EnumerateIdentities method

IEntity.EnumerateIdentities method

Enumerates identities.

Namespace:  Microsoft.BusinessData.MetadataModel
Assembly:  Microsoft.BusinessData (in Microsoft.BusinessData.dll)

IEntityInstanceEnumerator EnumerateIdentities(
	IFilterCollection filterCollection,
	ILobSystemInstance lobSystemInstance
)

Parameters

filterCollection
Type: Microsoft.BusinessData.Runtime.IFilterCollection

The filters to apply.

lobSystemInstance
Type: Microsoft.BusinessData.MetadataModel.ILobSystemInstance

The external system instance.

Return value

Type: Microsoft.BusinessData.Runtime.IEntityInstanceEnumerator
The enumerator to external items with minimal data.

This method can potentially return a lot of external items. IFilterCollection 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, which requires special clean up and may expose additional functionality to control the behavior when the external system returns data in batches. For more information about how to use external item enumerators, see IEntityInstanceEnumerator.

Instances of objects in the Business Data Connectivity object model are tied to the Metadata Store they are obtained from. Using instances tied to one Metadata Store with the instances from another Metadata Store will cause data corruption and other unexpected behavior. For more information, see DatabaseBackedMetadataCatalog, FileBackedMetadataCatalog, and RemoteSharedFileBackedMetadataCatalog.
