RecoverableErrorReportingContext Class
Represents the synchronization session context that is passed to the provider during some calls, so that the provider can report any recoverable errors that occur within the context of that call.
Assembly: Microsoft.Synchronization.SimpleProviders (in Microsoft.Synchronization.SimpleProviders.dll)
The RecoverableErrorReportingContext type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | Equals | (Inherited from Object.) |
![]() | Finalize | (Inherited from Object.) |
![]() | GetHashCode | (Inherited from Object.) |
![]() | GetType | (Inherited from Object.) |
![]() | MemberwiseClone | (Inherited from Object.) |
![]() | RecordConstraintError | Records a constraint error that occurred when attempting to apply a change to an item. Used to describe a local item that is in a constraint conflict with the change. |
![]() | RecordRecoverableErrorForChange | Records a recoverable error that occurred when attempting to apply a change to an item. |
![]() | ToString | (Inherited from Object.) |
The following code example shows an implementation of the InsertItem method that applies inserts to an in-memory sample data store. The method records a constraint error if the insert cannot be applied. To view this code in the context of a complete application, see the "Sync101 using Simple Sync Provider" application that is available in the Sync Framework SDK and from Code Gallery.
public override void InsertItem(object itemData, IEnumerable<SyncId> changeUnitsToCreate, RecoverableErrorReportingContext recoverableErrorReportingContext, out ItemFieldDictionary keyAndUpdatedVersion, out bool commitKnowledgeAfterThisItem) { ItemTransfer transfer = (ItemTransfer)itemData; ItemData dataCopy = new ItemData(transfer.ItemData); // Check for duplicates, and record a constraint error if a duplicate is detected. if (!_store.Contains(transfer.Id)) { _store.CreateItem(dataCopy, transfer.Id); keyAndUpdatedVersion = _store.CreateItemFieldDictionary(transfer.Id); } else { recoverableErrorReportingContext.RecordConstraintError(_store.CreateItemFieldDictionary(transfer.Id)); keyAndUpdatedVersion = null; } commitKnowledgeAfterThisItem = false; }
