ISyncKnowledge interface (winsync.h)
Represents knowledge that a replica has about its item store.
Inheritance
The ISyncKnowledge interface inherits from the IUnknown interface. ISyncKnowledge also has these types of members:
Methods
The ISyncKnowledge interface has these methods.
| ISyncKnowledge::Clone Creates a new instance of this object, and copies the data from this object to the new object. |
| ISyncKnowledge::ContainsChange Indicates whether the specified item change is known by this knowledge. |
| ISyncKnowledge::ContainsChangeUnit Indicates whether the specified change unit change is known by this knowledge. |
| ISyncKnowledge::ContainsKnowledge Indicates whether the specified knowledge is known by this knowledge. |
| ISyncKnowledge::ConvertVersion Converts a version from another replica into one that is compatible with the replica that owns this knowledge. |
| ISyncKnowledge::ExcludeChangeUnit Removes knowledge about the specified change unit from the knowledge. |
| ISyncKnowledge::ExcludeItem Removes knowledge about the specified item from the knowledge. |
| ISyncKnowledge::FindClockVectorForChangeUnit Gets the clock vector that is associated with the specified change unit ID. |
| ISyncKnowledge::FindClockVectorForItem Gets the clock vector that is associated with the specified item ID. |
| ISyncKnowledge::FindMinTickCountForReplica Finds the minimum tick count in the knowledge for the specified replica. |
| ISyncKnowledge::GetChangeUnitExceptions Gets an object that can enumerate the IChangeUnitException objects that are stored in the knowledge. |
| ISyncKnowledge::GetOwnerReplicaId Gets the ID of the replica that owns this knowledge. |
| ISyncKnowledge::GetRangeExceptions Gets an object that can enumerate the IRangeException objects that are stored in the knowledge. |
| ISyncKnowledge::GetReplicaKeyMap Gets the IReplicaKeyMap object that is associated with this knowledge. |
| ISyncKnowledge::GetScopeVector Gets the clock vector that defines the changes that are contained in the knowledge. |
| ISyncKnowledge::GetSingleItemExceptions Gets an object that can enumerate the ISingleItemException objects that are stored in the knowledge. |
| ISyncKnowledge::GetVersion Gets the version of this knowledge structure. |
| ISyncKnowledge::MapRemoteToLocal Converts a knowledge object from another replica into one that is compatible with the replica that owns this knowledge. |
| ISyncKnowledge::ProjectOntoChangeUnit Gets the knowledge for the specified change unit. |
| ISyncKnowledge::ProjectOntoItem Gets the knowledge for the specified item. |
| ISyncKnowledge::ProjectOntoRange Gets the knowledge for the specified range of item IDs. |
| ISyncKnowledge::Serialize Serializes the knowledge object data to a byte array. |
| ISyncKnowledge::SetLocalTickCount Sets the tick count for the replica that owns this knowledge. |
| ISyncKnowledge::Union Combines the specified knowledge with the current knowledge. |
Remarks
Be aware that there is no single representation of knowledge. Equivalent knowledge might be represented in different forms and return different values from knowledge inspection methods, such as GetScopeVector, GetRangeExceptions, GetSingleItemExceptions, GetChangeUnitExceptions.
