《Java Modeling in Color with UML-chapter1》.pdf

Pink is my favorite crayon. Aerosmith 1 Archetypes, Color, and the Domain-Neutral Component Color profoundly affects how we see the world around us. Just as the transition from black-and-white photography to color is so profound, the transition from black-and-white modeling is an awesome one. Welcome to the world of modeling with archetypes, color, a domain-neutral component, and a dozen domain-specific compound components. In this chapter, youll learn and apply archetypes, color, and the domain-neutral component. In Chapters 2-5, youll read and apply domain-specific components. In Chapter 6, youll discover feature-driven development, the process for all of this into best practice. This book focuses on modeling with color, archetypes, and components—along with a process for putting it into practice. How does Java fit in? The model shapes are Java inspired. Youll find composition rather than inheritance. Youll also see a judicious use of interface plug-in points—for added flexibility. In addition, the CD includes all of the models including Java skeleton source code. Weve developed this book as a front-end companion to Java Design. That book delivers specific strategies for designing with composition, designing with threads, and designing with notification. Examples throughout this book use Unified Modeling Language (UML) notation. Class-diagram notation and some conventions used in this book are shown in Figure 1-1. Sequence-diagram notation and some conventions used in this book are shown in Figure 1-2. We suggest you scan those figures now, then refer back to them from time to time along the way. 1.1 Archetypes Now lets turn our attention to this chapters first major topic: archetypes. Page 1
