Class MultiOrekitStepNormalizer

java.lang.Object
  fr.cnes.sirius.patrius.propagation.sampling.multi.MultiOrekitStepNormalizer

All Implemented Interfaces:

MultiOrekitStepHandler

public class MultiOrekitStepNormalizer
extends Object
implements MultiOrekitStepHandler

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

This class wraps an object implementing MultiOrekitFixedStepHandler into a MultiOrekitStepHandler.

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

MultiOrekitStepNormalizer

public MultiOrekitStepNormalizer(double hIn,
                                 MultiOrekitFixedStepHandler 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 MultiOrekitStepHandler

Parameters:

s0 - map of initial states

t - target time for the integration

handleStep

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

Handle the last accepted step.

Specified by:

handleStep in interface MultiOrekitStepHandler

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
