For the ninth time now, the European Conference on Object-Oriented P- gramming provides a mid-summer gathering place for researchers, practitioners, students and newcomers in the field of object technology. Despite fierce c- petition from an increasing number of attractive conferences on object-related topics, ECOOP has successfully positioned itself as the premier European - ject technology conference. One reason is without doubt the composition of the conference week and the nature of its events. Running in parallel on the first two days, a comprehensive tutorial program and a very selective workshop program are offered to attendees. This is followed by a three-day technical p- gram organized in a single track providing a highly communicative atmosphere of scientific exchange and learning. Overlapping with these events are a two-day industrial exhibition and a two-day opportunity for non-industrial system dev- opers to demonstrate their software. Thus, ECOOP is not just a conference on programming but an event touching on the full spectrum of object technology. This volume constitutes the proceedings of the Ninth European Conference on Object-Oriented Programming, ECOOP, held in Aarhus, Denmark, August 7-11, 1995. Previous ECOOP conferences were held in Paris (France), Oslo (Norway), Nottingham (England), Ottawa (Canada, jointly with OOPSLA) , Geneva (Switzerland), Utrecht (the Netherlands) , Kaiserslautern (Germany) , and Bologna (Italy). Object technology continues to increase its impact on the corporate world.

This book constitutes the refereed proceedings of the 10th European Conference on Object-Oriented Programming, ECOOP '96, held in Linz, Austria, in July 1996. The 21 full papers included in revised version were selected from a total of 173 submissions, based on technical quality and originality criteria. The papers reflect the most advanced issues in the field of object-oriented programming and cover a wide range of current topics, including applications, programming languages, implementation, specification, distribution, databases, and design.

'When do the Lebesgue-Bochner function spaces contain a copy or a complemented copy of any of the classical sequence spaces?' This problem and the analogous one for vector- valued continuous function spaces have attracted quite a lot of research activity in the last twenty-five years. The aim of this monograph is to give a detailed exposition of the answers to these questions, providing a unified and self-contained treatment. It presents a great number of results, methods and techniques, which are useful for any researcher in Banach spaces and, in general, in Functional Analysis. This book is written at a graduate student level, assuming the basics in Banach space theory.

Following a 13-year tradition of excellence, the 14th ECOOP conference repeated the success of its predecessors. This excellence is certainly due to the level of maturity that object-oriented technology has reached, which warrants its use as a key paradigm in any computerized system. The principles of the object-oriented paradigm and the features of systems, languages, tools, and methodologies based on it are a source of research ideas and solutions to many in all areas of computer science. ECOOP 2000 showed a thriving eld characterized by success on the practical side and at the same time by continuous scienti c growth. Firmly established as a leading forum in the object-oriented arena, ECOOP 2000 received 109 high quality submissions. After a thorough review process, the program committee selected 20 papers, which well re?ect relevant trends in object-oriented research: object modeling, type theory, distribution and coo- ration, advanced tools, programming languages. The program committee, c- sisting of 31 distinguished researchers in object-orientation, met in Milan, Italy, to select the papers for inclusion in the technical program of the conference.

This book constitutes the refereed proceedings of the Second International Symposium on Object Technologies for Advanced Software, ISOTAS'96, held in Ishikawa, Japan, in March 1996. ISOTAS'96 was sponsored by renowned Japanese and international professional organisations. The 14 papers included in final full versions, together with the abstracts of four invited papers, were carefully reviewed and selected from a total of 56 submissions; they address most current topics in object software technology, object-oriented programming, object-oriented databases, etc. The volume is organized in sections on design and evolution, parallelism and distribution, meta and reflection, and evolution of reuse.

