Member Function Documentation

Create()

async Task< DataPortalResult > Csla.Server.TransactionalDataPortal.Create ( [DynamicallyAccessedMembers(DynamicallyAccessedMemberTypes.PublicConstructors)] Type objectType, object criteria, DataPortalContext context, bool isSync )

inline

Wraps a Create call in a TransactionScope.

This method delegates to SimpleDataPortal but wraps that call within a TransactionScope to provide transactional support via System.Transactions.

Parameters

objectType	A System.Type object indicating the type of business object to be created.
criteria	A custom criteria object providing any extra information that may be required to properly create the object.
context	Context data from the client.
isSync	True if the client-side proxy should synchronously invoke the server.

Returns

A populated business object.

Exceptions

ArgumentNullException

objectType , criteria or context is null.

Implements Csla.Server.IDataPortalServer.

Delete()

async Task< DataPortalResult > Csla.Server.TransactionalDataPortal.Delete ( [DynamicallyAccessedMembers(DynamicallyAccessedMemberTypes.PublicConstructors)] Type objectType, object criteria, DataPortalContext context, bool isSync )

inline

Called by the client-side DataPortal to delete an object.

This method delegates to SimpleDataPortal but wraps that call within a TransactionScope to provide transactional support via System.Transactions.

Parameters

objectType	Type of business object to create.
criteria	Object-specific criteria.
context	Context data from the client.
isSync	True if the client-side proxy should synchronously invoke the server.

Exceptions

ArgumentNullException

objectType , criteria or context is null.

Implements Csla.Server.IDataPortalServer.

Fetch()

async Task< DataPortalResult > Csla.Server.TransactionalDataPortal.Fetch ( [DynamicallyAccessedMembers(DynamicallyAccessedMemberTypes.PublicConstructors)] Type objectType, object criteria, DataPortalContext context, bool isSync )

inline

Called by the client-side DataPortal to retrieve an object.

This method delegates to SimpleDataPortal but wraps that call within a TransactionScope to provide transactional support via System.Transactions.

Parameters

objectType	Type of business object to retrieve.
criteria	Object-specific criteria.
context	Object containing context data from client.
isSync	True if the client-side proxy should synchronously invoke the server.

Returns

A populated business object.

Exceptions

ArgumentNullException

objectType , criteria or context is null.

Implements Csla.Server.IDataPortalServer.

Update()

async Task< DataPortalResult > Csla.Server.TransactionalDataPortal.Update ( ICslaObject obj, DataPortalContext context, bool isSync )

inline

Called by the client-side DataPortal to update an object.

This method delegates to SimpleDataPortal but wraps that call within a TransactionScope to provide transactional support via System.Transactions.

Parameters

obj	A reference to the object being updated.
context	Context data from the client.
isSync	True if the client-side proxy should synchronously invoke the server.

Returns

A reference to the newly updated object.

Exceptions
