DC＋＋：一种面向对象的分布式程序设计语言

DC++:A Kind of Object-Oriented Distributed Programming Language

本文提出了一种新的面向对象的分布式程序设计语言ＤＣ＋＋（ｄｉｓｔｒｉｂｕｔｅｄＣ＋＋）．在ＤＣ＋＋语言中增加了一系列关于分布式程序设计的语言设施，以便于程序员灵活应用，编写出高质量的分布运行的程序．它以活动对象──进程作为分布单位，采用汇合机制实现进程间的同步和通信，并且支持进程的动态创建和撤消，同时提供了丰富的进程通信控制设施．进程组概念的引入，提供了一组进程中的各个成员与外部世界的统一接口，增强了对系统的控制，是ＤＣ＋＋语言的一大特色．

This paper discusses issues in the design and implementation of a language named DC++(distributed C++). The language is upward-compatible to C++,and its basic building block is process,a class with its own thread of control. DC++ supports both the synchronous and asynchronous communication models and provides the programmer with various facilities for process communication purposes. The group concept allows the programmer to consider a collection of processes as a unique entity,and provides an interface between them and the outside world.
