| 摘要: |
| 干涉问题是指基础程序和方面之间或者方面之间发生不需要的相互作用,导致最终程序中产生不想要的功能,危害程序的正确性.很难检测和修正在面向方面设计中存在的干涉,已经成为推广面向方面技术的阻碍.受到技术自身可扩展能力的局限,现有的基于模型验证技术的工作不能有效地处理功能干涉问题.设计开发了基于推理验证技术直接检查和去除面向方面设计中功能干涉的工具,它可以根据类和方面的功能规约自动产生确保不发生干涉的条件,并引入交互式证明工具PVS来提高证明过程的自动化程度.证明可以确认设计中无干涉存在或者为修正干涉问题提供线索. |

| Abstract: |
| Interference problems refer to the undesired interaction between aspects and base programs or interaction between aspects that results in unexpected functions and is harmful to the correctness of the entire program.The difficulty in detecting and fixing interferences in aspect-oriented designs impedes the widespread application of aspect-oriented programming paradigm.Suffered from the scalability problem, existing researches that use model checking techniques cannot effectively handle functional interferences.The paper designs and implements a tool that employs deduction-based technologies to support direct checking and remove functional interferences in aspect-oriented designs.This tool can automatically generate proof obligations excluding the existence of interference.In addition, the paper introduces the tool PVS to raise the automation level of verification.The proof can either ascertain no interference exists or give clues on how to rectify the design. |
