So, we have now completed the remodeling effort to get our anemic model into something more rich and more in line with the building blocks of a good DDD. Now, it's time to dive into the code implementation a little, so that you can understand how the code was written to support this model. If you look at the chapter3 code folder from the code distribution, you will notice that at the top level, it's divided into two root folders: bookstore-app-incomplete and bookstore-app-complete.

The EntityActor abstract class

The EntityActor abstract class defines the behaviors for our DDD entity actor classes. It's modeled as an FSM, where each of the...
