adjustRrule

public static void adjustRrule(net.fortuna.ical4j.model.property.RRule rRule,
 Date start,
 TimeZone tz)

Adjust the given UTC rrule to the given timezone.

Parameters:

rRule - The rrule to adjust.

start - The start date in UTC

tz - The target timezone.

calculatePeriods

public static List<net.fortuna.ical4j.model.Period> calculatePeriods(Date start,
 Date end,
 long duration,
 net.fortuna.ical4j.model.property.RRule rRule,
 TimeZone tz)

Backward compatibility, converts parameters as required for the updated calculatePeriods

Parameters:

start - date in the scheduled time zone

end - date in the scheduled time zone

duration -

rRule -

tz - , time zone of the scheduled event

Returns:

the calculated periods

calculatePeriods

public static List<net.fortuna.ical4j.model.Period> calculatePeriods(Calendar startCalTz,
 Calendar endCalTz,
 long duration,
 net.fortuna.ical4j.model.Recur recur,
 TimeZone tz)

Given a start time and end time with a recurrence rule and a timezone, all periods of the recurrence rule are calculated taken daylight saving time into account.

Parameters:

startCalTz - , Calendar date time of the recurrence in the timezone of the scheduled CA

endCalTz - , Calendar date time of the recurrence in the timezone of the scheduled CA

duration - , the length of each event

recur - , the recurrence rule (based on the Start time zone, including start hour and days of week)

tz - , the timezone of the scheduled CA

Returns:

a list of event Periods that match the rule and start and end times

schedulingIntervalsOverlap

public static boolean schedulingIntervalsOverlap(Date start1,
 Date end1,
 Date start2,
 Date end2)

Check if two intervals (for example, for two scheduled events), overlap.

Parameters:

start1 - start of first interval

end1 - end of first interval

start2 - start of second interval

end2 - end of second interval

Returns:

true if they overlap, false if they don't
