Abstract ======== Aspect-oriented programming languages usually are extensions of object-oriented ones, and their compilation target is usually the (virtual) machine model of the language they extend. While that model elegantly supports core object-oriented language mechanisms such as virtual method dispatch, it provides no direct support for core aspect-oriented language mechanisms such as advice application. Hence, current implementations of aspect-oriented languages bring about insufficient and inelegant solutions. The talk introduces a lightweight, object-based machine model for aspect-oriented languages based on object-oriented ones. It is centered around delegation and relies on a very dynamic notion of join points as loci of late-bound dispatch of functionality. The model is shown to naturally support an important number of aspect-oriented language mechanisms. The state of a first proof-of-concept implementation of the model is also presented. ___ Bio === Michael Haupt is a post-doctoral researcher in the Software Architecture Group at Hasso Plattner Institute, Potsdam. His work deals with implementing aspect-oriented programming languages and improving modularity in virtual machine implementations. Michael holds a doctoral degree from Technische Universität Darmstadt, where he started working on virtual machine support for aspects. ___ ----------------------------------------------------------------------- REGISTRATION ------------ Please DO NOT reply to this e-mail!

13 Sep '07

Registration is now open for the CHOOSE Forum 2007 on Languages for the Web. This year's CHOOSE Forum brings together a select group of speakers to provide us with a current snapshot of some of the key technologies available today. The morning is dedicated to shorter talks, while the afternoon session will consist of 3 in-depth presentations and tutorials. The day also includes the CHOOSE General Assembly, including reports from the President and the Treasurer, and elections for the CHOOSE Executive Board. http://www.choose.s-i.ch/Events/forum2007.html --- Reminder: CHOOSE Talk, Sept. 17, 2007, University of Bern Prof. Robert Hirschfeld — Expressing Context-dependent Behavioral Variations with Context-oriented Programming http://www.choose.s-i.ch/sigbeer.html Please register by email for this talk. --- Oscar Nierstrasz

Abstract ======== Context-oriented Programming, or COP, provides programmers with dedicated abstractions and mechanisms to concisely represent behavioral variations that depend on execution context. By treating context explicitly, and by directly supporting dynamic composition based on it, COP allows programmers to better express software entities that adapt their behavior late-bound, at runtime. Our presentation will illustrate COP constructs, their application, and their implementation, as well the relationship of COP to other approaches such as feature-oriented and aspect-oriented programming. We use Squeak as a programming environment to demonstrate sample scenarios. Bio === Robert Hirschfeld is a Professor of Computer Science at the Hasso- Plattner-Institut in Potsdam. There he leads the Software Architecture Group that is concerned with fundamental elements and structures of software, developing methods and tools for improving the comprehension and design of complex systems. Robert Hirschfeld was a senior researcher with DoCoMo Euro-Labs, the European research facility of NTT DoCoMo Japan, where he worked on infrastructure components for next generation mobile systems with a focus on dynamic service adaptation and aspect-oriented programming. Prior to joining Euro-Labs, he was a principal engineer at Windward Solutions in Sunnyvale, California. Robert Hirschfeld received a Ph.D. in Computer Science form the Technical University of Ilmenau, Germany. ----------------------------------------------------------------------- REGISTRATION ------------ Please DO NOT reply to this e-mail!
