Graph Transformation Based Description Language for Model Refactorings

Abstract

提出了一种基于图转换的模型重构描述语言.针对模型重构的特征,设计了模型重构描述语言的基本元素,并给出了如何通过这些基本元素描述模型重构及重构规则的方法.在此基础上,给出了根据形式化重构规则执行模型重构的具体步骤和策略,并提供了较为完整的模型重构CASE支撑工具.通过实例讨论了该模型重构描述语言的描述能力.结果表明,该语言具有较强的描述能力,能够比较简洁地描述复杂的模型重构规则.;This paper proposes a graph transformation based description language of model refactoring (GraTDeLMoR) to formalize model refactorings. It designs basic elements of the language according to the features of model refactorings, and proposes approaches to describe model refactorings with these basic elements. It also proposes steps of the application of refactorings formalized with the proposed language, and provides corresponding CASE support. The paper discusses the descriptive ability of the description language with some typical examples, and results suggest that the proposed language is expressive in formalizing model refactorings.
