In this article I'll complete the builder pattern, since I'll demonstrate how to define and use a form director class, in this way putting the final strokes on the example that you learned in the previous tutorial.
The tutorial goes back over a few of the concepts and code from the previous part of the series before getting into the form generation with these handy objects. They also show the FormBuilder class (creative name, eh?) that will generate the form's elements as created previously. They wrap it all up with the only new functionality - the Builder object Director class, creating a simple contact form.
