Implementing a BulkIdEnumerator
Applies to: SharePoint Server 2010
Description
A BulkIdEnumerator method instance returns minimal information about the external items corresponding to the given identities.
This method can be used to optimize synchronization of cached data. This method ideally returns only the identities and version information of the external items corresponding to given identities, which the calling application can compare with the local version to identify whether anything has changed, and if so, request the changed external items to update the cached data.
This method can potentially return many external items. Rich filtering can be specified to filter the results and optimize the behavior. For more information about how to use filters, see IFilterCollection.
This method returns an IEntityInstanceEnumerator.
