – Mycroft typability or the Milner–Mycroft calculus) refers to a recursive parametrically polymorphic function where the type parameter changes with each recursive invocation made, instead of staying constant. Type inference for polymorphic recursion is equivalent to ...

4. Inheritance (object-oriented programming) - Wikipedia

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

   Appearance. hide. In object-oriented programming, inheritance is the mechanism of basing an object or class upon another object (prototype-based inheritance) or class (class-based inheritance), retaining similar implementation. Also defined as deriving new classes (sub classes) from existing ones such as super class or base class and then ...

5. Virtual function - Wikipedia

   en.wikipedia.org/wiki/Virtual_function

   In object-oriented programming such as is often used in C++ and Object Pascal, a virtual function or virtual method is an inheritable and overridable function or method that is dispatched dynamically. Virtual functions are an important part of (runtime) polymorphism in object-oriented programming (OOP). They allow for the execution of target ...

6. Object-based language - Wikipedia

   en.wikipedia.org/wiki/Object-based_language

   The term object-based language may be used in a technical sense to describe any programming language that uses the idea of encapsulating state and operations inside objects. Object-based languages need not support inheritance or subtyping, but those that do are also termed object-oriented. Object-based languages that do not support inheritance ...

7. Polymorphism (computer science) - Wikipedia

   en.wikipedia.org/wiki/Polymorphism_(computer...

   Polymorphism can be distinguished by when the implementation is selected: statically (at compile time) or dynamically (at run time, typically via a virtual function). This is known respectively as static dispatch and dynamic dispatch, and the corresponding forms of polymorphism are accordingly called static polymorphism and dynamic polymorphism.

8. Subtyping - Wikipedia

   en.wikipedia.org/wiki/Subtyping

   In programming language theory, subtyping (also called subtype polymorphism or inclusion polymorphism) is a form of type polymorphism.A subtype is a datatype that is related to another datatype (the supertype) by some notion of substitutability, meaning that program elements (typically subroutines or functions), written to operate on elements of the supertype, can also operate on elements of ...

9. Object model - Wikipedia

   en.wikipedia.org/wiki/Object_model

   A collection of objects or classes through which a program can examine and manipulate some specific parts of its world. In other words, the object-oriented interface to some service or system. Such an interface is said to be the object model of the represented service or system. For example, the Document Object Model (DOM) is a collection of ...
