Abstract Factory Method Pattern
The Abstract Factory Pattern is a creational design pattern in object-oriented programming that provies an interface for creating families of related or dependent objects without specifying their concrete classes. It’s a higher-level pattern compared to the Factory Method Pattern, where you have not just one factory but a family of factories that work together to create related objects.
Explanation with Real World Example
Let’s consider a real-world example of a furniture manufacturer. This manufacturer produces various types of furniture sets, such as modern and vintage sets. Each set consists of several pieces of furniture, including a table, chiars, and a sofa. In this context:
- Abstract Factory: The abstract factory represents the furniture factory, which defines methods for creating different types of furniture products.
- Concrete Factories: There are two concrete factories – ModernFurnitureFactory and VintageFurnitureFactory. Each of these factoreis creates a complete set of furniture in a consistent style.
- Product Families: The product families are the sets of furniture (e.g., modern or vintage) with individual objects (e.g., table, chairs, sofa).
The Abstract Factory Pattern is used when you need to ensure that the created objects are compatible and belong to a consistent family.
Design Patterns in Object-Oriented Programming (OOP)
Software Development is like putting together a puzzle. Object-oriented programming (OOP) is a popular way to build complex software, but it can be tricky when you face the same design problems repeatedly. That’s where design patterns come in.
Design patterns are like well-known recipes for common problems in software development. They’re not step-by-step instructions, but more like guidelines to help you solve these problems in a flexible and efficient way. These patterns gather the wisdom of the software development community, making it easier for developers to work together and create software that’s easy to maintain, adapt, and reuse.
