  • Partition-based undo of partitioned object graph
    Patent number: 7567257
    Abstract: The performing of actions on an object graph that contains multiple objects. The objects are categorized into partitions. Taking into account the partitions, a particular non-final action performed on the object graph may be undone without necessarily first undoing all of the one or more subsequent actions. Instead, if the subsequent actions involved objects of different partitions than the objects that were affected by the particular action desired to be undone, the particular action may be undone without undoing the subsequent actions.
