What is factory and Abstract Factory pattern demonstrate with example?
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 the key strategy in the Abstract Factory?
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.
When should we use 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 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.
What is Abstract Factory design?
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. 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.
How does abstract factory pattern work?
What design issues does abstract factory pattern address?
The Abstract Factory design pattern describes how to solve such problems: Encapsulate object creation in a separate (factory) object. That is, define an interface (AbstractFactory) for creating objects, and implement the interface.
What is Abstract Factory used for?
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.
What is abstract factory design?
Does abstract factory use factory method?
Abstract factories are usually implemented using (a set of) factory methods. Abstract Factory pattern uses composition to delegate the responsibility of creating an object to another class while Factory Method design pattern uses inheritance and relies on a derived class or subclass to create an object.
Is abstract factory a factory of factories?
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.
Which is an example of an abstract factory?
Abstract Factory is a creational design pattern that lets you produce families of related objects without specifying their concrete classes. Imagine that you’re creating a furniture shop simulator. Your code consists of classes that represent: A family of related products, say: Chair + Sofa + CoffeeTable. Several variants of this family.
How does client use AbstractFactory and abstractproduct?
Client- uses the interfaces declared by the AbstractFactory and AbstractProduct classes. The AbstractFactory class is the one that determines the actual type of the concrete object and creates it, but it returns an abstract pointer to the concrete object just created.
Which is the best example of a code of conduct?
5 Effective Code Of Conduct Examples 1 Starbucks. Starbucks empowers all partners to make decisions that impact our reputation. 2 Google. The Google Code of Conduct is one of the ways we put Google’s values into practice. 3 Facebook. 4 Coca-Cola. 5 Microsoft.
How does the abstract factory pattern work in Java?
The pattern basically works as shown below, in the UML diagram: The classes that participate to the Abstract Factory pattern are: AbstractFactory- declares a interface for operations that create abstract products. ConcreteFactory- implements operations to create concrete products.
