Create()

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

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 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.

Implements Csla.Server.IDataPortalServer.

Delete()

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

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.

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

Called by the client-side DataProtal 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.

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

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.
