CCEvovis A Clone Evolution Visualization System for Software

CCEvovis: A Clone Evolution Visualization System for Software Maintenance Hirotaka Honda Shogo Tokui Kazuki Yokoi Eunjong Choi Norihiro Yoshida Katsuro Inoue Software Engineering Laboratory, Department of Computer Science, Graduate School of Information Science and Technology, Osaka University

Maintenance of Code Clones [1] • Consistent modification Clone set A’ modify Code clones modify Vi Vi+1 • Refactoring (i. e. Merging code clones) Clone set B merge Code clones Vi call Vi+1 [1] Y.

Clone Notifier [1] • Code clone management system – To support code clone refactoring – Notify clone evolution between a pair of versions Detect Clones Vi Ci Detect Clones Categorize Clone Sets Map Clones Ci Ci+1 Mapped Clones Vi+1 Ci+1 Difficult to get information about the context of clone evolution [1] Y.
