Key Components of Factory Method Design Pattern
Product
- It’s an abstract class or interface that defines the common operations for the objects that the factory will create.
- Concrete Products are the actual classes that implement the Product interface, each representing a specific type of object to be created.
Creator
- It’s an abstract class or interface that declares the factory method.
- This method is responsible for creating Product objects, but it delegates the actual creation to subclasses.
Concrete Creators
- These are subclasses of the Creator that implement the factory method.
- They decide which specific Concrete Product to create, often based on input parameters or configuration.
Factory Method
- It’s a method defined in the Creator class that is responsible for creating Product objects.
- It’s typically declared as abstract in the Creator and implemented in the Concrete Creators.
