目前的面向对象框架存在规模大、使用复杂、文档含糊、不够准确等问题,给使用者带来一定的难度。针对上述问题,提出最大相同共享边子树的概念,将多个应用程序中的框架变化点实例化代码抽象成实例化关系树,基于最大相同共享边子树(MSET)给出可能的框架变化点实例化模式及相应的支持度。
It is very difficult to use OOF because the sizes of the frameworks are often large and many of the existing frameworks suffer from the lack of proper manuals and documentation.This paper proposes the concept of Maximum Sharing sub-Edge Tree(MSET).Based on MSET,it gives an algorithm for mining the framework hot-spot instantiation pattern.
