What is the simple factory pattern?
Simple factory pattern describes a class that has one creation method with a large conditional that based on method parameters chooses which product class to instantiate and then return. In most cases, a simple factory is an intermediate step of introducing Factory Method or Abstract Factory patterns.
Can you explain the factory pattern?
A Factory Pattern or Factory Method Pattern says that just define an interface or abstract class for creating an object but let the subclasses decide which class to instantiate. In other words, subclasses are responsible to create the instance of the class.
What advantage a factory method provides that a simple factory is unable to?
Factory Method requires subclassing, but doesn’t require Initialize. The advantage of a Factory Method is that it can return the same instance multiple times, or can return a subclass rather than an object of that exact type. The new operator always creates an object, and fails to encapsulate object creation.
What does the simple factory design pattern do?
The simple factory design pattern is a form of abstraction, which hides the actual logic of an implementation of an object so the initialization code can focus on usage, rather than the inner workings.
When to use a factory pattern in C #?
Design patterns are reusable solutions to common problems in software design and factory design pattern is one of the common design patterns. In this article, we will learn what a factory design pattern is and how to implement a factory pattern in C#. We will also learn when to apply a factory design pattern in C# and .NET real-world applications.
Which is an example of an abstract factory pattern?
Abstract Factory Pattern. Unlike the above two patterns, an abstract factory is an interface to create of related objects without specifying/exposing their classes. We can also say that it provides an object of another factory that is responsible for creating required objects.
What are the three types of factory design?
There are three kinds of factory design patterns, namely, Simple Factory Pattern, Factory Method Pattern and Abstract Factory Pattern. We will understand these three patterns in detail by learning how to implement, when to implement and subsequently we will understand the differences between those.
