public class FieldIntegratedEphemeris<T extends CalculusFieldElement<T>> extends FieldAbstractAnalyticalPropagator<T> implements FieldBoundedPropagator<T>
Instances of this class are built automatically when the getEphemerisGenerator method has been called. They are created when propagation is over.
Random access to any intermediate state of the orbit throughout the propagation range is
possible afterwards through this object.
A typical use case is for numerically integrated orbits, which can be used by algorithms that need to wander around according to their own algorithm without cumbersome tight links with the integrator.
As this class implements the Propagator
interface, it can itself be used in batch mode to build another instance of the
same type. This is however not recommended since it would be a waste of resources.
Note that this class stores all intermediate states along with interpolation models, so it may be memory intensive.

This method is similar in spirit to the FieldAbstractAnalyticalPropagator.propagate(org.orekit.time.FieldAbsoluteDate<T>, org.orekit.time.FieldAbsoluteDate<T>) method,
except that it does not call any handler during
propagation, nor any discrete events, not additional states. It always
stop exactly at the specified date.

FieldAbstractPropagatorThe propagation frame is the definition frame of the initial state, so this method should be called after this state has been set, otherwise it may return null.
