Sub-clone refactoring in open source software artifacts
Robert Tairas, Jeff Gray · 2010
We present a study of revisions made to open source projects that documents the actual refactoring of code associated with code clones (i.e., sections of duplicated code). The study identifies a characteristic in which some clone refactorings were performed on only part of the clone (i.e., a sub-clone). We conclude that sub-clones should be considered during the clone maintenance activity.
