All factory design patterns help you create objects without using the new keyword directly within your code. The difference between this and the abstract factory pattern is that the static factory pattern uses just one static method to create all types of objects it … This structural code demonstrates the Abstract Factory pattern creating parallel hierarchies of objects. But I think there are some confusion with regards to Factory Method Pattern and Abstract Factory. All factory design patterns help you create objects without using the new keyword directly within your code. These type of methods share the same benefits as the traditional factory method design pattern. First of all we have some interfaces and implementation for the objects in the kingdom. In my previous article, we covered Factory Method Design Pattern In C#. So basically, an Abstract Factory class has a collection of different Factory Methods to create different desired Concrete objects. While implementing Abstract factory pattern, the factory classes can have multiple factory methods. Instead, a car factory will create a specific type of car with the common properties and behaviors of a car. In this article, we'll discuss the Abstract Factory design pattern.The book Design Patterns: Elements of Reusable Object-Oriented Software states that an Abstract Factory “provides an interface for creating families of related or dependent objects without specifying their concrete classes”. In this article, I will try to highlight the usage of the pattern along with the difference with the Factory Pattern. This website is not affiliated with Oracle™ and/or any of the JEE frameworks like Spring™, Struts™, Hibernate™ and JSF™. Abstract Factory. Factory method pattern create an abstraction to create objects and defer instantiation to subclasses thus allowing subclasses to decide which class to instantiate. Abstract factory can be considered as a factory of factories. Abstract Factories¶ The Abstract Factory pattern looks like the factory objects we’ve seen previously, with not one but several factory methods. Third Pattern: The Static Factory Method. Programmatic Example. Non-Static Factory implementing FactoryMethod example is available in this post: Design Patterns: Factory vs Factory method vs Abstract Factory. In the Shape example, instead of having a separate Shape Factory, we can create a new abstract method getShape() within the client class (also making the client class as abstract) and then call it as below. Even if you have an interface reference type pointing to a concrete instantiation using “new”, you will still need to change your code to change the concrete class, which is against the ‘closed for modification’ part of the Open Close Principle. Factory Method lets a class defer instantiation to subclasses. Garment Factory produce different kinds of clothes, On the other hand, Abstract Factory … This factory is then used to obtain an implementation of IDinosaur. The phrase "Factory Pattern" is rather overloaded so I'm going to give you a quick crash course in the three main types of factories. Implementing CRM System With Laravel Part 12: Calendar Module, Building a Blog With Reactjs And Laravel Part3: Begin Reactjs, Building A Simple Scraping Website With PHP Laravel Part3: Article Display, © 2020 Web and Mobile Tutorials. For this reason the simple pattern is usually preferred over the static pattern. Please read our previous article where we discussed the Factory Method Design Pattern in C# with an example. The abstract factory ShapeFactory will return a WindowsShapeFactory or LinuxShapeFactory based on the operating system and then you can ask this returned factory for a Shape object the same way as you did with the ShapeFactory before. In this pattern instead of having one static factory method, you have a factory method for each class you want to initialize. By using this site in any way, you agree to the terms of use and also confirm that you have read our copyright and trademark notice. /* 160x600 Text Image */ This is especially useful for value objects that don’t have a separate interface and implementation class. Clients manipulate instances through their abstract interfaces. Actually, they do not ca… Factory method pattern makes use of the inheritance feature of Object Oriented Programming languages to attain code reuse and gives a lot of flexibility, and also avoids the need for a separate class for instance creation. Using an abstract factory, we can make a DinosaurNoiseProducer class, which looks like this: Its constructor takes in an IDinosaurFactory. Abstract Factory Design Pattern in C# with Real-Time Example. Factory Design Pattern Class diagram for the example: Figure 1: Factory Pattern Class diagram "MyFactory" is the static class that has the responsibility of creating an actual instance of the concrete class and sends the reference to the client class. Abstract Factory is also factory pattern, the only difference being that in Abstract Factory clients code against a Interface/Abstract class instead of a concreate instance of factory.
