Abstract

This tutorial teaches pragmatic aspect-oriented design (AOD) principles geared for “production” software, where long-term maintenance and evolution are important. The examples and group exercises use Java/AspectJ and Ruby, allowing us to compare and contrast AOD in statically- and dynamically-typed languages.

The tutorial starts with a review of the typical problems developers encounter using AOSD. With this motivation, the tutorial presents a set of strategies, design principles, and patterns for addressing those problems. The design principles are extensions to established object-oriented principles that support designing aspect software that is robust, maintainable, and reusable. Guidelines for when to use aspects vs. other techniques are covered. The tutorial concludes with a look forward to ways that aspects could improve frameworks and application architectures.

The tutorial includes several detailed examples and group exercises.
