随着因特网成为主流软件的运行环境,计算模式逐步进入开放、动态以及用户需求频繁变化的环境,导致软件系统需动态地调整软件的组织结构或者功能行为来满足外界变化的需求.基于设计模式中的命令模式,利用方法调用与方法执行分离的原则和采用集中调度控制所有方法执行的方式,设计出一种灵活的软件在线演化机制.通过实例验证,本机制能在运行时刻灵活方便地变更软件的功能行为和流程逻辑.

With the intemet being the main runtime environment.the computer model is increasingly under the more open,dynamic and variable environment.So the software must dynastically adjust the organization or behavior to satisfy the changing requirement.Based on the command pattern,utilizing the isolation of method invocation and method execution and using centralized schedule,we designed a flexible online evolution mechanism.Finally the mechanism was testified to be convenient for changing system function and logic flow.
