Abstract

Software artifacts usually have static program constraints and these constraints should be satisfied in each reuse. In addition to this, the developers are also required to satisfy the coding conventions used by their organization. Because in a complex software system there are too many coding conventions and program constraints to be satisfied, it becomes a cumbersome task to check them all manually. This paper presents a process and tools that allow computer-aided program constraint checking that work on the source code. We developed a modeling language called Source Code Modeling Language (SCML) in which program elements from the source code can be represented. In the process, the source code is converted into SCML models. The constraint detection is realized by graph transformation rules which are also modeled in SCML; the rules detect the violation and extract information from the SCML model of the source code to provide feedback on the location of the problem. The constraint violations can be queried from a querying mechanism that automatically searches the graph for the extracted information. The process has been applied to an industrial software system.
