逆向工程中UML活动图的呈现技术研究

ynamic analysis is an important approach for understanding object-oriented systems with the characteristics of distribution and concurrency in reverse engineering. Recovering dynamic views according with UML standard from dynamic information has very important value for understanding complicated systems. The paper emphasizes on the research of the representation technology of UML activity diagram based on the dynamic information collected by dynamic analysis, presents the algorithm of activity diagram representation and discusses representation for fork type of dynamic information showing creating relations among processes and wait type of dynamic information showing synchronizing relations among processes and representation for inter-process communication relations based on object flow. Finally, the validity of the algorithm is verified by a practical system.
