Abstract Factory
But Factory Method is implemented by Inheritance. The generated factory from an abstract factory pattern always generates the object as per the factory design pattern.

Abstract Factory is a creational design pattern which solves the problem of creating entire product families without specifying their concrete classes.
Abstract factory. The Abstract Factory interface declares a set of methods for creating each of the abstract products. Factory Patterns includes a factory which is responsible for creating one or more type of objects where as Abstract Factory creates a family of different types of objects. In this article I am going to discuss the Abstract Factory Design Pattern in C with an example.
The main difference between Abstract Factory and Factory Method is that Abstract Factory is implemented by Composition. Abstract Factory Design Pattern in C with Real-Time Example. Abstract factory pattern provides a framework that allows to create objects that follows a pattern.
UML diagrams can be found in the GoF book. Abstract factory pattern implementation provides us with a framework that allows us to create objects that follow a general pattern. Please read our previous article where we discussed the Factory Method Design Pattern in C with an example.
The Abstract Factory Design Pattern belongs to the creational design pattern category and is one of the most used design. The abstract factory works as a factory of factories which generates other factories by providing an extra abstraction layer. UML class diagram A visualization of the classes and objects participating in this pattern.
So at runtime the abstract factory is coupled with any desired concrete factory which can create objects of the desired type. Abstract Products declare interfaces for a set of distinct but related products which make up a product family. Abstract Factory pattern is almost similar to Factory Pattern and is considered to have a extra layer of abstraction over factory pattern.
Instead of needing to create a hard source code dependency by importing the type of Pokemon that we want like. The abstract factory will define types of toppings for pizza like pepperoni sausage or anchovy and the concrete factories will implement only a set of the toppings which are specific for the area and even if one topping is implemented in both concrete factories the resulting pizzas will be different subclasses each for the area it was. Abstract Factory design pattern is a part of Creational pattern.
So at runtime the abstract factory is coupled with any desired concrete factory that can create objects of the desired type. Abstract factory pattern is yet another creational design pattern and is considered as another layer of abstraction over factory patternIn this tutorial we will expand the scope of car factory problem discussed in factory patternWe will learn when to use factory pattern by expanding scope of car factory and then how abstract factory pattern solves the expanded scope. In other words We can also say that the abstract factory is a factory of related objects.
Abstract Factory Design Pattern Benefits. Concrete Products are various implementations of abstract products grouped by variants. The Abstract Factory design pattern provides an interface for creating families of related or dependent objects without specifying their concrete classes.
Abstract Factory defines an interface for creating all distinct products but leaves the actual product creation to concrete factory classes. That definition probably makes a little bit more sense now given the context. The main difference between these two patterns is the old composition vs inheritance debate.
Each abstract product chairsofa must be implemented in all given variants VictorianModern. C Patterns Intro. Abstract Factory patterns work around a super-factory which creates other factories.
Abstract Factory pattern is factory of factories and can be easily extended to accommodate more products for example we can add another sub-class Laptop and a factory LaptopFactory. Abstract Factory design pattern provides approach to code for interface rather than implementation. Abstract Factory Design Pattern is a super-factory that creates other factories.
Yes you read that correctly. So at runtime abstract factory is coupled. Abstract Factory Design Pattern implementation provides us a framework that allows us to create objects that follow a general pattern.
The abstract factory pattern provides a way to encapsulate a group of individual factories that have a common theme without specifying their concrete classes.
