TEFL:一种文本式特征建模语言

TEFL:A Textual Feature Modeling Language

特征模型已经成为软件产品线工程中共性/可变性建模的事实标准.现有基于特征图的建模工具由于在模型表达能力、严谨的形式化语义等方面的不足限制了其在工业界的应用.为了消除这些建模中的缺陷,为基于特征的产品线开发提供一个坚实的支撑环境,提出文本式特征建模语言TEFL,介绍其具体语法、抽象语法,以及形式化语义;开发一个基于Eclipse的语言编辑器原型;给出了面向XML和Java语言应用转化方法和工具;分析了与现有文本式建模技术相比所具有的优势与不足,并指出在特征建模及其工具技术方面的进一步的工作方向.

Feature models are the de-facto standard for modeling commonality and variability in software product line engineering.Existing diagram-based feature modeling tools suffer from a lack of adoption in the industry due to their lack of conciseness and expressiveness.To overcome these shortcomings and provide a solid supporting environment for feature-based product lines development,this paper proposes a textual feature modeling language,called TEFL,with its concrete syntax,Abstract syntax,and formal semantics.We develop an Eclipse-based editor prototype for it,and show its usage with transformation methods and tools in the scenarios of XML community and Java language environment.We also discuss the advantages and shortcomings of TEFL compared to existing textual modeling techniques and point out further directions in feature modeling and related tool technologies.
