主动对象 meaning in English
active object
Examples
- This element which is base on uml extension mechanism is a complementary of uml standard semantic
其中，封装体代表系统中并行运行的基本单位，因此是一种特殊的主动对象。 - Firstly , we define the uml semantic of this model element based on uml extension mechanism , including capsule that is a kind of active class to represent the concurrent unit and protocol derived from collaboration , which mainly is used to describe the communication between capsules
它有着区别于主动对象的语义和表示方法，而协议被定义为一种协作，端口是参与协作的主要角色，通过状态机定义了端口间消息收发的序列，并隐式地描述了封装体对象之间的同步要求。 - It demonstrates the feasibility of incorporating orb with mom , designs and implements rtps , a orb - based mom , which focuses on decentralized real - time publish - subscribe , removes the bottleneck by simplifing the responsibility of one node , and adopts the collocated client / server to set up a peer - to - peer ( p2p ) communication style . 2 . it points out the importance of asynchronous concurrent processing to dynamic responsive system , carries out a in - depth research on object - oriented multi - threaded architecture , designs and implements rtps _ thread _ manager , studies the active object pattern in detail and implements its core , that is rtpstask , as well as gives its varieties
论文主要的技术贡献有：论证了orb与mom两种技术相结合构建实时消息中间件rtps的可行性；设计实现rtps的体系结构：该结构以分布式实时发布-订阅为核心，通过职责精简消除了系统瓶颈，采用客户服务器并置( collocation )实现了对等模式通信；指出异步并发处理对于动态响应系统的重要性，深入研究了用以提高发布-订阅并发程度的面向对象多线程架构、设计实现了对象化线程管理器rtps thread manager ，详细论述了将对象的方法执行与方法调用分离在不同线程内的设计模式，即主动对象( activeobiect )的原理及核心实现rtps task ，并结合rtps设计实现指出了主动对象的几个变种。 - As the standard modeling language , uml is the most important achievement in the object - oriented technique . during the developing of system based on uml , developers used to using active object to represent the concurrent entity . because the shortage of the describing capability , active object often fail to describe the system concurrency explicitly
Uml作为面向对象的标准建模语言，是面向对象技术领域中的重要成果，在采用uml进行实时系统开发的过程中，人们往往采用主动对象来表示系统中并行运行的实体，而主动对象由于表达能力的限制，不能够对系统的并发性作出一个完整的、详尽的描述，这就要求我们能够提供一种新的机制来描述实时系统中的并行对象。
