⁠Design patterns module

⁠Creational

Factory "Define an interface for creating an object, but let subclasses decide which class to instantiate. Factory Method lets a class defer instantiation to sub-classes." (GOF)

Abstract Factory "Provide an interface for creating families of related or dependent objects without specifying their concrete classes." (GOF)

Builder "Separate the construction of a complex object from its representation so that the same construction process can create different representations." (GOF)

Prototype "Specify the kinds of objects to create using a prototypical instance, and create new objects by copying this prototype." (GOF)

Singleton "Ensure a class only has one instance, and provide a global point of access to it." (GOF)

⁠Structural

Adapter "Convert the interface of a class into another interface clients expect. Adapter lets classes work together that couldn't otherwise because of incompatible interfaces." (GOF)

Bridge"Decouple an abstraction from its implementation so that the two can vary independently." (GOF)

Composite"Compose objects into tree structures to represent part-whole hierarchies. Composite lets clients treat individual objects and compositions of objects uniformly." (GOF)

Decorator "Attach additional responsibilities to an object dynamically. Decorators provide a flexible alternative to subclassing for extending functionality." (GOF)
