| 摘要: |
| 该文给出了一种对C++进行并发扩充的方案.它基于这样的并发面向对象模型：系统由一组自治的并发对象构成,对象可以有一个体,一旦对象被创建,对象体就开始执行；对象间采用同步消息传递,允许对象内部的并发；对象的并发控制分散在各方法的激励条件中.文章还给出了一种转换策略,把扩充的C++描述转换成C++描述,使之能被现有的C++编译器识别.转换中利用了某些多任务操作系统(如Windows 95)所提供的多线程和同步设施. |

| An Approach to Concurrent Extension of C++ |

| Abstract: |
| In this paper, a concurrent object-oriented programming model is presented. It consists of a group of concurrent objects which may have bodies. When the concurrent object with a body is created, its body begin to run. In this model, the synchronous message passing is adopted for inter-object communication and the intra-object concurrency is permitted. The object concurrency control is distributed among each method's activation condition in an object. Based on the presented model, C++ is extended. A policy is also given to transform the classes defined in the extended C++ into C++ classes. The implementation uses the multithreading and synchronization mechanisms supported in some multitasking operating systems, such as Windows 95. |
| Key words: Object-oriented, concurrency, C++, concurrent extension, transformation. |
