Abstract:

Locating codes for software features efficiently and accurately is very important for software maintenance. The paper proposed an integrated approach to feature location in objectoriented (IAFLO) system, which uses software reconnaissance to build trace relations from features to classes, and regards these classes as seeds to construct concern graph for objectoriented program. Furthermore, under the slice criteria of attributes and statements in concern graph, the objectoriented slicing method was adopted to compute codes that directly affect features. The method has a high degree of automation, and can improve the efficiency of program understanding in software maintenance.
