摘要
加锁是分布式协同编辑系统中防止并行操作中出现冲突的一种重要手段。本文针对基于GIS组件的雷达兵作战计划协同制定系统的特殊要求提出一种加锁机制,用户可以将图层锁、对象类型锁、区域锁和对象锁交叉使用。这种锁机制是一种细粒度和粗粒度的结合,使用户间的协作更加灵活。
Locking is an important technique in distributed cooperative editing system used to prevent conflicting. In this paper, a novel hybrid scheme for lock is proposed for the special demand of radar troops cooperative battle plan editing systems based on COM GIS.User could across use layer lock,object type lock,region lock or object lock.Therefore,this is a combination of finegrain locking and coarse-grain locking, thus make the cooperation of users more neatly.
