Summary
In this chapter, we explored our first GoF design patterns. These patterns expose some of the essential basis of software engineering, not necessarily the patterns themselves, but the concepts behind them:
- The Strategy pattern is a behavioral pattern that we use to compose most of our future classes. It allows swapping behavior at runtime by composing an object with smaller pieces and coding against interfaces, following the SOLID principles.
- The Abstract Factory pattern brings the idea of abstracting away object creation, leading to a better separation of concerns. More specifically, it aims to abstract the creation of object families and follow the SOLID principles.
- Even if we defined it as an anti-pattern, the Singleton pattern brings the application-level objects to the table. It allows creating a single instance of an object that lives for the whole lifetime of a program. The pattern itself violates most SOLID principles.
