  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.

  3. Function overloading - Wikipedia

    en.wikipedia.org/wiki/Function_overloading

    In some programming languages, function overloading or method overloading is the ability to create multiple functions of the same name with different implementations. Calls to an overloaded function will run a specific implementation of that function appropriate to the context of the call, allowing one function call to perform different tasks ...

  4. Operator overloading - Wikipedia

    en.wikipedia.org/wiki/Operator_overloading

    Python allows operator overloading through the implementation of methods with special names. [48] For example, the addition (+) operator can be overloaded by implementing the method obj.__add__(self, other). Ruby allows operator overloading as syntactic sugar for simple method calls.

  5. Method (computer programming) - Wikipedia

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

    Method overloading, on the other hand, refers to differentiating the code used to handle a message based on the parameters of the method. If one views the receiving object as the first parameter in any method then overriding is just a special case of overloading where the selection is based only on the first argument.

  6. Virtual function - Wikipedia

    en.wikipedia.org/wiki/Virtual_function

    Overloading occurs when two or more methods in one class have the same method name but different parameters. Overriding means having two methods with the same method name and parameters. Overloading is also referred to as function matching, and overriding as dynamic function mapping.

  7. Covariance and contravariance (computer science) - Wikipedia

    en.wikipedia.org/wiki/Covariance_and_contra...

    Only a few object-oriented languages actually allow this (for example, Python when typechecked with mypy). C++, Java and most other languages that support overloading and/or shadowing would interpret this as a method with an overloaded or shadowed name. However, Sather supported both covariance and contravariance.

  8. Dynamic dispatch - Wikipedia

    en.wikipedia.org/wiki/Dynamic_dispatch

    In computer science, dynamic dispatch is the process of selecting which implementation of a polymorphic operation (method or function) to call at run time.It is commonly employed in, and considered a prime characteristic of, object-oriented programming (OOP) languages and systems.

  9. Double dispatch - Wikipedia

    en.wikipedia.org/wiki/Double_dispatch

    By contrast, dynamic dispatch is based on the type of the calling object, meaning it uses virtual functions (overriding) instead of function overloading, and does result in a vtable lookup. Consider the following example, written in C++ , of collisions in a game:
