Modeling four aspect-oriented programming mechanisms shows the way in which each supports modular crosscutting. Comparing the models produces a clear three part characterization of what is required to support crosscutting structure: a common frame of reference that two (or more) programs can use to connect with each other and each provide their semantic contribution.

This paper briefly describes the design of a dynamic adaptation management framework exploiting the concepts provided by Aspect-Oriented Software Development (AOSD) -in particular Aspect-Oriented Programming (AOP)-, as well as reflection and adaptation techniques in order to support and speed up the process of dynamic component evolution by tackling issues related to signature and protocol inte...

For concrete usage scenarios there are different options of how to use AspectJ's language features, and these options deeply impact the chances for further evolution of both base classes and aspects. Aspects can use aspect-oriented as well as object-oriented features. The combination of these mechanisms provides new powerful mechanisms. Idioms can help in guiding AspectJ users through this fron...

In this paper we show how design-level aspects can be used to encapsulate security concerns that can be woven into models of software designs. The aspect-oriented design technique described in this paper allows one to analyze the impact of security concerns on other functional concerns. We illustrate our technique using a small example.
