DataMappedObjectConverter.ConvertToUnderlyingRestriction Method (String, Int32, [], [])

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)

    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: []

An array containing the mapped restrictions.

parameters
Type: []

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.
