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

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

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

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

A pattern is a regularity in the world, in human-made design, or in abstract ideas. As such, the elements of a pattern repeat in a predictable manner....

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

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

In software engineering, the composite pattern is a partitioning design pattern. The composite pattern describes a group of objects that are treated the...

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

A dark pattern (also known as a "deceptive design pattern") is a user interface that has been carefully crafted to trick users into doing things, such...

pattern is a design pattern that provides a flexible solution to various object creation problems in object-oriented programming. The builder pattern...

In object-oriented programming, the decorator pattern is a design pattern that allows behavior to be added to an individual object, dynamically, without...

Paisley or paisley pattern is an ornamental textile design using the boteh (Persian: بته) or buta, a teardrop-shaped motif with a curved upper end. Of...

Software architecture pattern is a reusable, proven solution to a specific, recurring problem focused on architectural design challenges, which can be...

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

software design pattern refers to an object that minimizes memory usage by sharing some of its data with other similar objects. The flyweight pattern is one...

Breaker is a design pattern commonly used in software development to improve system resilience and fault tolerance. Circuit breaker pattern can prevent...

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...

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...

single design pattern. Each pattern has a name, a descriptive entry, and some cross-references, much like a dictionary entry. A documented pattern should...

programmer Andrew Koenig, was inspired by the book Design Patterns (which highlights a number of design patterns in software development that its authors considered...

In software engineering, structural design patterns are design patterns that ease the design by identifying a simple way to realize relationships among...

architecture patterns operate at a higher level of abstraction than software design patterns, solving broader system-level challenges. While these patterns typically...

reactor software design pattern is an event handling strategy that can respond to many potential service requests concurrently. The pattern's key component...
