public class DummyStepHandler extends Object implements StepHandler
This class is provided as a convenience for users who are only interested in the final state of an integration and not in the intermediate steps. Its handleStep method does nothing.
Since this class has no internal state, it is implemented using the Singleton design pattern. This means that only one instance is ever created, which can be retrieved using the getInstance method. This explains why there is no public constructor.
StepHandler| Modifier and Type | Method and Description |

static DummyStepHandler |
getInstance()
Get the only instance.

handleStep(StepInterpolator interpolator,
boolean isLast)
Handle the last accepted step.

init(double t0,
double[] y0,
double t)
Initialize step handler at the start of an ODE integration.

public void init(double t0, double[] y0, double t)
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.

handleStep in interface StepHandlerinterpolator - 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), it
should build a local copy using the clone method and store this
copy.isLast - true if the step is the last oneCopyright © 2003–2015 The Apache Software Foundation. All rights reserved.
