  org.orekit.attitudes.AttitudeChronologicalComparator

All Implemented Interfaces:

Serializable, Comparator<Attitude>

public final class AttitudeChronologicalComparator
extends Object
implements Comparator<Attitude>, Serializable

This class is a comparator used to compare the Attitude objects in the ephemeris set. This comparators allows two identical attitudes ephemeris to be kept in the set; this feature is important to compute two ephemeris at the attitude transition points.

Parameters:

o1 - first Attitude instance

o2 - second Attitude instance
