摘要
传统的分布式对象技术不直接支持用户将数据从一个源传播到多个目的地,而传统的公布-订购技术不能够实现远程方法调用,这两种编程抽象结合起来就产生了有状态分布式对象(Stateful Distributed Object,SDO)技术。本方介绍了SDO的概念,并研究了SDO的关键实现技术,包括SDO公布状态的实现、服务者和代理的创建,以及公布状态的更新。
Traditional Distributed Object technology dose not support data propagation from one source to multiple destinations directly.Also,traditional Publish and Subscribe technology does not realize remote method invocation.The two technologies above combined into a new technology,say,Stateful Distributed Object（SDO）.This paper introduces the concept of SDO,then studies and illustrates the key points of SDO implementation by an example,including SDO publication state,servant and proxy creation,and publication state updating.
