Amida: a Sequence Diagram Extraction Toolkit for Java


OGAN, a tool presented in ICPC 2009, is available here. OGAN allows you to focus on interactions between a pair of classes rather than the whole execution trace.

What is Amida?

Amida is a toolkit to record an execution trace of a Java program and visualize the trace as a sequence diagram.

Amida comprises a profiler that records an execution trace of a Java program and a viewer that visualizes the trace as a sequence diagram.

The Amida Viewer implements algorithms to detect loops and recursive calls in an execution trace. The viewer also supports our novel approach to efficiently detecting phases; the algorithm precisely divides a long execution trace into a series of smaller diagrams corresponding to features (or tasks to achieve a feature).

Amida User's Guide describes the details of the tool.
