The creational design patterns deal with object creation mechanisms. Their purpose is to create objects in a way that is suitable to the current situation, which could lead to unnecessary complexity and the need for extra knowledge if they were not there. The main ideas behind the creational design patterns are as follows:
- Knowledge encapsulation about the concrete classes
- Hiding details about the actual creation and how objects are combined
We will be focusing on the following creational design patterns in this book:
- The abstract factory design pattern
- The factory method design pattern
- The lazy initialization design pattern
- The singleton design pattern
- The object pool design pattern
- The builder design pattern ...
