Purpose: Illustrate Abstract Factory design pattern.. Summary: Abstract Factory is creational software design pattern.This pattern provides interfaces for creating families of related or dependent objects without specifying their concrete classes. Abstract Factory Design Pattern in C# with Real-Time Example. The Abstract Factory pattern has both benefits and flaws. According to the Gang of Four, the intent of the Abstract Factory Method is to: “Provide an interface for creating families of related or dependent objects without specifying their concrete classes.” An Abstract Factory is a class with several Factory methods. From using this pattern, you don't need to know at design time what the actual Factory object is as long as it implements this interface. I'm reading this book "Design Patterms Elements of Reusable Object-Oriented Software" and it's got exactly what you want in it. the necessary/required signatures. Abstract Factory Design Pattern. By now, you should be able to count the main advantages of using the factory pattern. This factory is also called as factory of factories. The Abstract Factory pattern has the following benefits and liabilities: I can't say I've ever used it, but the book has excellent content, UML diagrams and is well worth the read. This structural code demonstrates the Abstract Factory pattern creating parallel hierarchies of objects. So, Microsoft Sql Server has a factory This type of design pattern comes under creational pattern as this pattern provides one of the best ways to create an object. As we previously noted, the abstract factory pattern allows us to easily re-use components as abstract classes and enforce specific concrete subclasses to be used as part of a component family. } Overview. In contrast, abstract factory pattern provides a method to combine a group of individual factories without specifying their concrete classes. 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. The main difference between factory and facade design pattern is that the factory design pattern is a creational design pattern that defines an interface or an abstract class to create an object, while the facade design pattern is a structural design pattern that provides a simplified interface to represent a set of interfaces in a subsystem to hide its complexity from the client. To help, the Factory is a pattern used to describe encapsulating the creation of objects. Abstract factory adds another level of abstraction to factory method. public abstract CarFactory The Abstract Factory pattern has the following benefits and liabilities: It isolates concrete classes. If you don't use the Factory pattern now, this makes it a little harder to understand. This Factory allows you to create DBConnections, DBDataAdapters, DBCommands, etc, etc. Is there anyone, who can explain to me (in dummy language) what to benefits are of the "Abstract Factory" design pattern and how they work? The first example of this pattern that comes to mind in the .NET Framework is the DBProviderFactory...one of my absolute favorites. On one hand it isolates the creation of objects from the client that needs them, giving the client only the possibility of accessing them through an interface, which makes the manipulation easier. In fact, interfaces are often viewed from the wrong perspective: you can never force client code to use your interface. Given a set of related abstract classes, the Abstract Factory pattern provides a way to create instances of those abstract classes from a matched set of concerte subclases. The family of related product objects is designed to be used together, and you must enforce this constraint. for connecting to Sql, Excel, or Access!! The creation of an object precludes its reuse without significant duplication of code. In America, Honda makes Accord cars and Pilot SUVs while Toyota makes. Abstract Factory returns the product immediately, whereas Builder lets you run some additional construction steps before fetching the product. So at runtime, abstract factory is coupled with any desired concrete factory which can create objects of desired type. The client does not know (or care) which concrete objects it gets from each of these internal factories, since it uses only the generic interfaces of their products.      public override Car CreateCar() Abstract Factory specializes in creating families of related objects. Abstract Factory patterns work around a super-factory which creates other factories. Factory pattern provides a method of creating objects without specifying the exact class used to create it. So lets represent those as classes. Abstract Factory (Fábrica Abstracta) es un patrón de diseño para el desarrollo de software.Provee una interfaz para crear familias de objetos relacionados o dependientes entre … Since we are going to be. Dependency Injection 2018-06-19T16:22:26-06:00 OOP Lessons Learnt No Comment This is a frequent misunderstanding – Why use Dependency Injection when you can ask a factory for your object and have it returned to you? Benefits Achieved Through This Pattern: By applying Abstract Factory Pattern in the given scenario here, the code is made highly reusable and extensible. So we will work on it. Please read our previous article where we discussed the Factory Method Design Pattern in C# with an example. So in a new class, you implement this interface or abstract class (just like inheriting from a base class) and "override" In normal usage, the client software creates a concrete implementation of the abstract factory and then uses the generic interfaces to create the concrete objects that are part of the theme.
