OGAN: Visualizing object interaction scenarios based on dynamic interaction context

Visualizing an execution trace of an object-oriented system as sequence diagrams is effective to understand the behavior of the system. To support developers to understand concrete interaction among classes, our tool named OGAN extracts sequence diagrams representing interaction scenarios for a pair of classes specified by a user. OGAN classifies objects into groups based on their neighbor classes that directly interact with the objects, and visualizes interaction scenarios for each pair of object groups.
