1. Ptidej tool suite – Architecture
User Interface
Meta-model
Problem. Provide a sound architecture to model programs and to apply analyses, data conversion
algorithms, and third-party programs on the models.
Solution. The PADL meta-model (Pattern and Abstract-level Description Language) describes
programs. PADL sits on CPL (Common Ptidej Library), which provides basic services, and exports
extension points for different parsers and analyses.
The PtidejUI framework displays and interacts with models. PtidejUI provides a window managerindependent graphic library (AWT and SWT) and extension points for analyses and extensions.
Consequences. 4 parsers: AOL, AspectJ, C++, Java, 4 UI interfaces: Applet, AWT, Eclipse, Swing, and
4 add-ons: Aspects, DRAM, EPI, SAD.
