Abstract

Aspect-Oriented Programming is an emerging programming paradigm providing novel constructs that eliminate code scattering and tangling by modularizing crosscutting concerns in their own aspect modules. Many current aspect-oriented languages are backwards compatible extensions to existing popular languages, which opens the way to aspectize systems written in those languages. This paper contributes with the beginnings of a pattern language for refactoring existing systems into aspect-oriented versions of those systems. The pattern language covers the early assessment and decision stages: identifying latent aspects in existing systems, knowing when it is feasible to refactor to aspects and assessment of the necessary prerequisites for the refactoring process.
