public ForcesStepHandler(OrbitNatureConverter converterIn,
                         NonInertialContribution nonInertialContributionIn)

Constructor.

Parameters:

converterIn - orbit nature converter

nonInertialContributionIn - nonInertialContribution force (null if not used)

Method Detail

init

public void init(SpacecraftState s0,
                 AbsoluteDate t)

Description copied from interface: PatriusStepHandler

Initialize step handler at the start of a propagation.

This method is called once at the start of the propagation. It may be used by the step handler to initialize some internal data if needed.

Specified by:

init in interface PatriusStepHandler

Parameters:

s0 - initial state

t - target time for the integration

handleStep

                       boolean isLast)
                throws PropagationException

Description copied from interface: PatriusStepHandler

Handle the current step.

Specified by:

handleStep in interface PatriusStepHandler

Parameters:

interpolator - interpolator set up for the current step

isLast - if true, this is the last integration step

Throws:

PropagationException - if step cannot be handled

getDnonInertial

public double[] getDnonInertial()

Getter for non-inertial contribution.

Returns:

non-inertial contribution
