FieldOrekitFixedStepHandler (ORbit Extrapolation KIT 9.3 API)

```
public interface FieldOrekitFixedStepHandler<T extends org.hipparchus.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

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	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)
```
    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.
  - handleStep
```
void handleStep(FieldSpacecraftState<T> currentState,
                boolean isLast)
```
    Handle the current step.
    
    Parameters:
    
    currentState - current state at step time
    
    isLast - if true, this is the last integration step
