Acknowledgments

Working on this book has been a great pleasure for all of the authors. Long discussions about local interfaces and dependent objects have resulted in several chapters being rewritten and then rewritten again, and changes in the specification have led to many interesting discussions and insights.

Without the active support of colleagues and friends, work on this book would not have been nearly so interesting, nor so productive. Stefan Denninger and Ingo Peters would like particularly to thank Stefan Schulze and Alexander Greisle, whose constructive and highly competent feedback have significantly improved the quality of this book. They would also like to thank the readers of the first German edition, whose support and feedback made the second edition possible. Finally, they wish to thank their editor, Martin Asbach, of Addison-Wesley, for his great care and friendly collaboration in bringing this book into the world, to the staff of Apress for making the English translation possible, and for their amiable and uncomplicated collaboration.

Rob Castaneda would like to thank John Zukowski, Grace Wong, and the team at Apress, as well as colleagues at CustomWare Asia Pacific, including Ian Daniel, Nathan Lee, and Scott Babbage, as well as his wife, Aimee Castaneda. Without the support of the these individuals, this work would not have been achievable.
