What is the use of abstract factory?
The Abstract Factory pattern helps you control the classes of objects that an application creates. Because a factory encapsulates the responsibility and the process of creating product objects, it isolates clients from implementation classes. Clients manipulate instances through their abstract interfaces.
Is abstract factory useful?
Why do we use factory design pattern?
The Factory Method pattern is generally used in the following situations: A class cannot anticipate the type of objects it needs to create beforehand. A class requires its subclasses to specify the objects it creates. You want to localize the logic to instantiate a complex object.
When should we use factory method?
It is good idea to use factory methods inside object when:
- Object’s class doesn’t know what exact sub-classes it have to create.
- Object’s class is designed so that objects it creates were specified by sub-classes.
How is an abstract factory used in design?
Abstract Factory is a creational design pattern that lets you produce families of related objects without specifying their concrete classes.
How does the abstract factory pattern work in C #?
The Client uses the Abstract Factory and Abstract Product interfaces to create a family of related objects. So, modify the Main method as shown below. Abstract Factory Pattern provides an interface for creating families of related dependent objects without specifying their concrete classes.
How is an abstract factory used in UML?
The classes and objects participating in the above UML class diagram are as follow. This is an interface for operations which is used to create abstract product. This is a class which implements the AbstractFactory interface operations to create concrete products.
What does abstract mean in abstract design pattern?
Abstract means hiding some information and factory means which produces the products and pattern means a design. 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. When to use it Abstract Factory Design Pattern?
