Book Description
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.

Book Description
Software systems play an increasingly important role in modern societies. Smart cards for personal identi?cation, e-banking, software-controlled me- cal tools, airbags in cars, and autopilots for aircraft control are only some examples that illustrate how everyday life depends on the good behavior of software. Consequently, techniques and methods for the development of hi- quality, dependable software systems are a central research topic in computer science. A fundamental approach to this area is to use formal speci?cation and veri?cation. Speci?cation languages allow one to describe the crucial p- perties of software systems in an abstract, mathematically precise, and implementation-independent way. By formal veri?cation, one can then prove that an implementation really has the desired, speci?ed properties. Although this formal methods approach has been a research topic for more than 30 years, its practical success is still restricted to domains in which devel- ment costs are of minor importance. Two aspects are crucial to widen the application area of formal methods: – Formal speci?cation techniques have to be smoothly integrated into the software and program development process. – The techniques have to be applicable to reusable software components. This way, the quality gain can be exploited for more than one system, thereby justifying the higher development costs. Starting from these considerations, Peter Muller ̈ has developed new te- niques for the formal speci?cation and veri?cation of object-oriented so- ware. The speci?cation techniques are declarative and implementati- independent. They can be used for object-oriented design and programming.

Book Description
This book – inspired by two ECOOP workshops on exception handling - is composed of five parts; the first four address exception handling and related topics in the context of programming languages, concurrency and operating systems, pervasive computing systems, and requirements and specifications. The last part offers case studies, experimentation and qualitative comparisons. The 16 coherently written chapters by leading researchers review a wide range of issues in exception handling.

Book Description
In the past two years, the Smalltalk and Java in Industry and Education C- ference (STJA) featured a special track on generative programming, which was organized by the working group \Generative and Component-Based Software Engineering" of the \Gesellschaft fur ̈ Informatik" FG 2.1.9 \Object-Oriented Software Engineering." This track covered a wide range of related topics from domain analysis, software system family engineering, and software product - nes, to extendible compilers and active libraries. The talks and keynotes directed towards this new software engineering paradigm received much attention and - terest from the STJA audience. Hence the STJA organizers suggested enlarging this track, making it more visible and open to wider, international participation. This is how the GCSE symposium was born. The rst GCSE symposium attracted 39 submissions from all over the world. This impressive number demonstrates the international interest in generative programming and related elds. After a careful review by the program comm- tee, fteen papers were selected for presentation. We are very grateful to the members of the program committee, all of them renowned experts, for their dedication in preparing thorough reviews of the submissions. Special thanks go to Elke Pulvermuller ̈ and Andreas Speck, who proposed and organized a special conference event, the Young Researches Workshop (YRW). This workshop provided a unique opportunity for young scientists and Ph.D.

Book Description
Component-based software development is the next step after object-oriented programmingthatpromisesto reducecomplexityandimprovereusability.These advantages have also been identi?ed by the industry, and consequently, over the past years, a large number of component-based techniques and processes have been adopted in many of these organizations. A visible result of this is the number ofcomponentmodels thathavebeendevelopedandstandardized.These models de?ne how individual software components interact with each other and simplify the design process of software systems by allowing developers to choose from previously existing components. The development of component models is a ?rst step in the right direction, but there are many challenges that cannot be solved by the development of a new component model alone. Such challengesare the adaptation of components, and their development and veri?cation. Software Composition is the premiere workshop to advance the research in component-based software engineering and its related ?elds. SC 2005 was the fourth workshop in this series. As in previous years, SC 2005 was organized as an event co-located with the ETAPS conference. This year’s program consisted of a keynote on the revival of dynamic l- guages given by Prof. Oscar Nierstrasz and 13 technical paper presentations (9 full and 4 short papers). The technical papers were carefully selected from a total of 41 submitted papers. Each paper was thoroughly peer reviewed by at leastthreemembers oftheprogramcommittee andconsensusonacceptancewas achieved by means of an electronic PC discussion. This LNCS volume contains the revised versions of the papers presented at SC 2005.

Book Description
Attacks against computer systems can cause considerable economic or physical damage. High-quality development of security-critical systems is difficult, mainly because of the conflict between development costs and verifiable correctness. Jürjens presents the UML extension UMLsec for secure systems development. It uses the standard UML extension mechanisms, and can be employed to evaluate UML specifications for vulnerabilities using a formal semantics of a simplified fragment of UML. Established rules of security engineering can be encapsulated and hence made available even to developers who are not specialists in security. As one example, Jürjens uncovers a flaw in the Common Electronic Purse Specification, and proposes and verifies a correction. With a clear separation between the general description of his approach and its mathematical foundations, the book is ideally suited both for researchers and graduate students in UML or formal methods and security, and for advanced professionals writing critical applications.

Book Description
The size, complexity, and integration level of software systems is increasing c- stantly. Companies in all domains identify that software de?nes the competitive edge of their products. These developments require us to constantly search for new approaches to increase the productivity and quality of our software - velopment and to decrease the cost of software maintenance. Generative and component-based technologies hold considerablepromise with respect to achi- ing these goals. GCSE 2001 constituted another important step forward and provided a platform for academic and industrial researchers to exchange ideas. These proceedings represent the third conference on generative and com- nent-based software engineering. The conference originated as a special track on generative programming from the Smalltalk and Java in Industry and - ucation Conference (STJA), organized by the working group “Generative and Component-Based Software Engineering” of the “Gesellschaft fur ̈ Informatik” FG 2.1.9 “Object-Oriented Software Engineering.” However, the conference has evolved substantially since then, with its own, independent stature, invited speakers, and, most importantly, a stable and growing community. This year’s conference attracted 43 submissions from all over the world, - dicating the broad, international interest in the research ?eld. Based on careful review by the program committee, 14 papers were selected for presentation. I would like to thank the members of the program committee, all renowned - perts, for their dedication in preparing thorough reviews of the submissions.

Book Description
Invasive software composition as a new, component-based way to construct software systems is presented. To improve reuse, this method regards software components as greybox and integrates them during composition. Components are distinct in design, but are merged in implementations, leading to highly integrated and more efficient systems. Building on a minimal set of program transformations, composition operator libraries can be developed that parameterize, extend, connect, mediate, and aspect-weave components. Invasive software composition unifies several software engineering techniques such as generic programming, architecture systems, inheritance, and aspect-oriented programming. The book is centered around the JAVA language and a freely available demonstrator library called COMPOST. The book provides a wealth of material for researchers, students and professional software architects alike.
