Detailed Description

This class represents a recurrence rule for a calendar incidence.

It manages all recurrence rules, recurrence date/times, exception rules and exception date times that can appear inside calendar items. Each recurrence rule and exception rule is represented as an object of type RecurrenceRule.

For the simple case where at most one recurrence rule is present, this class provides shortcut methods to set the type: setMinutely() setHourly() setDaily() setWeekly() setMonthly() setYearly() to set/get general information about the recurrence: setEndDate() setEndDateTime() duration() durationTo() setDuration() frequency() setFrequency() and to set/get specific information about the recurrence within the interval: days() monthDays() monthPositions() yearDays() yearDates() yearMonths() yearPositions() addMonthlyPos() addMonthlyDate() addYearlyDay() addYearlyDate() addYearlyPos() addYearlyMonth() These are all available so that you don't have to work on the RecurrenceRule objects themselves. In other words, in that simple situation the interface stays almost the same compared to the old Recurrence class, which allowed only one recurrence rule.

As soon as your recurrence consists of multiple recurrence rules or exception rules, you cannot use the methods mentioned above any more (since each rule will have a different type and different settings). If you still call any of them, the set*ly methods will remove all rules and add one rule with the specified type. The add* and the other set* methods will change only the first recurrence rule, but leave the others untouched.

The day of the month can be specified with addYearlyByDate If both a month and a day ar specified with addYearlyMonth and addYearlyDay, the day is understood as day number within the month.

A position (e.g. 3rd Sunday of year/month, or last Friday of year/month) can be specified with addYearlyPos. Again, if a month is specified, this position is understood as within that month, otherwise within the year.

By default infinite recurrence is used. To set an end date use the method setEndDate and to set the number of occurrences use setDuration.

This method clears all recurrence rules and adds one rule with a yearly recurrence. All other recurrence components (recurrence date/times, exception date/times and exception rules) are not modified.

Parameters

freq	the frequency to recur, e.g. 3 for every third year.

◆ setYearlyDate()

void Recurrence::setYearlyDate ( const QList< int > & dates )

◆ setYearlyDay()

void Recurrence::setYearlyDay ( const QList< int > & days )

Definition at line 896 of file recurrence.cpp.

◆ setYearlyMonth()

void Recurrence::setYearlyMonth ( const QList< int > & months )

◆ setYearlyPos()

void Recurrence::setYearlyPos ( const QList< RecurrenceRule::WDayPos > & days )

Definition at line 932 of file recurrence.cpp.

◆ shiftTimes()

void Recurrence::shiftTimes	(	const QTimeZone &	oldZone,
		const QTimeZone &	newZone )

Shift the times of the recurrence so that they appear at the same clock time as before but in a new time zone.

The shift is done from a viewing time zone rather than from the actual recurrence time zone.

For example, shifting a recurrence whose start time is 09:00 America/New York, using an old viewing time zone (oldSpec) of Europe/London, to a new time zone (newSpec) of Europe/Paris, will result in the time being shifted from 14:00 (which is the London time of the recurrence start) to 14:00 Paris time.

Parameters

oldZone	the time specification which provides the clock times
newZone	the new time specification

◆ startDate()

QDate Recurrence::startDate ( ) const

Return the start date/time of the recurrence.

Definition at line 577 of file recurrence.cpp.

◆ startDateTime()

QDateTime Recurrence::startDateTime ( ) const

Return the start date/time of the recurrence (Time for all-day recurrences will be 0:00).

Returns: the current start/time of the recurrence.

Definition at line 153 of file recurrence.cpp.

◆ timesInInterval()

QList< QDateTime > Recurrence::timesInInterval	(	const QDateTime &	start,
		const QDateTime &	end ) const

Returns a list of all the times at which the recurrence will occur between two specified times.

There is a (large) maximum limit to the number of times returned. If due to this limit the list is incomplete, this is indicated by the last entry being set to an invalid QDateTime value. If you need further values, call the method again with a start time set to just after the last valid time returned.

Parameters

start	inclusive start of interval
end	inclusive end of interval

Returns: list of date/time values

Definition at line 1042 of file recurrence.cpp.

◆ unsetRecurs()

void Recurrence::unsetRecurs ( )

Removes all recurrence rules.

Recurrence dates and exceptions are not removed.

Definition at line 539 of file recurrence.cpp.

◆ updated()

void Recurrence::updated ( )

Definition at line 199 of file recurrence.cpp.

◆ weekStart()

int Recurrence::weekStart ( ) const

Returns the first day of the week.

Uses only the first RRULE if present (i.e. a second RRULE as well as all EXRULES are ignored!

Returns: Weekday of the first day of the week (Monday=1 .. Sunday=7)

Definition at line 624 of file recurrence.cpp.

◆ yearDates()

QList< int > Recurrence::yearDates ( ) const

Returns the dates within a yearly recurrence.

Returns: the days of the month for the event. E.g. if the list contains 13, this means the recurrence happens on the 13th of the month. The months for the recurrence can be obtained through yearlyMonths(). If this list is empty, the month of the start date is used.

Definition at line 675 of file recurrence.cpp.

◆ yearDays()

QList< int > Recurrence::yearDays ( ) const

Returns the day numbers within a yearly recurrence.

Returns: the days of the year for the event. E.g. if the list contains 60, this means the recurrence happens on day 60 of the year, i.e. on Feb 29 in leap years and March 1 in non-leap years.

Definition at line 669 of file recurrence.cpp.

◆ yearMonths()

QList< int > Recurrence::yearMonths ( ) const

Returns the months within a yearly recurrence.

Returns: the months for the event. E.g. if the list contains 11, this means the recurrence happens in November. The days for the recurrence can be obtained either through yearDates() if they are given as dates within the month or through yearlyPositions() if they are given as positions within the month. If none is specified, the date of the start date is used.

Definition at line 680 of file recurrence.cpp.

◆ yearPositions()

QList< RecurrenceRule::WDayPos > Recurrence::yearPositions ( ) const

Returns the positions within a yearly recurrence.

Returns: the positions for the event, either within a month (if months are set through addYearlyMonth()) or within the year. E.g. if the list contains {Pos=3, Day=5}, this means the third friday. If a month is set this position is understoodas third Friday in the given months, otherwise as third Friday of the year. Returns list of day positions in months, for a recursYearlyPos recurrence rule.
