  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. Matching pursuit - Wikipedia

    en.wikipedia.org/wiki/Matching_pursuit

    Matching pursuit has been applied to signal, image [2] and video coding, [3] [4] shape representation and recognition, [5] 3D objects coding, [6] and in interdisciplinary applications like structural health monitoring. [7] It has been shown that it performs better than DCT based coding for low bit rates in both efficiency of coding and quality ...

    en.wikipedia.org/wiki/Curiously_recurring...

    In the above example, the function Base<Derived>::interface(), though declared before the existence of the struct Derived is known by the compiler (i.e., before Derived is declared), is not actually instantiated by the compiler until it is actually called by some later code which occurs after the declaration of Derived (not shown in the above ...

  5. C3 linearization - Wikipedia

    en.wikipedia.org/wiki/C3_linearization

    Python's Guido van Rossum summarizes C3 superclass linearization thus: [11] Basically, the idea behind C3 is that if you write down all of the ordering rules imposed by inheritance relationships in a complex class hierarchy, the algorithm will determine a monotonic ordering of the classes that satisfies all of them.

  6. Class hierarchy - Wikipedia

    en.wikipedia.org/wiki/Class_hierarchy

    In general, the further down in the hierarchy a class appears, the more specialized its behavior. When a message is sent to an object, it is passed up the inheritance tree starting from the class of the receiving object until a definition is found for the method. This process is called upcasting.

  7. Inheritance (object-oriented programming) - Wikipedia

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

    When inheritance was used as a primary approach to structure programs in the late 1990s, developers tended to break code into more layers of inheritance as the system functionality grew. If a development team combined multiple layers of inheritance with the single responsibility principle, this resulted in many very thin layers of code, with ...

  8. is-a - Wikipedia

    en.wikipedia.org/wiki/Is-a

    The following python code establishes an explicit inheritance relationship between classes B and A, where B is both a subclass and a subtype of A, and can be used as an A wherever a B is required. class A : def do_something_a_like ( self ): pass class B ( A ): def do_something_b_like ( self ): pass def use_an_a ( some_a ): some_a . do_something ...

  9. 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.
