如何保持共享对象的一致性是实时协同设计中的核心问题。文中介绍了一种新颖的保持共享对象一致性的方法。根据协同图形编辑系统中操作冲突的特点,使用消息驱动机制,配合同步机制和冲突检测与消解机制,使得系统既能保持共享对象的一致性,又满足了实时协同设计中的响应性、因果顺序一致性,并最大限度地保持了用户的操作目的。
How to maintain consistency of shared object is the kernel problem in real - time collaborative design. Introduces a novel method on consistency maintenance of shared object. Based on characteristic of operation conflict in collaborative graphics editing systems,employing the mechanism of message driving,with synchronization mechanism, collision detection and resolve mechanism,making system satisfy with consistency of shared object,responsiveness and eausal ordering, consistency of operation intention in collaborative design.
