Abstract

Context-oriented programming languages allow programmers to develop context-aware systems that can adapt their behaviour dynamically upon changing contexts. Due to the highly dynamic nature of such systems and the many possible combinations of contexts to which such systems may adapt, developing such systems is hard. Feature-based context-oriented programming helps tackle part of this complexity by modelling the possible contexts, and the different behavioural adaptations they can trigger, as separate feature models. Tools can also help developers address the underlying complexity of this approach. This paper presents a visualisation tool that is intricately related to the underlying architecture of a feature-based context-oriented programming language, and the context and feature models it uses. The visualisation confronts two hierarchical models (a context model and a feature model) and highlights the dependencies between them. An initial user study of the visualisation tool is performed to assess its usefulness and usability.
面向上下文的程序员的特性和上下文的动态可视化
面向上下文的编程语言允许程序员开发上下文感知系统,这些系统可以根据上下文的变化动态地调整其行为。由于此类系统的高度动态性以及此类系统可能适应的许多可能的上下文组合,开发此类系统是困难的。基于特征的面向上下文的编程通过建模可能的上下文,以及它们可以触发的不同行为适应,作为单独的特征模型,帮助解决这种复杂性的一部分。工具还可以帮助开发人员解决这种方法的潜在复杂性。本文提出了一种可视化工具,它与基于特征的面向上下文的编程语言的底层架构及其使用的上下文和特征模型有着复杂的关系。可视化处理两个层次模型(上下文模型和特征模型),并突出显示它们之间的依赖关系。对可视化工具进行初步用户研究,以评估其有用性和可用性。
