Factory Pattern

Intent

• creates objects without exposing the instantiation logic to the client.
• refers to the newly created object through a common interface

Implementation

Factory Implementation - UML Class Diagram

The implementation is really simple

• The client needs a product, but instead of creating it directly using the new operator, it asks the factory object for a new product, providing the information about the type of object it needs.
• The factory instantiates a new concrete product and then returns to the client the newly created product(casted to abstract product class).
• The client uses the products as abstract products without being aware about their concrete implementation.
