Untangling
Ran Ettinger, Mathieu Verbaere · 2004
Separation of concerns in existing code can be achieved by specific refactoring techniques. Modern refactoring tools support a number of well-known refactoring transformations, including method extraction. In this paper, we examine how method extraction can be improved through program slicing. Furthermore, we show how a generalization of such slice extraction can be applied to untangle existing code by extracting aspects.
