  2. Multiple inheritance - Wikipedia

    en.wikipedia.org/wiki/Multiple_inheritance

    Multiple inheritance is a feature of some object-oriented computer programming languages in which an object or class can inherit features from more than one parent object or parent class. It is distinct from single inheritance, where an object or class may only inherit from one particular object or class.

  3. Inheritance (object-oriented programming) - Wikipedia

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

    Multilevel inheritance The class A serves as a base class for the derived class B, which in turn serves as a base class for the derived class C. The class B is known as intermediate base class because it provides a link for the inheritance between A and C. The chain ABC is known as inheritance path. A derived class with multilevel inheritance ...

  4. Composition over inheritance - Wikipedia

    en.wikipedia.org/wiki/Composition_over_inheritance

    Composition over inheritance (or composite reuse principle) in object-oriented programming (OOP) is the principle that classes should favor polymorphic behavior and code reuse by their composition (by containing instances of other classes that implement the desired functionality) over inheritance from a base or parent class. [2]

  5. Object-oriented programming - Wikipedia

    en.wikipedia.org/wiki/Object-oriented_programming

    Object-oriented programming (OOP) is a programming paradigm based on the concept of objects, [1] which can contain data and code: data in the form of fields (often known as attributes or properties), and code in the form of procedures (often known as methods).

  6. 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. [1]

  7. C3 linearization - Wikipedia

    en.wikipedia.org/wiki/C3_linearization

    C3 superclass linearization is an algorithm used primarily to obtain the order in which methods should be inherited in the presence of multiple inheritance.In other words, the output of C3 superclass linearization is a deterministic Method Resolution Order (MRO).

  8. Delegation (object-oriented programming) - Wikipedia

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

    Inheritance, by contrast, typically targets the type rather than the instances, and is restricted to compile time. On the other hand, inheritance can be statically type-checked, while delegation generally cannot without generics (although a restricted version of delegation can be statically typesafe [ 7 ] ).

  9. Singly rooted hierarchy - Wikipedia

    en.wikipedia.org/wiki/Singly_rooted_hierarchy

    The singly rooted hierarchy, in object-oriented programming, is a characteristic of most (but not all) OOP-based programming languages.In most such languages, in fact, all classes inherit directly or indirectly from a single root, usually with a name similar to Object; all classes then form a common inheritance hierarchy.
