UML Diagrams

Many of the diagrams in this book use the UML (Unified Modeling Language) standard. In particular, activity diagrams, deployment diagrams, class diagrams, the state diagrams are used to describe important concurrency architectures and class relationships. Although a knowledge of the UML is not necessary, familarity is helpful. Appendix A contains an explanation and description of the UML symbols and language that we use in this book.

Program Profiles

Each complete program in the book is accompanied by a program profile. The profile will contain implementation specifics such as headers required, libraries required, compile instructions, and link instructions. The profile also includes a Notes section that will contain any special considerations that need to be taken when executing the program. Code that is not accompanied by a profile is meant for exposition purposes only.

Sidebars

We made every attempt to stay away from notation that is too theoretical for a introductory book such as this one. However, in some cases the theoretical or mathematical notation was unavoidable. In those cases we use the notation but we provide a detailed explanation of the notation in a sidebar.
