      • handleStep

        public void handleStep​(FieldStepInterpolator<T> interpolator,
                               boolean isLast)
                        throws MaxCountExceededException
        Handle the last accepted step
        Specified by:
        handleStep in interface FieldStepHandler<T extends RealFieldElement<T>>
        Parameters:
        interpolator - interpolator for the last accepted step. For efficiency purposes, the various integrators reuse the same object on each call, so if the instance wants to keep it across all calls (for example to provide at the end of the integration a continuous model valid throughout the integration range, as the ContinuousOutputModel class does), it should build a local copy using the clone method of the interpolator and store this copy. Keeping only a reference to the interpolator and reusing it will result in unpredictable behavior (potentially crashing the application).
        isLast - true if the step is the last one
        Throws:
        MaxCountExceededException - if the interpolator throws one because the number of functions evaluations is exceeded
      • init

        public 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.

        Specified by:
        init in interface FieldStepHandler<T extends RealFieldElement<T>>
        Parameters:
        initialState - initial time, state vector and derivative
        finalTime - target time for the integration
