Member Function Documentation

addObserver()

void RecurrenceRule::addObserver

(

RuleObserver *

observer

)

Installs an observer.

Whenever some setting of this recurrence object is changed, the recurrenceUpdated( Recurrence* ) method of each observer will be called to inform it of changes.

Parameters

observer

the Recurrence::Observer-derived object, which will be installed as an observer of this object.

Definition at line 895 of file recurrencerule.cpp.

allDay()

bool RecurrenceRule::allDay

(

)

const

Returns whether the start date has no time associated.

All-Day means – according to rfc2445 – that the event has no time associate.

dateMatchesRules()

bool RecurrenceRule::dateMatchesRules

(

const QDateTime &

const

Returns true if the date matches the rules.

It does not necessarily mean that this is an actual occurrence. In particular, the method does not check if the date is after the end date, or if the frequency interval matches.

Parameters

const

Returns -1 if the event recurs infinitely, 0 if the end date is set, otherwise the total number of recurrences, including the initial occurrence.

Definition at line 2096 of file recurrencerule.cpp.

durationTo() [1/2]

int RecurrenceRule::durationTo

(

const QDate &

date

)

const

Returns the number of recurrences up to and including the date specified.

Definition at line 1577 of file recurrencerule.cpp.

durationTo() [2/2]

int RecurrenceRule::durationTo

(

const QDateTime &

dt

)

const

Returns the number of recurrences up to and including the date/time specified.

Definition at line 1555 of file recurrencerule.cpp.

endDt()

QDateTime RecurrenceRule::endDt

(

bool *

result = nullptr

)

const

Returns the date and time of the last recurrence.

An invalid date is returned if the recurrence has no end.

Parameters

result

if non-null, *result is updated to true if successful, or false if there is no recurrence or its end date cannot be determined.

Definition at line 916 of file recurrencerule.cpp.

frequency()

uint RecurrenceRule::frequency

(

)

const

Returns the recurrence frequency, in terms of the recurrence time period type.

Definition at line 2091 of file recurrencerule.cpp.

getNextDate()

QDateTime RecurrenceRule::getNextDate

(

const QDateTime &

preDateTime

)

const

Returns the date and time of the next recurrence, after the specified date/time.

If the recurrence has no time, the next date after the specified date is returned.

Parameters

preDateTime

the date/time after which to find the recurrence.

Returns

date/time of next recurrence, or invalid date if none.

Definition at line 1648 of file recurrencerule.cpp.

getPreviousDate()

QDateTime RecurrenceRule::getPreviousDate

(

const QDateTime &

afterDateTime

)

const

Returns the date and time of the last previous recurrence, before the specified date/time.

If a time later than 00:00:00 is specified and the recurrence has no time, 00:00:00 on the specified date is returned if that date recurs.

Parameters

afterDateTime

the date/time before which to find the recurrence.

Returns

date/time of previous recurrence, or invalid date if none.

Definition at line 1582 of file recurrencerule.cpp.

isReadOnly()

const QDateTime &

endDateTime

Parameters

endDateTime

the ending date/time after which to stop recurring.

setReadOnly()

void RecurrenceRule::setReadOnly

(

bool

readOnly

)

setRecurrenceType()

void RecurrenceRule::setRecurrenceType

(

PeriodType

period

)

Definition at line 907 of file recurrencerule.cpp.

setRRule()

void RecurrenceRule::setRRule

(

const QString &

rrule

)

Set the RRULE string for the rule.

This is merely stored for future reference. The string is not used in any way by the RecurrenceRule.

Parameters

rrule

the RRULE string

Definition at line 2106 of file recurrencerule.cpp.

setStartDt()

void RecurrenceRule::setStartDt

(

const QDateTime &

start

)

Sets the recurrence start date/time.

Note that setting the start date/time does not make the recurrence occur on that date/time, it simply sets a lower limit to when the recurrences take place (this applies only for the by- rules, not for i.e. an hourly rule where the startDt is the first occurrence).

Note that setting start to a date-only value does not make an all-day recurrence: to do this, call setAllDay(true).

Parameters

start

the recurrence's start date and time

Definition at line 987 of file recurrencerule.cpp.

setWeekStart()

void RecurrenceRule::setWeekStart

(

short

weekStart

)

Definition at line 1086 of file recurrencerule.cpp.

shiftTimes()

void RecurrenceRule::shiftTimes	(	const QTimeZone &	oldTz,
		const QTimeZone &	newTz )

Shift the times of the rule 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 rule time zone.

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

Parameters

oldTz	the time specification which provides the clock times
newTz	the new time specification

Definition at line 1095 of file recurrencerule.cpp.

startDt()

QDateTime RecurrenceRule::startDt

(

)

const

Returns the recurrence start date/time.

Note that the recurrence does not necessarily occur on the start date/time. For this to happen, it must actually match the rule.

Definition at line 2081 of file recurrencerule.cpp.

timesInInterval()

QList< QDateTime > RecurrenceRule::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 1710 of file recurrencerule.cpp.

weekStart()

short RecurrenceRule::weekStart

(

)

const

Definition at line 2176 of file recurrencerule.cpp.
