virtual MgCoordinateSystemGeodeticTransformDef* MgCoordinateSystemTransform::GetGeodeticTransformation ( INT32 index ) [pure virtual]

Returns a pointer to the catalog-resident(!) geodetic transformation definition indicated by the index parameter.

Parameters:

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

Returns:: Returns a disposable pointer to the geodetic transformation definition indicated by the index parameter. The MgCoordinateSystemGeodeticTransformDef instance is guaranteed to exist in the geodetic transformation definition dictionary.

Exceptions:

MgIndexOutOfRangeException	if index is out of range. See MgCoordinateSystemTransform::GetGeodeticTransformationCount.
MgCoordinateSystemLoadFailedException	if the geodetic transformation denoted by the index is not contained in the dictionries but has been created in-memory only. Note though, that this will only in very rare circumstances.
MgCoordinateSystemInitializationFailedException	if the the transformation definition object could not be setup.
MgException	if the dictionaries could not be accessed or any other error condition has been encountered.
