摘要
1.引言面向对象是一种程序设计方法学,面向对象的程序设计风范受到了国内外计算机专家的密切关注,各种面向对象的语言也应运而生。为了探讨面向对象的并发理论,对面向对象的基础理论进行研究势在必行,本文介绍的演员系统(Actor System)就是作为面向对象的基本模型而提出来的。我们的目标是建立一种并发模型,它将在并发结构中起到图灵机在冯·诺依曼体系结构中所起的作用。下面,先回顾一下各种计算模型,比较它们可作为通用并发计算模型的可能性。
We give a description of the basic model, Actor Model, for concurrent object-oriented paradigm, By comparing it with other models of concurrency such as CSP, FP, GHCL etc., we make a discussion of this model in the following aspects: concurrent laws, semautic systems and characteristies of Actor languages, i. e., history-sensitive behavior, joint continuation, delayed evaluation and inherent concurrency. In the last part of the paper, we discuss the reason, why Actor system can be regarded as the thcorctical model for multicomputer system.
