A differencing algorithm for object-oriented programs
During software evolution, information about changes between different versions of a program is useful for a number of software engineering tasks. For many of these tasks, a purely syntactic differencing may not provide enough information for the task to be performed effectively. This problem is esp...

description | During software evolution, information about changes between different versions of a program is useful for a number of software engineering tasks. For many of these tasks, a purely syntactic differencing may not provide enough information for the task to be performed effectively. This problem is especially relevant in the case of object-oriented software, for which a syntactic change can have subtle and unforeseen effects. We present a technique for comparing object-oriented programs that identifies both differences and correspondences between two versions of a program. The technique is based on a representation that handles object-oriented features and, thus, can capture the behavior of object-oriented programs. We also present JDIFF, a tool that implements the technique for Java programs, and empirical results that show the efficiency and effectiveness of the technique on a real program. |
