协同设计中保证意愿的Undo技术

Undo techniques of intention guarantee in collaborative design

分析了Undo操作意愿保证的特性和已有方案存在的问题 ,给出了一个保证Undo操作意愿 ,也满足与被Undo的操作相关联的其它操作的意愿的方案。针对单对象和多版本的特性 ,以及创建操作和一般操作类型 ,依据给出操作可互换性定义 ,提出了相关的解决策略和算法 。

The properties of intention guarantee of Undo operation and problems existed in the existing schemes were analyzed, an intention for guarantee the Undo operation was presented, which also satisfies the intention scheme of other operations being correlated to the Undo operation. Aimed at the properties of single object and multi-version, and establishing operation and ordinary types of operation, and in accordance with the given definition of operational interchangeability, the related solving strategy and algorithm were advanced and the verification was obtained in the prototype system.
