Principles and Design Rationale of Composition Filters

Bergmans, L.M.J. and Ak┼čit, M.

A wide range of aspect-oriented programming languages has appeared in the past years [7]. Current research on future generation AOP languages is addressing issues like flexibility, expressive power and safety. We think that it is important to understand the motivations and design decisions of the first generation AOP languages. The composition filters model [1, 7, 12] is one example of such a first-generation AOP language. The goal of this chapter is two-fold: first, it aims at explaining the principles of composition filters, in particular its aspect-oriented composition capabilities. Second, we aim to provide insight into the motivations and design rationale decisions behind the composition filters model.
