In this chapter, I apply Alexander’s suggested approach1 with design patterns to solve the CAD/CAM problem presented in Chapter 3, “A Problem That Cries Out for Flexible Code.”
• Walks you through the methods needed to solve the earlier CAD/CAM problem.
• Takes you through the initial design phase. The details of implementation are left to you.
• Compares the new solution with the previous solution.
Chapter 3 described the requirements for the CAD/CAM problem, a real-world problem that first got me on the road to using design patterns.
The problem domain is in computer systems to support ...
