  2. Inheritance (object-oriented programming) - Wikipedia

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

    Implementation inheritance is controversial among programmers and theoreticians of object-oriented programming since at least the 1990s. Among them are the authors of Design Patterns, who advocate interface inheritance instead, and favor composition over inheritance

  3. Composition over inheritance - Wikipedia

    en.wikipedia.org/wiki/Composition_over_inheritance

    Ideally all reuse can be achieved by assembling existing components, but in practice inheritance is often needed to make new ones. Therefore inheritance and object composition typically work hand-in-hand, as discussed in the book Design Patterns (1994). [3]

  4. Design Patterns - Wikipedia

    en.wikipedia.org/wiki/Design_Patterns

    Design Patterns: Elements of Reusable Object-Oriented Software (1994) is a software engineering book describing software design patterns. The book was written by Erich Gamma , Richard Helm , Ralph Johnson , and John Vlissides , with a foreword by Grady Booch .

  5. Object-oriented programming - Wikipedia

    en.wikipedia.org/wiki/Object-oriented_programming

    Design Patterns: Elements of Reusable Object-Oriented Software is an influential book published in 1994 by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides, often referred to humorously as the "Gang of Four". Along with exploring the capabilities and pitfalls of object-oriented programming, it describes 23 common programming ...

  6. Bridge pattern - Wikipedia

    en.wikipedia.org/wiki/Bridge_pattern

    The bridge pattern is a design pattern used in software engineering that is meant to "decouple an abstraction from its implementation so that the two can vary independently", introduced by the Gang of Four. [1] The bridge uses encapsulation, aggregation, and can use inheritance to separate responsibilities into different classes.

  7. Twin pattern - Wikipedia

    en.wikipedia.org/wiki/Twin_pattern

    In software engineering, the Twin pattern is a software design pattern that allows developers to model multiple inheritance in programming languages that do not support multiple inheritance. This pattern avoids many of the problems with multiple inheritance.

  8. Entity component system - Wikipedia

    en.wikipedia.org/wiki/Entity_component_system

    Entity–component–system (ECS) is a software architectural pattern mostly used in video game development for the representation of game world objects. An ECS comprises entities composed from components of data, with systems which operate on the components.

  9. Abstract factory pattern - Wikipedia

    en.wikipedia.org/wiki/Abstract_factory_pattern

    The original structure of the abstract factory pattern, as defined in 1994 in Design Patterns, is based on abstract classes for the abstract factory and the abstract products to be created. The concrete factories and products are classes that specialize the abstract classes using inheritance. [4]
