Incremental OCL to C# code generation

In software engineering, modeling with UML and OCL became industry standards and are supported by many computer-aided software engineering tools. The increasing number of the modeled functionalities results in complex models that need more and more textual constraints to express the hidden restrictions applied to the systems. During the development of the metamodel, rebuilding all the constraints is unnecessary when only a few changes have been applied due to the iterative, incremental manner of modifications. In this paper, we present an algorithm that incrementally generates code from modified constraints, thus, the required rebuild operations are kept to a minimum. With the proposed method, the duration of metamodel development can be decreased, thus, the efficiency of the environment is improved.
