One of the goal of my Ph.D. thesis and of my research work is the formalisation of bad design patterns to detect them in random Java code, and then to improve the corresponding code. Lot of studies are being made on the formalisation of design patterns, to extract them, to transform them and to generate them. This problem is deeply related to my studies.

In this context, I am currently working at some enhancements of a meta-model to describe design patterns. This meta-model has been defined and implemented by Hervé Albin-Amiot, also Ph.D. from École des Mines of Nantes. From this meta-model, I have implemented a framework for the visual display of design patterns.

You can find beneath: the implementation of the meta-model (PatternsBox), the graphic framework (JTU), and a detailed presentation of the meta-model and its goals and limitations.

A demo of the Repository Viewer is available for Palm Pilot. This demo demonstrate the compliance of the JTU graphical framework implementation to the standards. In fact, it required not to use some features of AWT because the Palm implementation of AWT is minimum.
