Parameters

start

Type: AGI.Foundation.TimeJulianDate
The start of the interval over which to evaluate.

stop

Type: AGI.Foundation.TimeJulianDate
The end of the interval over which to evaluate.

step

Type: AGI.Foundation.TimeDuration
The step size with which to sample this evaluator.

order

Type: SystemInt32
The target order to evaluate. Passing 0 evaluates the value only. Passing 1 evaluates the value and its derivative, etc. If necessary a result of lower or even higher order than the target may be returned.

tracker

Type: AGI.FoundationITrackCalculationProgress
The object to which progress is reported and that is able to cancel this operation before it is complete, or .

Return Value

This method takes advantage of the ThreadingPolicy to improve performance.

The first date in the returned collection will be start. The last date in the collection will be stop, so the difference between the second-to-last date and the last date may be less than step. Also, these dates will always be present in the returned collection even if the duration between them is less than step.
