Precise specification to compound patterns with ExLePUS

Abstract

Prior research suggested modeling languages for precise specification of design pattern structures and behaviors. However, seldom has put effort on their integrations as well as their specifications. To provide a first class CASE support to the recognition, verification and application of design patterns as well as their compounds, a precise specification to their leitmotifs is critical. In this paper, we present the essentials of pattern integration and propose an extended version, we name it exLePUS, to a pattern specification language (LePUS) in order to support the specification of these essentials and thus compound patterns. A case study has illustrated how it is used a well-known compound pattern.
