      • canCompareEndpointsAsStrings

        public static boolean canCompareEndpointsAsStrings​(org.joda.time.Interval interval)
        Returns true if the provided interval has endpoints that can be compared against other DateTimes using their string representations. See also DateTimes.canCompareAsString(DateTime).

      • isEternity

        public static boolean isEternity​(org.joda.time.Interval interval)
        Returns true if the provided interval contains all time.

      • findOverlappingInterval

        @Nullable
public static org.joda.time.Interval findOverlappingInterval​(org.joda.time.Interval searchInterval,
                                                             org.joda.time.Interval[] sortedIntervals)
        Finds an interval from the given set of sortedIntervals which overlaps with the searchInterval. If multiple candidate intervals overlap with the searchInterval, the "smallest" interval based on the Comparators.intervalsByStartThenEnd() is returned.
        Parameters:
        searchInterval - Interval which should overlap with the result
        sortedIntervals - Candidate overlapping intervals, sorted in ascending order, using Comparators.intervalsByStartThenEnd().
        Returns:
        The first overlapping interval, if one exists, otherwise null.
