Package org.orekit.propagation.sampling

Class FieldOrekitStepNormalizer<T extends CalculusFieldElement<T>>

java.lang.Object

org.orekit.propagation.sampling.FieldOrekitStepNormalizer<T>

Type Parameters:

T - type of the field elements

All Implemented Interfaces:

FieldOrekitStepHandler<T>

public class FieldOrekitStepNormalizer<T extends CalculusFieldElement<T>>
extends Object
implements FieldOrekitStepHandler<T>

This class wraps an object implementing OrekitFixedStepHandler into a OrekitStepHandler.

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

Constructor Detail

FieldOrekitStepNormalizer

public FieldOrekitStepNormalizer(T h,
                                 FieldOrekitFixedStepHandler<T> handler)

Simple constructor.

Parameters:

h - fixed time step (sign is not used)

handler - fixed time step handler to wrap

Method Detail

getFixedTimeStep

public T getFixedTimeStep()

Get the fixed time step.

Returns:

fixed time step

Since:

11.0

getFixedStepHandler

public FieldOrekitFixedStepHandler<T> getFixedStepHandler()

Get the underlying fixed step handler.

Returns:

underlying fixed step handler

Since:

11.0

requiresDenseOutput

public boolean requiresDenseOutput()

Determines whether this handler needs dense output. This handler needs dense output in order to provide data at regularly spaced steps regardless of the steps the propagator uses, so this method always returns true.

Returns:

always true

init

public void init(FieldSpacecraftState<T> s0,
                 FieldAbsoluteDate<T> 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 FieldOrekitStepHandler<T extends CalculusFieldElement<T>>

Parameters:

s0 - initial state

t - target time for the integration

handleStep

public void handleStep(FieldOrekitStepInterpolator<T> interpolator)

Handle the current step.

Specified by:

handleStep in interface FieldOrekitStepHandler<T extends CalculusFieldElement<T>>

Parameters:

interpolator - interpolator set up for the current step

finish

public void finish(FieldSpacecraftState<T> finalState)

Finalize propagation.

Specified by:

finish in interface FieldOrekitStepHandler<T extends CalculusFieldElement<T>>

Parameters:

finalState - state at propagation end
