A Library-Based Approach To Translating Ocl Constraints To Jml Assertions For Runtime Checking, Carmen Avila, Guillermo Flores, Jr., Yoonsik Cheon

Departmental Technical Reports (CS)

OCL is a formal notation to specify constraints on UML models that cannot otherwise be expressed by diagrammatic notations such as class diagrams. Using OCL one can document detailed design decisions and choices along with the behavior, e.g., class invariants and method pre and postconditions. However, OCL constraints cannot be directly executed and checked at runtime by an implementation, thus constraint violations may not be detected or noticed, causing many potential development and maintenance problems. In this paper we propose an approach to checking OCL constraints at runtime by translating them to executable JML assertions. The key components of our …
