Aspect-Oriented Reengineering of an Object-Oriented Library in a Short Iteration Agile Process
Source: University College Cork
Aspect-oriented re-engineering aims to modularize crosscutting concerns in an existing system using a new abstraction called an aspect. Code concerns may be tangled and scattered throughout an existing code base thus hampering maintenance. This paper describes the re-engineering of an object-oriented software library called GEF using aspect-oriented techniques as an integral activity in an agile process. Graph Editing Framework (GEF) is a medium-sized open source Java library for the construction of graph editing applications. The authors evaluated both the original and re-engineered code by applying a set of appropriate software metrics to measure to what extent aspect-oriented refactoring affected modularity attributes such as coupling, cohesion and complexity.
