any derived class instance is a base class instance. This is important as factory method depends on “ is a” relationship that I have mentioned in some previous chapters. In this chapter, we will see factory method pattern, which is a creational design pattern, and what all we need to take care when using factories.įactory method is simply a static class method that aids in the instantiation of objects particularly belonging to a hierarchical class system.
Creational design pattern: Factory method in C++ I will discuss about some popular design patterns, their uses, C++ implementation, what all things we need to take care about their thread safety aspects, resource management and ownership aspect. There are many important design patterns and so, I have decided to start a series on design patterns. This chapter is the first part of a series on design patterns in C++.
Key Words: Design patterns in C++, Factory method in C++, creational design pattern
