DataMappedObjectConverter.ConvertToUnderlyingRestriction Method (String, Int32, array<Object[], array<Object )

Converts the specified mapped restrictions into underlying restrictions that are data source specific.

Namespace:  Microsoft.VisualStudio.Data.Framework
Assembly:  Microsoft.VisualStudio.Data.Framework (in Microsoft.VisualStudio.Data.Framework.dll)

protected function ConvertToUnderlyingRestriction(
    mappedTypeName : String, 
    substitutionValueIndex : int, 
    mappedRestrictions : Object[], 
    parameters : Object[]
) : Object

Parameters

• mappedTypeName
  Type: System.String

  The name of the mapped type.

• substitutionValueIndex
  Type: System.Int32

  Index into the array of substitution values.

• mappedRestrictions
  Type: array<System.Object[]

  An array containing the mapped restrictions.

• parameters
  Type: array<System.Object[]

  An array containing the parameters.

Return Value

Type: System.Object
The underlying restriction that is converted from the mapped restriction.

Remarks

This method is useful when the mapped object selector ([T:Microsoft.VisualStudio.Data.Services.IVsDataMappedObjectSelector)] needs to convert the mapped restrictions to the underlying restrictions to pass to the data source–specific type selector (IVsDataMappedObjectSelector.) This process is referred to as mapped selection.

Notes to Inheritors

The derived class should override this method. The base implementation of this method throws a NotImplementedException.
