Class FixedNumberInterpolationGrid

java.lang.Object
org.orekit.propagation.semianalytical.dsst.utilities.FixedNumberInterpolationGrid
All Implemented Interfaces:
InterpolationGrid
public class FixedNumberInterpolationGrid extends Object
Interpolation grid where a fixed number of points are evenly spaced between the start and the end of the integration step.

The grid is adapted to the step considered, meaning that for short steps, the grid will be dense, while for long steps the points will be far away one from each other

      Parameters:
      stepStart - start of the step
      stepEnd - end of the step
      Returns:
      time points between start and end

    • getGridPoints

      public <T extends CalculusFieldElement<T>> T[] getGridPoints(T stepStart, T stepEnd)
      Get grid points that are within the current step.

      The step is defined by its start and its end time.

      getGridPoints in interface InterpolationGrid
      Type Parameters:
      T - type of the elements
      Parameters:
      stepStart - start of the step
      stepEnd - end of the step
      Returns:
      time points between start and end

    • getPointsPerStep

      protected <T extends CalculusFieldElement<T>> int getPointsPerStep(T stepStart, T stepEnd)
