非标准设计模式的恢复

Recovery of non-standard design pattern

为解决非标准设计模式不易恢复的问题,提出一种非标准设计模式恢复方法,关注设计模式重叠与变体,描述设计模式实例重叠的情形。以Decorator为例总结3种典型的变体实现,通过手工的形式验证经典开源系统中State与Strategy模式重叠实例及Decorator与Composite模式变体的基准数及所处目录位置,以5种主流设计模式恢复工具进行非标准设计模式恢复实验,实验结果表明,矩阵积分评估的策略取得了较好的效果,非标准设计模式恢复值得深入研究。

To solve difficulty recovery of non-standard design pattern,a recovery method for non-standard design pattern was proposed.Focusing on overlap and variant of design pattern,design pattern instance overlap was described.Decorator pattern was taken as an example,focusing on three variants of the bridge pattern.Benchmark and catalog of non-standard design pattern based on overlapping pattern instances of State/Strategy and variant instances of Decorator/Composite in open source system were mined by manual.A nonstandard design pattern test was carried out by five design pattern detection tools based on open source systems.Experimental results show that the method based on the matrix grade evaluation achieves good results,indicating the necessity of non-standard design pattern recovery studies.
