Fetch Method (IDataFetch)

Fetches WebSchedule objects from the underlying data source.

Syntax

Visual Basic

'Declaration
 
Sub Fetch( _
   ByVal context As DataContext _
) 

C#

void Fetch( 
   DataContext context
)

Parameters

context

A DataContext subclass containing parameter values for use when carrying out a fetch operation.

Remarks

The implementation of Fetch will ordinarily examine the OperationName of the supplied context (parameters for the select or retrieval operation), and dispatch it to another method specifically designed for performing the requested operation.

In addition to naming the operation, the supplied DataContext will also encapsulate all of the information necessary to perform the operation. Examples of this sort of information would include key values, range boundaries, or any other material that would serve as criterion for the selection of information to return from the data source.

The included WebSchedule data providers already implement IDataFetch, so most developers do not need to contemplate implementing this interface unless they want to extend the functionality of the WebSchedule data model with their own custom data provider.
