FieldODEStepHandler (Hipparchus 3.0 API)

Type Parameters:

T - the type of the field elements

All Known Implementing Classes:

FieldDenseOutputModel, FieldStepNormalizer
```
public interface FieldODEStepHandler<T extends CalculusFieldElement<T>>
```
This interface represents a handler that should be called after each successful step.
The ODE integrators compute the evolution of the state vector at some grid points that depend on their own internal algorithm. Once they have found a new grid point (possibly after having computed several evaluation of the derivative at intermediate points), they provide it to objects implementing this interface. These objects typically either ignore the intermediate steps and wait for the last one, store the points in an ephemeris, or forward them to specialized processing or output methods.

- Method Detail
  - init
```
default void init(FieldODEStateAndDerivative<T> initialState,
                  T finalTime)
```
    Initialize step handler at the start of an ODE integration.
    This method is called once at the start of the integration. It may be used by the step handler to initialize some internal data if needed.
    
    The default implementation does nothing.
    
    Parameters:
    
    initialState - initial time, state vector and derivative
    
    finalTime - target time for the integration
  - handleStep
```
void handleStep(FieldODEStateInterpolator<T> interpolator)
```
    Handle the last accepted step.
    
    Parameters:
    
    interpolator - interpolator for the last accepted step
  - finish
```
default void finish(FieldODEStateAndDerivative<T> finalState)
```
    Finalize integration.
    
    Parameters:
    
    finalState - state at integration end
