In one of my previous article about Factory Pattern I spoke about what are different flavors of Factory pattern and how to choose between them. Each of the factory methods creates a different kind of object. ConcreteFactory implementations implement the abstract create methods to produce ConcreteProducts. Pros.

Abstract Factory patterns work around a super-factory which creates other factories. Die abstrakte Fabrik kann daher eine ganze Produktfamilie austauschbar machen, während sich die Fabrikmethode … First of all both of them falls under Creational category and it means it will solves the problem pertaining to object creation. The abstract factory doesn't build anything. With the Factory method, we not only abstract product creation, but take one step further. Builder, on the other hand, is concerned with building a single type of object. Abstract Factory classes are often based on a set of Factory Methods, but you can also use Prototype to compose the methods on these classes.

What are MVP and MVC and what is the difference? Abstract Factory is a creational design pattern, which solves the problem of creating entire product families without specifying their concrete classes. Design patterns are reusable and documented solutions for commonly occurring problems in software programming or development. What is the difference between Builder Design pattern and Factory Design pattern? Do you need a valid visa to move out of the country? Factory Method defines an interface for creating an object, but lets subclasses decide which of those to instantiate. Is that explanation of Factory method correct? There will be an intermediary class which will have composition relationship with our interface. The interface of an Abstract Factory will typically contain a number of Factory Methods, one for each type of object to be created.

The abstract factory pattern provides a way to encapsulate a group of individual factories that have a common theme without specifying their concrete classes. Der Begriff Fabrikmethode (englisch factory method) bezeichnet ein Entwurfsmuster aus dem Bereich der Softwareentwicklung.Das Muster beschreibt, wie ein Objekt durch Aufruf einer Methode anstatt durch direkten Aufruf eines Konstruktors erzeugt wird. (Instruction through Inheritance) But the book also says Abstract Factory is often implemented with factory methods. The purpose of a Class having factory method is not just create objects, it does other work also, only a method is responsible for creating object. My presentation on what is factory method and abstract factory for software architecture and design pattern, =) So the concrete factory class, and the resulting manufactured object, will depend on what implementations have been made available or the getInstance() might take some parameters which chose from a selection of potential implementations. The Abstract Factory pattern is about creating a class that has A favourite technique is … it will better to answer the question rather than down voting it :), there are so many good answers on those other questions, many of which offer guidance as to when to follow each, Factory vs Abstract Factory Design Pattern, Podcast 294: Cleaning up build systems and gathering computer history.

Factory Pattern A client uses a Factory Class to get instances of classes that implement the same interface or are derived from the same base class. Your specifications are inputs for the factory, and the door is the output or product from the factory. * How is the Abstract Factory different from the Factory Method pattern? Implementation. Let see what will be the best design for that, I think now you know what is the difference between Factory Method Pattern and Abstract Factory. By contrast, an Abstract Factory provides an interface for creating families of related or dependent objects without specifying their concrete classes. The Factory method lets a class defer instantiation to subclasses". Each factory type corresponds to a certain product variety. The idea is that at the point of creation of the factory object, you decide how all the objects created by that factory will be used. In simple words, interface will expose multiple methods each of which will create some object. It looks strange when you use following names: Thank you very much for your nice articale.

How to if there are same method only parameters different. All this objects will together become the part of some important functionality. In my previous article, we covered Factory Method Design Pattern In C#. In normal usage, the client software creates a concrete implementation of the abstract factory and then uses the generic interface of the factory to create the concrete objects that are part of the theme. In Abstract Factory pattern an interface is responsible for creating a factory of related objects without explicitly specifying their classes. Keep it up once again. Calculating Parking Fees Among Two Dates . The classical GoF Abstract Factory design pattern is modified inthe following two ways: A factory interface replaces the abstract factory class (Optional), Every factory method is responsible for creating an object and injecting its dependencies. Typically an abstract factory has a static getInstance() method which searches for a concrete implementation of the factory. Abstract Factory can be used as an alternative to Facade to hide platform-specific classes. Abstract factory pattern implementation provides us a framework that allows us to create objects that follow a general pattern. Video series on Design Patterns for Object Oriented Languages. Please add comment when you down vote :) , I didn't see is there any thing wrong in the question? Let’s talk about a scenario.

Each generated factory can give the objects as per the Factory pattern. An Abstract Factory, much like a Strategy, is often selected using a Factory Method, but it isn't necessary to combine them so it is its own pattern. Best C# Article of January 2014 : First Prize.
