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 Details

init
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 derivativefinalTime
 target time for the integration

handleStep
Handle the last accepted step. Parameters:
interpolator
 interpolator for the last accepted step

finish
Finalize integration. Parameters:
finalState
 state at integration end Since:
 2.0
