Sync Framework Core Components

Microsoft Sync Framework core components can be used from an unmanaged language, such as C++, to perform synchronization. These components can be used to manage metadata and to create synchronization providers and applications. Conceptually, the core components can be grouped into the following categories: metadata services components, provider components, application components, and error codes.

Metadata Services Components

The following components help a provider process synchronization metadata:

ID_PARAMETER_PAIR Structure	IEnumSingleItemExceptions Interface
ID_PARAMETERS Structure	IEnumSyncChanges Interface
SYNC_GID Structure	IEnumSyncChangeUnits Interface
SYNC_ID Structure	IForgottenKnowledge Interface
SYNC_RANGE Structure	IKnowledgeBuilder Interface
SYNC_VERSION Structure	IRangeException Interface
SYNC_RESOLVE_ACTION Enumeration	IRecoverableError Interface
SYNC_CHANGE_FLAG Flags	IRecoverableErrorData Interface
IChangeConflict Interface	IReplicaKeyMap Interface
IChangeUnitException Interface	ISingleItemException Interface
IClockVector Interface	ISyncChange Interface
IClockVectorElement Interface	ISyncChangeBatch Interface
IClockVectorServices Interface	ISyncChangeBatchBase Interface
IDestinationChangeVersionsBuilder Interface	ISyncChangeBuilder Interface
IEnumChangeUnitExceptions Interface	ISyncChangeUnit Interface
IEnumClockVector Interface	ISyncFullEnumerationChangeBatch Interface
IEnumRangeExceptions Interface	ISyncKnowledge Interface

Provider Components

The following components enable a provider to interact with Sync Framework to perform synchronization on behalf of a replica:

SYNC_PROVIDER_ROLE Enumeration	IProviderFilteredSyncServices Interface
SYNC_SAVE_ACTION Enumeration	IProviderSyncServices Interface
SYNC_FILTER_INFO_FLAG Flags	ISaveChangeContext Interface
IAsynchronousDataRetriever Interface	ISaveChangeWithChangeUnitsContext Interface
IAsynchronousNotifyingChangeApplier Interface	ISyncFilterInfo Interface
IAsynchronousNotifyingChangeApplierTarget Interface	ISynchronousDataRetriever Interface
IAsynchronousNotifyingChangeApplierTargetCallback Interface	ISynchronousNotifyingChangeApplier Interface
IDataRetrieverCallback Interface	ISynchronousNotifyingChangeApplierTarget Interface
IKnowledgeSyncProvider Interface	ISyncProvider Interface
ILoadChangeContext Interface

Application Components

The following components enable an application to start a synchronization session and connect providers to perform synchronization:

SYNC_SESSION_STATISTICS Structure	IApplicationSyncServices Interface
CONFLICT_RESOLUTION_POLICY Enumeration	ISyncCallback Interface
SYNC_FULL_ENUMERATION_ACTION Enumeration	ISyncSession Interface
SYNC_PROGRESS_STAGE Enumeration	ISyncSessionState Interface

Error Codes

Sync Framework uses a set of custom errors to report problems. For more information, see Sync Framework Error Codes.
