LinkDescriptor Class

Provides a description of modifications done to entities by operations returned in a DataServiceResponse.


Namespace:  System.Data.Services.Client
Assembly:  Microsoft.Data.Services.Client (in Microsoft.Data.Services.Client.dll)

public sealed class LinkDescriptor : Descriptor

The LinkDescriptor type exposes the following members.

Public propertySourceA source entity in a link returned by a DataServiceResponse.
Public propertySourcePropertyThe identifier property of the source entity in a link returned by a DataServiceResponse.
Public propertyStateWhen overridden in a derived class, gets the state of the object at the time this instance was constructed. (Inherited from Descriptor.)
Public propertyTargetThe source entity in a link returned by a DataServiceResponse.

Public methodEquals (Inherited from Object.)
Public methodGetHashCode (Inherited from Object.)
Public methodGetType (Inherited from Object.)
Public methodToString (Inherited from Object.)

The SaveChanges method returns a DataServiceResponse object that contains a series of OperationResponse objects, each of which contains a sequence of EntityDescriptor or LinkDescriptor instances that represent persisted changes.

For successful operations, the State property of the descriptor is set to unchanged and the new values for insert and update operations are merged according to the merge settings.

For operations with errors, the State of the descriptor will remain the same as they were before SaveChanges was called.

If an error occurred and processing stopped during an operation, the State will remain unchanged.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
