Class MultiPatriusStepNormalizer

java.lang.Object

fr.cnes.sirius.patrius.propagation.sampling.multi.MultiPatriusStepNormalizer

All Implemented Interfaces:

MultiPatriusStepHandler

public class MultiPatriusStepNormalizer
extends Object
implements MultiPatriusStepHandler

This class is copied from PatriusStepNormalizer and adapted to multi propagation.

This class wraps an object implementing MultiPatriusFixedStepHandler into a MultiPatriusStepHandler.

It mirrors the StepNormalizer interface from commons-math but provides a space-dynamics interface to the methods.

Modified to take into account propagation direction (in time). Lines 111 to 115 Cf A-1031.

Since:

3.0

Constructor Detail

MultiPatriusStepNormalizer

public MultiPatriusStepNormalizer(double hIn,
                                  MultiPatriusFixedStepHandler handlerIn)

Simple constructor.

Parameters:

hIn - fixed time step (sign is not used)

handlerIn - fixed time step handler to wrap

Method Detail

init

public void init(Map<String,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 MultiPatriusStepHandler

Parameters:

s0 - map of initial states

t - target time for the integration

handleStep

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

Handle the last accepted step.

Specified by:

handleStep in interface MultiPatriusStepHandler

Parameters:

interpolator - interpolator for the last accepted step. For efficiency purposes, the various propagators reuse the same object on each call, so if the instance wants to keep it across all calls (for example to provide at the end of the propagation a continuous model valid throughout the propagation range), it should build a local copy using the clone method and store this copy.

isLast - true if the step is the last one

Throws:

PropagationException - this exception is propagated to the caller if the underlying user function triggers one
