实现异步调用的扩展模型

The Implementation of the Asynchronous Call Extended Model

分布计算技术和面向对象技术相结合而形成的分布对象技术已经发展成为当今分布异构环境下建立应用系统集成框架和标准构件的核心技术。OMG组织制定的CORBA标准与Microsoft的COM/DCOM标准以及Sum公司的JavaRMI标准一起形成了分布对象技术领域的主流。本文针对现有的CORBA 2 .0规范在静态调用时不支持异步操作的情况 ,提出了一种静态调用扩展模型 ,使得在静态调用时能支持异步操作。

The distributed object oriented technique resulted from the combination of the distributed calculating technique and the object oriented technique has evolved as the core technique for establishing the integrating framework and standard components in the isomeric environment.The OMG CORBA,in conjunction with the Microsoft COM/DCOM and the Sun Jave RMI,leads the distributed object oriented technique.As the CPRBA V2.0 does not support the asynchronous operations in the static call,this paper provides an extended static call model.The implementation of the extended model is described in detail.
