OCL exception handling

Abstract

Object Constraint Language (OCL) is part of the Unified Modeling Language (UML) specification and can be used to enforce constraints on the attributes or methods of a class. It would greatly help the software developers if such non-executable OCL constraints specified in a UML model could be enforced on the executable code generated from the model. This thesis discusses the concepts, ideas and the approach in transforming a model developed in the Rational Rose software with OCL constraints into Java code shells, complete with fragments of code to detect the run-time violations of the constraints. The implementation and testing of a prototype tool that incorporates these ideas is also discussed.
