Java Code Generation from Formal Models: The CO-OPN Framework

This document presents a framework for generating Java code from formal models. It discusses managing concurrency with Petri nets, modeling transactional systems with Concurrent Object-Oriented Petri Nets (CO-OPN), and the CO-OPN code generation framework. The tutorial aims to demonstrate the advantages of model-based development using formal models like Petri nets, including precise semantics, platform independence, and automatic model checking, testing and code generation.

Switzerland Petri Net: Definition • A Petri net is a directed bipartite graph (P, T, F, M): • P is a finite set of places • T is a finite set of transitions • P and T are disjoint, (P∩T =Φ) • F (P×T)∪(T×P) is the flow relation • Marking M is the distribution of tokens in the PN • Token is defined according to the type of PN 8

Switzerland Part I: Summary • PN for concurrent programming: 1. Use Petri net to design concurrent programs: threads, semaphores, locks, channels. Do model checking for liveness, deadlock-freedom, fairness etc. 2. Generate project skeleton from the correct PN model 3. Implement the functionalities of threads without thinking about concurrency • This principle only works with Place/Transition Nets • What is still missing: encapsulation, transactional behavior, system coordination 35
