Class AnalyticalEphemerisModeHandler

java.lang.Object

fr.cnes.sirius.patrius.propagation.analytical.AnalyticalEphemerisModeHandler

All Implemented Interfaces:

PatriusStepHandler, Serializable

public class AnalyticalEphemerisModeHandler
extends Object
implements PatriusStepHandler

This class stores sequentially generated orbital parameters for later retrieval.

Instances of this class are built and then must be fed with the results provided by Propagator objects configured in ephemeris generation mode. Once propagation is over, a BoundedPropagator can be built from the stored steps.

Constructor Detail

AnalyticalEphemerisModeHandler

public AnalyticalEphemerisModeHandler(Propagator propagatorIn,
                              AttitudeProvider attForcesProvider,
                              AttitudeProvider attEventsProvider)

Constructor.

Parameters:

propagatorIn - propagator

attForcesProvider - attitude provider for force computation

attEventsProvider - attitude provider for events computation

Method Detail

getEphemeris

public BoundedPropagator getEphemeris()

Get the generated ephemeris.

Returns:

a new instance of the generated ephemeris

setAttitudeProviderForces

public void setAttitudeProviderForces(AttitudeProvider attProvForces)

Set attitude provider for forces computation.

Parameters:

attProvForces - the attitude provider

setAttitudeProviderEvents

public void setAttitudeProviderEvents(AttitudeProvider attProvEvents)

Set attitude provider for events computation.

Parameters:

attProvEvents - the attitude provider

handleStep

public void handleStep(PatriusStepInterpolator interpolator,
              boolean isLast)
                throws PropagationException

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

init

public void init(SpacecraftState s0,
        AbsoluteDate t)

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
