When a block of code grows too complex, you should decompose it, as implied by figure 8.1. Chapter 7 discussed where to take things apart. In this chapter, you’ll learn how to design the new parts.
Figure 8.1 Decompose a block of code into smaller blocks when it becomes too complex. How should the new blocks look? You’ll learn some principles of API design in this chapter.
You can decompose code in many ways. There isn’t a single correct way to do it, but there are more wrong ways than good ways. Staying on the narrow path of good API design requires skill and taste. Fortunately, the skill can be learned. Congruent with the theme ...
