Objects, Components, Models and Patterns: 47th International Conference, TOOLS EUROPE 2009, Zurich, Switzerland, June 29-July 3, 2009, Proceedings . in Business Information Processing (33))

For the past 20 years the TOOLS conferences have continuously spread new technologies in the world of object-orientation, component technology and so- ware engineering in general. They constitute a particularly important forum for software researchers and practitioners to present work that relies on producing tools. This year's TOOLS continued the tradition and presented a strong program thatincluded originalcontributionsin allmajor?elds ofthe object-orientedp- adigm. As in TOOLS 2008, the concept of model occupied a considerable place; but other topics such as re?ection, aspects, modelling languages, debugging, and virtual machines design were also strongly represented. While most conferences had a decrease in the number of submitted papers, TOOLS made the choice of quality and decided to lower its acceptance rate to 25%, asa ?xedmaximumannouncedin the Callfor Papers.Out of67submitted contributions, the reviewing process led to the selection of 17 as full papers. For the ?rst time, two short papers were also accepted for presentation at the conference.

This book constitutes the thoroughly refereed proceedings of the 47th International Conference on Objects, Components, Models and Patterns, TOOLS EUROPE 2009, held in Zurich, Switzerland, in June/July 2009.

TOOLS has played a major role in the spread of object-oriented and component technologies. It has now broadened its scope beyond the original topics of object technology and component-based development to encompass all modern, practical approaches to software development. At the same time, TOOLS has kept its traditional spirit of technical excellence, its acclaimed focus on practicality, its well-proven combination of theory and applications, and its reliance on the best experts from academia and industry.

The 17 regular papers and two short papers presented in this book, together with two invited papers, were carefully reviewed and selected from 67 submissions.

The topics covered in this volume are reflection and aspects, models, theory, components, monitoring, and systems generation.
