摘要
研究构件动态更新的关键问题――新旧构件实例间的状态传递。根据类的不同改变方式,提出一种不修改虚拟机的对象动态替换方法,有效地控制改变蔓延,并设计了状态传递算法和实验系统,借助Java虚拟机的类装载机制和反射机制,实现了构件实例间的状态传递。
Focusing on state transfer between components in dynamic update, an approach that can dynamically update objects is proposed and the so-called modification spread without modifying JVM is prevented. On basis of the mechanism of JVM＇s class loading and reflection, an experimental system which implements state transfer is designed.
