virtual INT32 MgCoordinateSystemTransform::GetGeodeticTransformationDirection

(

INT32

index

)

[pure virtual]

Returns the direction of the transformation definition indicated by the index parameter.

Parameters:

index

A zero based index indicating the specific transformation definition for which the direction is to be returned.

Returns:

Returns a memebr of the MgCoordinateSystemGeodeticDirection class:

• MgCoordinateSystemGeodeticDirection::GeodeticDirectionForward for the forward direction,
• MgCoordinateSystemGeodeticDirection::GeodeticDirectionInverse or the inverse direction,
• MgCoordinateSystemGeodeticDirection::GeodeticDirectionNone if there is no specification (e.g. a null transformation), and
• MgCoordinateSystemGeodeticDirection::GeodeticDirectionError if the index parameter is invalid.

Remarks:

No exceptions are thrown.
