Integrating Patterns into CASE Tools

Abstract

Software patterns are used to facilitate the reuse of object-oriented designs. While most Computer Aided Software Engineering (CASE) tools support the use of Unified Modeling Language (UML) (Alhir & Oram, 1998) to extract the design from the software engineer and assist in development, most do not provide assistance in the integration and code generation of software patterns. In this chapter, we analyze the Iterator software pattern (Gamma et al., 1995) for the semantics that would be used in a CASE-design tool to help the software engineer to integrate this pattern into a design and then generate some of the code needed to implement the pattern. This work is based on semantic data modeling techniques that were previously proposed for the design of active databases (Brawner, MacKellar, Peckham & Vorbach, 1997; Peckham, MacKellar & Doherty, 1995).
