Architecture, pattern detection, reengineering, Prolog, constraint satisfaction, template library
We show how to use constraint satisfaction for detecting design and architectural patterns in existing source code by using a pattern library. The patterns observer, pipe and-filter, interceptor, and blackboard are catalogued. Prolog has been used to detect these patterns by means of heuristics for class relations and method calls. A staged approach allows ranking the matching patterns by using a subset of the heuristics. The approach has been validated on two substantial subsystems of an Océ controller.
