Detailed Description
Represents recurrences for KAlarm.
This class represents the restricted range of recurrence types which are handled by KAlarm, and translates between these and the libkcalendarcore Recurrence class. In particular, it handles yearly recurrences on 29th February in nonleap years specially:
KARecurrence allows annual 29th February recurrences to fall on 28th February or 1st March, or not at all, in nonleap years. It allows such 29th February recurrences to be combined with the 29th of other months in a simple way, represented simply as the 29th of multiple months including February. For storage in the libkcalendarcore calendar, the 29th day of the month recurrence for other months is combined with a lastdayofFebruary or a 60thdayoftheyear recurrence rule, thereby conforming to RFC2445.

Member Function Documentation
void KAlarmCal::KARecurrence::addMonthlyDate  (  short  day  ) 
Adds a date (e.g.
the 15th of each month) to the monthly day recurrence list.
 Parameters

day the date in the month to recur.
Definition at line 784 of file karecurrence.cpp.
void KAlarmCal::KARecurrence::addMonthlyPos  (  short  pos, 
const QBitArray &  days  
) 
Adds a position (e.g.
first monday) to the monthly recurrence rule.
 Parameters

pos the position in the month for the recurrence, with valid values being 15 (5 weeks max in a month). days the days for the position to recur on (bit 0 = Monday). Example: pos = 2, and bits 0 and 2 are set in days: the rule is to repeat every 2nd Monday and Wednesday in the month.
Definition at line 774 of file karecurrence.cpp.
void KAlarmCal::KARecurrence::addWeeklyDays  (  const QBitArray &  days  ) 
Adds days to the weekly day recurrence list.
 Parameters

days a 7 bit array indicating which days on which to recur (bit 0 = Monday).
Definition at line 749 of file karecurrence.cpp.
void KAlarmCal::KARecurrence::addYearlyDate  (  int  date  ) 
Adds date within a yearly recurrence.
The month(s) for the recurrence can be specified with addYearlyMonth(), otherwise the month of the start date is used.
By default infinite recurrence is used. To set an end date use the method setEndDate and to set the number of occurrences use setDuration.
 Parameters

date the day of the month for the event
Definition at line 759 of file karecurrence.cpp.
void KAlarmCal::KARecurrence::addYearlyDay  (  int  day  ) 
Adds day number of year within a yearly recurrence.
By default infinite recurrence is used. To set an end date use the method setEndDate and to set the number of occurrences use setDuration.
 Parameters

day the day of the year for the event. E.g. if day is 60, this means Feb 29 in leap years and March 1 in nonleap years.
Definition at line 754 of file karecurrence.cpp.
void KAlarmCal::KARecurrence::addYearlyMonth  (  short  month  ) 
Adds month in yearly recurrence.
You can specify specific day numbers within the months (by calling addYearlyDate()) or specific day positions within the month (by calling addYearlyPos).
 Parameters

month the month in which the event will recur.
Definition at line 764 of file karecurrence.cpp.
void KAlarmCal::KARecurrence::addYearlyPos  (  short  pos, 
const QBitArray &  days  
) 
Adds position within month/year within a yearly recurrence.
If months are specified (via addYearlyMonth()), the parameters are understood as position within these months, 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.
 Parameters

pos the position in the month/year for the recurrence, with valid values being 1 to 53 and 1 to 53 (53 weeks max in a year). days the days for the position to recur on (bit 0 = Monday). Example: pos = 2, and bits 0 and 2 are set in days If months are specified (via addYearlyMonth), e.g. March, the rule is to repeat every year on the 2nd Monday and Wednesday of March. If no months are specified, the fule is to repeat every year on the 2nd Monday and Wednesday of the year.
Definition at line 769 of file karecurrence.cpp.
bool KAlarmCal::KARecurrence::allDay  (  )  const 
Set whether the recurrence has no time, just a date.
Allday means – according to rfc2445 – that the event has no time associated. N.B. This property is derived by default from whether setStartDateTime() is called with a dateonly or date/time parameter.
 Returns
 whether the recurrence has a time (false) or it is just a date (true).

Definition at line 597 of file karecurrence.cpp.
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

oldSpec the time specification which provides the clock times newSpec the new time specification
Definition at line 1221 of file karecurrence.cpp.

Definition at line 587 of file karecurrence.cpp.
DateTimeList KAlarmCal::KARecurrence::timesInInterval  (  const KADateTime &  start, 
const KADateTime &  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 KADateTime value. If you need further values, call the method again with a start time set to just after the last valid time returned.
