VectorApparentDisplacementGetLightTravelTimeEvaluator Method (EvaluatorGroup)

Gets an evaluator that evaluates the light travel time between the two points involved in this displacement vector. If the input JulianDate to the evaluator represents the moment of an event at the InitialPoint, the returned Duration is the time until the event will be observed at the FinalPoint.

Namespace:  AGI.Foundation.Geometry
Assembly:  AGI.Foundation.Core (in AGI.Foundation.Core.dll) Version: 24.1.418.0 (24.1.418.0)

	EvaluatorGroup group


Type: AGI.FoundationEvaluatorGroup
The group with which to associate the new evaluator. By grouping evaluators that are often evaluated at the same Julian dates, common computations can be performed only once for the entire group instead of multiple times for each evaluator.

Return Value

Type: LinkDelayEvaluator
The evaluator.
If the Direction of this vector is Transmit, the returned duration will always be positive or zero. If the Direction of this vector is Receive, the returned duration will always be negative or zero. The JulianDate at which the event is observed at the FinalPoint can be obtained by adding the Duration returned by the evaluator to original JulianDate passed to the Evaluate method.
