computer programming, the strategy pattern (also known as the policy pattern) is a behavioral software design pattern that enables selecting an algorithm...

In object-oriented programming, the singleton pattern is a software design pattern that restricts the instantiation of a class to a singular instance....

In object-oriented programming, the factory method pattern is a design pattern that uses factory methods to deal with the problem of creating objects...

In software engineering, behavioral design patterns are design patterns that identify common communication patterns among objects. By doing so, these patterns...

In software design and engineering, the observer pattern is a software design pattern in which an object, named the subject, maintains a list of its dependents...

A visitor pattern is a software design pattern that separates the algorithm from the object structure. Because of this separation, new operations can be...

In software engineering, the adapter pattern is a software design pattern (also known as wrapper, an alternative naming shared with the decorator pattern)...

In computer programming, the proxy pattern is a software design pattern. A proxy, in its most general form, is a class functioning as an interface to something...

In software engineering, the mediator pattern defines an object that encapsulates how a set of objects interact. This pattern is considered to be a behavioral...

state pattern is a behavioral software design pattern that allows an object to alter its behavior when its internal state changes. This pattern is close...

In software engineering, creational design patterns are design patterns that deal with object creation mechanisms, trying to create objects in a manner...
