What is Abstract Design factory?

What is Abstract Design factory?

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.

Where is abstract factory pattern used?

The purpose of the Abstract Factory is to provide an interface for creating families of related objects, without specifying concrete classes. This pattern is found in the sheet metal stamping equipment used in the manufacture of Japanese automobiles.

How does an abstract factory work?

Abstract Factory provides interfaces for creating families of related or dependent objects without specifying their concrete classes. 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.

Why this pattern is called abstract factory?

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.

What is difference between factory and Abstract Factory?

Factory: Creates objects without exposing the instantiation logic to the client. Abstract Factory: Provides an interface for creating families of related or dependent objects without specifying their concrete classes.

What is factory and Abstract Factory design pattern?

The main difference between factory pattern and abstract factory pattern is that the factory pattern provides a method of creating objects without specifying the exact class used to create it while the abstract factory pattern provides a method to combine a group of individual factories without specifying their …

When should I use Abstract Factory?

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 Abstract Factory and builder design patterns?

Builder focuses on constructing a complex object step by step. Abstract Factory emphasizes a family of product objects (either simple or complex). Builder returns the product as a final step, but as far as the Abstract Factory is concerned, the product gets returned immediately. Builder often builds a Composite.

How Abstract Factory pattern uses composition?

The Abstract factory pattern describes a method of individual fabrics composition, that are grouped together by some common criteria. This pattern includes four main roles: AbstractFactory — declares an interface for operations that create product object.

What is difference between Abstract Factory and 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.

What are the benefits of applying Abstract Factory design pattern?

The Abstract Factory pattern has the following benefits and liabilities:

• It isolates concrete classes.
• It makes exchanging product families easy.
• It promotes consistency among products.
• Supporting new kinds of products is difficult.

Which of the following describes the Abstract Factory pattern correctly?

In Factory pattern, we create object without exposing the creation logic to the client and refer to newly created object using a common interface. Q 8 – Which of the following is correct about Abstract Factory design pattern. A – This type of design pattern comes under creational pattern.

What is Factory Design Pattern with example?

This type of design pattern comes under creational pattern as this pattern provides one of the best ways to create an object. In Factory pattern, we create object without exposing the creation logic to the client and refer to newly created object using a common interface.

What is the difference between Abstract Factory and factory design patterns?

Which of the following are participants in the GOF abstract factory design pattern?

The following classes are the participants of this pattern: AbstractFactory — declares an interface for operations that create abstract products. ConcreteFactory — implements operations to create concrete products. AbstractProduct — declares an interface for a type of product objects.

What are the benefits of applying abstract factory design pattern?

What is abstract factory design pattern in Java?

Abstract Factory is a creational design pattern, which solves the problem of creating entire product families 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.

Which of the following are participants in the GOF prototype design pattern?

The classes participating to the Prototype Pattern are: Client – creates a new object by asking a prototype to clone itself. Prototype – declares an interface for cloning itself. ConcretePrototype – implements the operation for cloning itself.
