Abstract

Using only traditional techniques the implementation of concerns like exception handling, multi-object protocols, synchronization constraints, and security policies tends to be spread out in the code. The lack of modularity for these concerns makes them more difficult to develop and maintain. This tutorial shows how to use Aspect-oriented programming (AOP) [2, 3] to implement concerns like these in a concise modular way. We discuss the effect aspects have on software design and on code modularity. The concrete examples in the tutorial use AspectJ [1], a freely available aspect-oriented extension to the Java™ programming language.
