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.

| Modifier and Type | Method and Description |
|---|---|
| public void | handleStep(FieldStepInterpolator<T>
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
interpolator, boolean 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).true if the step is the last one isLast)Handle the last accepted step |

|---|---|
| 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.
