What are abstract factory in creational design patterns?
Abstract Factory is a creational design pattern that lets you produce families of related objects without specifying their concrete classes.
When can you apply Abstract Factory pattern?
When to Use Abstract Factory Pattern: The client is independent of how we create and compose the objects in the system. The system consists of multiple families of objects, and these families are designed to be used together. We need a run-time value to construct a particular dependency.
What do you call an abstract factory pattern?
This factory is also called as factory of factories. This type of design pattern comes under creational pattern as this pattern provides one of the best ways to create an object. In Abstract Factory pattern an interface is responsible for creating a factory of related objects without explicitly specifying their classes.
What is the purpose of abstract factory in PHP?
Abstract Factory in PHP. Abstract Factory is a creational design pattern, which solves the problem of creating entire product families without specifying their concrete classes. Abstract Factory defines an interface for creating all distinct products but leaves the actual product creation to concrete factory classes.
How are concrete factories implemented in abstract factory?
Concrete Factories implement creation methods of the abstract factory. Each concrete factory corresponds to a specific variant of products and creates only those product variants. Although concrete factories instantiate concrete products, signatures of their creation methods must return corresponding abstract products.
How are abstract factories used in client software?
Client software creates a concrete implementation of the abstract factory and then uses the generic interfaces to create the concrete objects that are part of the family of objects. The client does not know or care which concrete objects it gets from each of these concrete factories since it uses only the generic interfaces of their products.
