Creational Design Patterns in Modern C++ - Parameterized Factory Method

The video tutorial explains the factory pattern, highlighting its limitations when adding new product types. It introduces the parameterized factory method as a solution, allowing the creation of multiple document types without needing corresponding application classes. The tutorial demonstrates implementing a document factory using a parameterized approach, refactoring code, and handling errors. It also discusses using static methods in the factory pattern to improve efficiency and reduce unnecessary instance creation. The tutorial concludes with a discussion on extending the factory method to support more document types in the future.
