Software patterns

Aka how to code and not reinvent the bloody wheel again

Stolen shamelessly from https://sourcemaking.com/design_patterns

Creational

• Factory = create an object by specifying the type

• Abstract factory = create an object factory by specifying the type

• Builder = build a complex object by separating the construction from the representation (construction is outside the class definition) and construction should be like an assembly.

• Pool = create a pool of objects to reuse, instead of create/destroy cycles

• Singleton = single instance / manager object

• Prototype = create object by copying an existing one

Structural

• Adapter = adapt from 1 interface to another

• Bridge = separate object abstraction(interface) from implementation, and rely on abstraction ( dependency inversion)

• Composite

• Decorator

• Facade

• Flyweight

• Private class data

• Proxy

Behavioural

• Chain of responsibility

• Command

• Interpreter

• Mediator

• Memento

• Null object

• Observer

• State

• Strategy

• Template

• Visitor
