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 oneDerivativeException
- if user code called from step interpolator
finalization triggers onepublic boolean requiresDenseOutput()
This method allows the integrator to avoid performing extra
computation if the handler does not need dense output. If this
method returns false, the integrator will call the StepHandler.handleStep(org.apache.commons.math.ode.sampling.StepInterpolator, boolean)
method with a DummyStepInterpolator
rather
than a custom interpolator.
