Afterwards you are invited to a refreshment.

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. ___
