Compute the state and derivatives at the interpolated time. This is the main processing method that should be implemented by the derived classes to perform the interpolation.

Specified by:: computeInterpolatedStateAndDerivatives in class AbstractFieldODEStateInterpolator<T extends CalculusFieldElement<T>>
Parameters:: mapper - mapper for ODE equations primary and secondary components; time - interpolation time; theta - normalized interpolation abscissa within the step (theta is zero at the previous time step and one at the current time step); thetaH - time gap between the previous time and the interpolated time; oneMinusThetaH - time gap between the interpolated time and the current time
Returns:: interpolated state and derivatives
Throws:: MathIllegalStateException - if the number of functions evaluations is exceeded
