Chapter 13. Advanced Patterns
I hesitated when naming this chapter, Advanced Patterns. This isn't really about patterns that are more complicated or sophisticated than other patterns. It is about patterns that you wouldn't use very frequently. Frankly, coming from a static programming language background, some of them seem crazy. Nonetheless they are completely valid patterns and are in use within big name projects everywhere.
In this chapter we'll be looking at the following topics:
- Dependency injection
- Live post processing
- Aspect oriented programming
- Macros
Dependency injection
One of the topics we've been talking about continuously during this book is the importance of making your code modular. Small classes are easier to test, provide better reuse, and promote better collaboration for teams. Modular, loosely coupled code is easier to maintain, as changes can be limited. You may remember the example of a ripstop we used earlier.
With modular code of this sort we...
