Gets an evaluator that can be used to find the Motion<Cartesian> of this vector at a given date with respect to the axes in which it is defined. See GetEvaluator(EvaluatorGroup) for details.(Inherited from Vector.)
This type will usually not be used directly, it is instead used by PropagationVector behind the scenes. If this type is used, such as during the implementation of a type similar to or deriving from PropagationVector, always call ConfigureIndicesOnEvaluator(EvaluatorGroup, VectorPropagationParameter, MotionInt32) prior to this method.
