Interface FieldOrekitFixedStepHandler<T extends RealFieldElement<T>>

public interface FieldOrekitFixedStepHandler<T extends RealFieldElement<T>>

This interface is a space-dynamics aware fixed size step handler.

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

Method Summary

Modifier and Type	Method and Description
void	handleStep(FieldSpacecraftState<T> currentState, boolean isLast) Handle the current step.
default void	init(FieldSpacecraftState<T> s0, FieldAbsoluteDate<T> t, T step) Initialize step handler at the start of a propagation.

Method Detail

init

default void init(FieldSpacecraftState<T> s0,
                  FieldAbsoluteDate<T> t,
                  T step)
           throws OrekitException

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.

Parameters:

s0 - initial state

t - target time for the integration

step - the duration in seconds of the fixed step. This value is positive even if propagation is backwards.

Throws:

OrekitException - if step handler cannot be initialized

handleStep

void handleStep(FieldSpacecraftState<T> currentState,
                boolean isLast)
         throws OrekitException

Handle the current step.

Parameters:

currentState - current state at step time

isLast - if true, this is the last integration step

Throws:

OrekitException - if step cannot be handled
