Design Patterns: Structural
In this chapter, we will continue our look at design pattern, focusing on structural design patterns. Where the creational design patterns we looked at in the previous chapter center on object creation, structural design patterns help you combine objects together into a larger, more structured code base. They are flexible, maintainable, extensible, and ensure that if one part of your system changes, you do not need to completely rewrite the rest to suit. Structural design patterns can also be used to help interface with other code structures that you need to work together easily with in your application. Let’s look together at eight structural design patterns you may find useful in your code, together with examples.
