CreateChild()

T Csla.IChildDataPortal< T >.CreateChild

(

params object??[]

criteria

)

Called by a factory method in a business class to create a new object, which is loaded with default values from the database.

Parameters

criteria

Object-specific criteria.

Returns

A new object, populated with default values.

Implemented in Csla.DataPortal< T >.

CreateChildAsync()

Task< T > Csla.IChildDataPortal< T >.CreateChildAsync

(

params object??[]

criteria

)

Starts an asynchronous data portal operation to create a business object.

Parameters

criteria

Criteria describing the object to create.

Implemented in Csla.DataPortal< T >.

FetchChild()

T Csla.IChildDataPortal< T >.FetchChild

(

params object??[]

criteria

)

Called by a factory method in a business class to retrieve an object, which is loaded with values from the database.

Parameters

criteria

Object-specific criteria.

Returns

An object populated with values from the database.

Implemented in Csla.DataPortal< T >.

FetchChildAsync()

Task< T > Csla.IChildDataPortal< T >.FetchChildAsync

(

params object??[]

criteria

)

Starts an asynchronous data portal operation to create a business object.

Parameters

criteria

Criteria describing the object to create.

Implemented in Csla.DataPortal< T >.

UpdateChild()

void Csla.IChildDataPortal< T >.UpdateChild	(	T	child,
		params object??[]	parameters )

Called by the business object's Save() method to insert, update or delete an object in the database.

Note that this method returns a reference to the updated business object. If the server-side DataPortal is running remotely, this will be a new and different object from the original, and all object references MUST be updated to use this new object.

Parameters

child	A reference to the business object to be updated.
parameters	Optional arguments passed to child update methods.

Exceptions

ArgumentNullException

child is null.

Implemented in Csla.DataPortal< T >.

UpdateChildAsync()

Task Csla.IChildDataPortal< T >.UpdateChildAsync	(	T	child,
		params object??[]	parameters )

Called by a factory method in a business class or by the UI to update an object.

Parameters

child	Object to update.
parameters	Additional, optional parameters to pass.

Exceptions

ArgumentNullException

child is null.

Implemented in Csla.DataPortal< T >.
