public abstract class FieldAbstractAnalyticalPropagator<T extends org.hipparchus.RealFieldElement<T>> extends FieldAbstractPropagator<T>
FieldPropagator
methods for analytical propagators.
This abstract class allows to provide easily the full set of FieldPropagator
methods, including all propagation
modes support and discrete events support for any simple propagation method. Only
two methods must be implemented by derived classes: propagateOrbit(FieldAbsoluteDate)
and getMass(FieldAbsoluteDate)
. The first method should perform straightforward
propagation starting from some internally stored initial state up to the specified target date.

public FieldSpacecraftState<T> propagate(FieldAbsoluteDate<T> start, FieldAbsoluteDate<T> target)
Those propagators use a start date and a target date to compute the propagated state. For propagators using event detection mechanism, if the provided start date is different from the initial state date, a first, simple propagation is performed, without processing any event computation. Then complete propagation is performed from start date to target date.

This method is similar in spirit to the 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.
