Data Abstraction in AspectJ

Abstract

The AspectJ project[1] is exploring language support to enable programmers to implement crosscutting concerns in a modular fashion. Previous work in this area has primarily examined the expressiveness of AspectJ, to further aspect-oriented programming language research. In our work we focus on critical software engineering issues related to system modularity. In particular, we want to understand how use of AspectJ interacts with the well-known data abstraction principle[2].

In this abstract, we describe some of our work in identifying the explicit and implicit ways that modules can become dependent upon design decisions of another module in AspectJ. We hope that this information will provide a useful perspective to aspect-oriented programming language designers and will help users of AspectJ make informed design decisions. Given the space constraints, we must assume that the reader is familiar with the AspectJ language[1].
