Model-based Source Code Editing

Keywords: Program Comprehension, Model-driven development, Implementation, Class Diagrams, UML

Is there a difference between a program entity in source code or a model as presented in a UML class diagram?

We don't think so... In this approach

Model-based Source Code Editing generates UML-like views of classes, methods, and their relationships being involved in a specific test case. Based on such mid-level abstractions, developers can edit these models and the related source code is changed automatically in background.
