To specify both structural aspects and behavioral aspects of design patterns, we introduce traditional predicate logic combined with Alien's interval-based temporal logic as our theoretical foundation. Moreover, we take the Visitor pattern as an example to illustrate how to specify design patterns to support recovery of design patterns besides structural category. The experimental results show that the approach presented is practical for recovering design information of real world systems.展开更多
