public interface StepInterpolatorWithJacobians
extends java.io.Externalizable
The various ODE integrators provide objects implementing this interface to the step handlers. These objects are often custom objects tightly bound to the integrator internal algorithms. The handlers can use these objects to retrieve the state vector at intermediate times between the previous and the current grid points (this feature is often called dense output).
One important thing to note is that the step handlers may be so
tightly bound to the integrators that they often share some internal
state arrays. This imply that one should never use a direct
reference to a step interpolator outside of the step handler, either
for future use or for use in another thread. If such a need arise, the
step interpolator must be copied using the dedicated
copy() method.

setInterpolatedTime(double) has not been called, it returns
the current grid point time.void setInterpolatedTime(double time)
Setting the time outside of the current step is now allowed, but should be used with care since the accuracy of the interpolator will probably be very poor far from this step. This allowance has been added to simplify implementation of search algorithms near the step endpoints.
Setting the time changes the instance internal state. If a
specific state must be preserved, a copy of the instance must be
created using copy().

This method provides the integration direction as specified by the integrator itself, it avoid some nasty problems in degenerated cases like null steps due to cancellation at step initialization, step control or discrete events triggering.
StepInterpolatorWithJacobians copy() throws DerivativeException
The copied instance is guaranteed to be independent from the original one. Both can be used with different settings for interpolated time without any side effect.