Purpose of the Book This book presents an approach to improve the standard object-oriented pro gramming model. The proposal is aimed at supporting a larger range of incre mental behavior variations and thus promises to be more effective in mastering the complexity of today's software. The ability of dealing with the evolutionary nature of software is one of main merits of object-oriented data abstraction and inheritance. Object-orientation allows to organize software in a structured way by separating the description of different kinds of an abstract data type into different classes and loosely connecting them by the inheritance hierarchy. Due to this separation, the soft ware becomes free of conditional logics previously needed for distinguishing between different kinds of abstractions and can thus more easily be incremen tally extended to support new kinds of abstractions. In other words, classes and inheritance are means to properly model variations of behavior related to the existence of different kinds of an abstract data type. The support for extensi bility and reuse with respect to such kind-specific behavior variations is among the main reasons for the increasing popularity of object-oriented programming in the last two decades. However, this popularity does not prevent us from questioning the real effec tiveness of current object-oriented techniques in supporting incremental vari ations. In fact, this popularity makes a critical investigation of the variations that can actually be performed incrementally even more important.

This book constitutes the refereed proceedings of the 12th European Conference on Object-Oriented Programming, ECOOP'98, held in Brussels, Belgium, in July 1998. The book presents 24 revised full technical papers selected for inclusion from a total of 124 submissions; also presented are two invited papers. The papers are organized in topical sections on modelling ideas and experiences; design patterns and frameworks; language problems and solutions; distributed memory systems; reuse, adaption and hardware support; reflection; extensible objects and types; and mixins, inheritance and type analysis complexity.

Pattern-oriented software architecture is a new approach to software development. This book represents the progression and evolution of the pattern approach into a system of patterns capable of describing and documenting large-scale applications. A pattern system provides, on one level, a pool of proven solutions to many recurring design problems. On another it shows how to combine individual patterns into heterogeneous structures and as such it can be used to facilitate a constructive development of software systems. Uniquely, the patterns that are presented in this book span several levels of abstraction, from high-level architectural patterns and medium-level design patterns to low-level idioms. The intention of, and motivation for, this book is to support both novices and experts in software development. Novices will gain from the experience inherent in pattern descriptions and experts will hopefully make use of, add to, extend and modify patterns to tailor them to their own needs. None of the pattern descriptions are cast in stone and, just as they are borne from experience, it is expected that further use will feed in and refine individual patterns and produce an evolving system of patterns.

\My tailor is Object-Oriented". Most software systems that have been built - cently are claimed to be Object-Oriented. Even older software systems that are still in commercial use have been upgraded with some OO ?avors. The range of areas where OO can be viewed as a \must-have" feature seems to be as large as the number of elds in computer science. If we stick to one of the original views of OO, that is, to create cost-e ective software solutions through modeling ph- ical abstractions, the application of OO to any eld of computer science does indeed make sense. There are OO programming languages, OO operating s- tems, OO databases, OO speci cations, OO methodologies, etc. So what does a conference on Object-Oriented Programming really mean? I honestly don’t know. What I do know is that, since its creation in 1987, ECOOP has been attracting a large number of contributions, and ECOOP conferences have ended up with high-quality technical programs, featuring interesting mixtures of theory and practice. Among the 183 initial submissions to ECOOP’99, 20 papers were selected for inclusion in the technical program of the conference. Every paper was reviewed by three to ve referees. The selection of papers was carried out during a t- day program committee meeting at the Swiss Federal Institute of Technology in Lausanne. Papers were judged according to their originality, presentation qu- ity, and relevance to the conference topics.

Originally published in 2002, this book presents techniques in the application of formal methods to object-based distributed systems. A major theme of the book is how to formally handle the requirements arising from OO distributed systems, such as dynamic reconfiguration, encapsulation, subtyping, inheritance, and real-time aspects. These may be supported either by enhancing existing notations, such as UML, LOTOS, SDL and Z, or by defining fresh notations, such as Actors, Pi-calculus and Ambients. The major specification notations and modelling techniques are introduced and compared by leading researchers. The book also includes a description of approaches to the specification of non-functional requirements, and a discussion of security issues. Researchers and practitioners in software design, object-oriented computing, distributed systems, and telecommunications systems will gain an appreciation of the relationships between the major areas of concerns and learn how the use of object-oriented based formal methods provides workable solutions.
