A new object, populated with default values.

Implemented in Csla.DataPortal< T >.

CreateChild() [2/2]

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() [1/2]

Task< object > 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 >.

CreateChildAsync() [2/2]

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() [1/2]

object 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 >.

FetchChild() [2/2]

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() [1/2]

Task< object > 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 >.

FetchChildAsync() [2/2]

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() [1/2]

void Csla.IChildDataPortal< T >.UpdateChild	(	object	obj,
		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

obj	A reference to the business object to be updated.
parameters

Returns

A reference to the updated business object.

Implemented in Csla.DataPortal< T >.

UpdateChild() [2/2]

void Csla.IChildDataPortal< T >.UpdateChild	(	T	obj,
		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

obj	A reference to the business object to be updated.
parameters

Returns

A reference to the updated business object.

Implemented in Csla.DataPortal< T >.

UpdateChildAsync() [1/2]

Task Csla.IChildDataPortal< T >.UpdateChildAsync	(	object	obj,

	)

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

Parameters

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

UpdateChildAsync() [2/2]

Task Csla.IChildDataPortal< T >.UpdateChildAsync	(	T	obj,

	)

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

Parameters

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

Implemented in Csla.DataPortal< T >.
