Detailed Description

Information necessary to synchronize entities across a group.

recompute() must be called after adding or modifying the instances of VariableSyncInfo.

Instances of this class are shared with all dispatchers (IVariableSynchronizeDispatcher) created from an instance of IVariableSynchronizer. Only the latter can therefore modify an instance of this class.
