  2. Metaclass - Wikipedia

    en.wikipedia.org/wiki/Metaclass

    Since metaclass objects do not behave differently (you cannot add class methods for a metaclass, so metaclass objects all have the same methods), they are all instances of the same class—the metaclass of the root class (unlike Smalltalk). Thus, the metaclass of the root class is an instance of itself.

  3. Object pool pattern - Wikipedia

    en.wikipedia.org/wiki/Object_pool_pattern

    The object pool pattern is a software creational design pattern that uses a set of initialized objects kept ready to use – a "pool" – rather than allocating and destroying them on demand. A client of the pool will request an object from the pool and perform operations on the returned object.

  4. 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]). Delegation can be termed "run-time ...

  5. Inheritance (object-oriented programming) - Wikipedia

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

    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 is declared as follows:

  6. Class (computer programming) - Wikipedia

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

    In object-oriented programming, a class defines the shared aspects of objects created from the class. The capabilities of a class differ between programming languages, but generally the shared aspects consist of state and behavior that are each either associated with a particular object or with all objects of that class. [1] [2]

  7. 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]

  8. Module pattern - Wikipedia

    en.wikipedia.org/wiki/Module_pattern

    This pattern can be implemented in several ways depending on the host programming language, such as the singleton design pattern, object-oriented static members in a class and procedural global functions. In Python, the pattern is built into the language, and each .py file is automatically a module.

  9. Method overriding - Wikipedia

    en.wikipedia.org/wiki/Method_overriding

    Illustration. 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.
