Abstract Factory Vs Factory Design Pattern C

Structural code in c.

Abstract factory vs factory design pattern c. Object creation has been abstracted and there is no need for hard coded class names in the client code. Abstract factory in c abstract factory is a creational design pattern which solves the problem of creating entire product families without specifying their concrete classes. Client interacts with factory only. Factory method design pattern here we define an interface which will expose a method which will create objects for us.

So the abstract factory pattern is a software design pattern that provides a way to encapsulate a group of individual factories that have a common theme. Factory pattern vs abstract factory pattern. Factory method pattern is a simplified version of abstract factory pattern. Abstract factory defines an interface for creating all distinct products but leaves the actual product creation to concrete factory classes.

Rather it will be some interface or may be an abstract class. Return type of that method is never a concrete type. Factory method and abstract factory design pattern are about creating objects. This structural code demonstrates the abstract factory pattern creating parallel hierarchies of objects.

While creating object you have to pass the concrete product class object from factory. When to use it abstract factory design pattern. The concretefactory object can be implemented as a singleton as only one instance of the concretefactory object is needed.
