What is meant by Abstract Factory design pattern?

What is meant by Abstract Factory design pattern?

Abstract Factory Pattern says that just define an interface or abstract class for creating families of related (or dependent) objects but without specifying their concrete sub-classes. That means Abstract Factory lets a class returns a factory of classes. An Abstract Factory Pattern is also known as Kit.

What is the use of Abstract Factory pattern?

The Abstract Factory pattern helps you control the classes of objects that an application creates. Because a factory encapsulates the responsibility and the process of creating product objects, it isolates clients from implementation classes. Clients manipulate instances through their abstract interfaces.

What is factory and Abstract Factory design pattern?

Factory Method pattern is responsible for creating products that belong to one family, while Abstract Factory pattern deals with multiple families of products. Factory Method uses interfaces and abstract classes to decouple the client from the generator class and the resulting products.

Is abstract a pattern?

Abstract Factory design pattern is one of the Creational pattern. Abstract Factory pattern is almost similar to Factory Pattern is considered as another layer of abstraction over factory pattern. Abstract Factory patterns work around a super-factory which creates other factories.

Is abstract factory a design pattern?

Abstract Factory is a creational design pattern that lets you produce families of related objects without specifying their concrete classes.

How does an abstract factory work?

Abstract Factory patterns work around a super-factory which creates other factories. This factory is also called as factory of factories. In Abstract Factory pattern an interface is responsible for creating a factory of related objects without explicitly specifying their classes.

When can you apply abstract factory pattern?

When to Use Abstract Factory Pattern: The client is independent of how we create and compose the objects in the system. The system consists of multiple families of objects, and these families are designed to be used together. We need a run-time value to construct a particular dependency.

What is the difference between simple factory and factory method?

– A Simple factory is normally called by the client via a static method, and returns one of several objects that all inherit/implement the same parent. – The Factory Method design is really all about a “create” method that is implemented by sub classes. It normally uses the Factory Method to create the objects.

When should I use factory pattern?

The Factory Method pattern is generally used in the following situations:

1. A class cannot anticipate the type of objects it needs to create beforehand.
2. A class requires its subclasses to specify the objects it creates.
3. You want to localize the logic to instantiate a complex object.

What are the types of factory pattern?

We also discussed their four different types, i.e., Singleton, Factory Method, Abstract Factory and Builder Pattern, their advantages, examples and when should we use them.

How are abstract factory patterns used in design?

Abstract Factory patterns work around a super-factory which creates other factories. This factory is also called as factory of factories. This type of design pattern comes under creational pattern as this pattern provides one of the best ways to create an object. In Abstract Factory pattern an interface is responsible for creating a factory

How are abstract factories used in client software?

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 family of objects. The client does not know or care which concrete objects it gets from each of these concrete factories since it uses only the generic interfaces of their products.

How to create an abstract factory in C #?

In our example, it is the Speak method of the animal object. This is a class that implements the Abstract Factory interface (in our case Animal) to create concrete products. In our example, the Product classes are Cat, Lion, Dog, Octopus, and Sharp. Cat.cs: Create a class file with the name Cats.cs and then copy and paste the following in it.

How is an interface used in a factory pattern?

In Abstract Factory pattern an interface is responsible for creating a factory of related objects without explicitly specifying their classes. Each generated factory can give the objects as per the Factory pattern. We are going to create a Shape interface and a concrete class implementing it.
