What is factory and abstract factory pattern?
The main difference between a “factory method” and an “abstract factory” is that the factory method is a single method, and an abstract factory is an object. The Factory Method pattern uses inheritance and relies on a subclass to handle the desired object instantiation.
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 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 are the elements of abstract method patterns?
Abstract Factory Design Pattern
- Intent. Provide an interface for creating families of related or dependent objects without specifying their concrete classes.
- Problem. If an application is to be portable, it needs to encapsulate platform dependencies.
- Discussion.
- Structure.
- Example.
- Check list.
- Rules of thumb.
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.
What is abstract patterns?
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.
