  2. Method overriding - Wikipedia

    en.wikipedia.org/wiki/Method_overriding

    Thought dates = new Advice (); // Polymorphism dates. message (); // Prints "Warning: Dates in calendar are closer than they appear." When a subclass contains a method that overrides a method of the superclass, then that (superclass's) overridden method can be explicitly invoked from within a subclass's method by using the keyword super . [ 3 ] (

  3. 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 ...

  4. Row polymorphism - Wikipedia

    en.wikipedia.org/wiki/Row_polymorphism

    In programming language type theory, row polymorphism is a kind of polymorphism that allows one to write programs that are polymorphic on row types such as record types and polymorphic variants. [1] A row-polymorphic type system and proof of type inference was introduced by Mitchell Wand .

  5. Duck typing - Wikipedia

    en.wikipedia.org/wiki/Duck_typing

    Duck typing is similar to, but distinct from, structural typing.Structural typing is a static typing system that determines type compatibility and equivalence by a type's structure, whereas duck typing is dynamic and determines type compatibility by only that part of a type's structure that is accessed during runtime.

  6. Polymorphism (computer science) - Wikipedia

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

    Ad hoc polymorphism was a feature of ALGOL 68, while parametric polymorphism was the core feature of ML's type system. In a 1985 paper, Peter Wegner and Luca Cardelli introduced the term inclusion polymorphism to model subtypes and inheritance, [1] citing Simula as the first programming language to implement it.

  7. Dynamic dispatch - Wikipedia

    en.wikipedia.org/wiki/Dynamic_dispatch

    The choices of the dynamic dispatch mechanism offered by a language to a large extent alter the programming paradigms that are available or are most natural to use within a given language. Normally, in a typed language, the dispatch mechanism will be performed based on the type of the arguments (most commonly based on the type of the receiver ...

  8. Operator overloading - Wikipedia

    en.wikipedia.org/wiki/Operator_overloading

    In computer programming, operator overloading, sometimes termed operator ad hoc polymorphism, is a specific case of polymorphism, where different operators have different implementations depending on their arguments. Operator overloading is generally defined by a programming language, a programmer, or both.

  9. Python (programming language) - Wikipedia

    en.wikipedia.org/wiki/Python_(programming_language)

    Go is designed for the "speed of working in a dynamic language like Python" [238] and shares the same syntax for slicing arrays. Groovy was motivated by the desire to bring the Python design philosophy to Java. [239] Julia was designed to be "as usable for general programming as Python". [27]
