- All Implemented Interfaces:
public final class DummyStepHandler extends Object implements StepHandlerThis class is a step handler that does nothing.
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.

init(double t0, double y0, double t)Initialize step handler at the start of an ODE integration.
public static DummyStepHandler getInstance()Get the only instance.
- the only instance
public void init(double t0, double y0, double t)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.
public void handleStep(StepInterpolator interpolator, boolean isLast)Handle the last accepted step. This method does nothing in this class.
- Specified by:
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), it should build a local copy using the clone method and store this copy.
isLast- true if the step is the last one
