What separates master craftsmen from those still in the pursuit of mastery? Join us this Tuesday as we learn to identify the qualities that master craftsmen possess and how the rest of us can keep making progress on the path towards mastery.

In this session we will look at re-factoring some code that produces and outputs prime numbers.
There will be focus on finding buried the classes hidden with the the functions and extracting them as first class citizens.
This re-factoring will attempt to result in a number of small well named classes filled with small well named functions, as was described in the previous presentation
Clean Code → Functions

How big should a function be? 20 Lines? A screenful? Is there a way to know if your functions are the right size?

Object Oriented Design involves the art of breaking applications into classes. But have you found all the classes in the design of your application? Is there a way to know?

Functions are supposed to do "One Thing", do it well, and do it only. But what is "One Thing". Is there a way to tell if your functions are obeying that rule?

The answer to all these questions is yes! And not just with some fuzzy hand-waving platitudes either. There are fool-proof and unambiguous answers to these questions.

In this episode Uncle Bob (UB) shows you, in no uncertain terms, how to tell if your functions are the right size. He'll show you how to be certain that you've found all the classes in your design. He'll show you where they go to hide, and how to dig them out. And he'll show you what "One Thing" really means, and how to make sure your functions are doing one and only one thing.

This episode is loaded with code; but it's no screencast! Oh you'll see some screencasts, but not in the ordinary way -- not hardly. UB controls these screencasts -- he controls the audio, the video, the speed, and the magnification. He narrates and summarizes and points out the highlights. You'll see what you need to see, without waiting for the typing. In fact, UB compresses two hours of screencasts into three sessions totalling about twenty minutes. So it's a wild ride.

On that ride you'll learn why function size is so important to Object Oriented Design, and also just to plain old good programming. You'll learn the craftsman's way of writing and refactoring functions.
