Design Pattern Abstract Implementation

In this article i will discuss the concept of abstract factory design pattern in c and net and how to implement the abstract factory design pattern in c.

Design pattern abstract implementation. Accelerate your application development to where you can write entire solutions in just 33 days. In this example we ll create two implementations of the factory method design pattern. To support global operations we will require to enhance the system to support different car making styles for. Now imagine if our car maker decides to go global.

First we ll create a family of animal class and will later on use it in our abstract factory. Dofactory net includes the gang of four and enterprise patterns but also many other innovations including our ultra clean architecture powerful low code tactics rapid application development rad techniques and much more. Let see the. The abstract factory pattern provides a way to encapsulate a group of individual factories that have a common theme without specifying their concrete classes.

Builder pattern solves the issue with a large number of optional parameters and inconsistent state by providing a way to build the object step by step and provide a method that will actually return the final object. Elements of reusable object oriented software 1994 is a software engineering book describing software design patterns the book was written by erich gamma richard helm ralph johnson and john vlissides with a foreword by grady booch the book is divided into two parts with the first two chapters exploring the capabilities and pitfalls of object oriented programming and. In factory design pattern we discussed how to abstract the car making process for various car model types and their additional logic included in car making process. The classes that participate to the abstract factory pattern are.

This type of design pattern comes under creational pattern as this pattern provides one of the best ways to create an object. Abstractfactory declares a interface for operations that create abstract. Design global car factory using abstract factory pattern. Implementation the pattern basically works as shown below in the uml diagram.

So at runtime abstract factory is coupled with any desired concrete factory which can create objects of desired type. Abstract factory patterns work around a super factory which creates other factories. Abstract factory patterns work around a super factory which creates other factories. Here s the animal interface.

In normal usage the client software creates a concrete implementation of the abstract factory and then uses the generic interface of the factory to create the concrete objects that are part of the theme. Abstract factory offers the interface for creating a family of related objects without explicitly specifying their classes. After that we ll manage access to them using an abstract factory abstractfactory. Public interface animal string getanimal.

This pattern was introduced to solve some of the problems with factory and abstract factory design patterns when the object contains a lot of attributes.
