Vol: 48(62) No: 2 / June 2003 Implementation of OFL Modifiers Assertions D. Pescaru Department of Computer Science, "Politehnica" University of Timisoara, Faculty of Automation and Computers, Bd. V. Parvan no 2, Timisoara, Romania, e-mail: dan@cs.utt.ro, web: http://www.cs.utt.ro/~dan Keywords: assertions, object oriented programming, OFL, OCL, meta-programming. Abstract The OFL Model is a meta-model for object oriented programming languages. It provides customization of main aspects of the semantics of a language through actions and parameters. Further experience points out the necessity to capture more of the semantics of these languages. This goal is achieved by adding new elements to the original OFL Model. These elements are called OFL Modifiers. The most important part of a modifier definition resides in its associated assertion. This paper proposes a way to implement assertions for OFL Modifiers using OCL language. References [1] R. Chignoli, P. Crescenzo and P.
