Abstract Factory Design Pattern Code Project

Again here method return types will be generic interfaces.

Abstract factory design pattern code project. Factory pattern is one of the types of creational patterns. The abstract factory pattern extends the factory method pattern by allowing more types of objects to be produced. Factory method pattern is introduced in gang of four gof book and falls in the category of creational patterns. Advantages of factory method pattern.

Part 3 abstract factory pattern what is factory method pattern. Structural code in c. Abstract factory pattern can be use along with factory method pattern if needed. In abstract factory we define an interface which will create families of related or dependent objects.

Below is a code snippet of a client which has different types of invoices. Download source code 122 kb. The abstract factory design pattern is merely an extension of the factory method pattern which allows you to create objects without being concerned about the actual class of the objects being produced. Also for creating this families of objects we do not requires the class name.

This structural code demonstrates the abstract factory pattern creating parallel hierarchies of objects. In simple words interface will expose multiple methods each of which will create some object. There are three kinds of factory design patterns namely simple factory pattern factory method pattern and abstract factory pattern. It provides different kind of factories.

In this article series we will learn about different factory design patterns. Following is the definition of factory method pattern is taken from the same book. In abstract factory pattern an interface is responsible for creating a factory of related objects without explicitly specifying their classes. Each factory will create a particular kind of related objects.

This type of design pattern comes under creational pattern as this pattern provides one of the best ways to create an object. It basically provides a wayinterface for creating groups of object or you can say families of object which are inter dependent or of similar types. Aka drd and his adventures in software design 14592639 members. Object creation has been abstracted and there is no need for hard coded class names in the client code.

You can make out from the name factory itself its meant to construct and create something. Simple factory pattern and factory method pattern provide one kind on objects only in our examples all those objects were of type ifan. Thats why sometime we call abstract factory pattern as factory of factories.
