Recurrence

#include <bb/pim/calendar/Recurrence>

The Recurrence class represents recurrence data for calendar events.

This class specifies how an event repeats. An event that happens over and over (for example, every day, or on working days, or every Monday, Wednesday and Friday) has an associated recurrence rule (that is, event.recurrence().isValid() returns true).

A recurrence may be infinite (no end date or number of occurrences specified). A finite recurrence has an end date or a number of occurrences.

This class is modeled after the ActiveSync Recurrence element (http://msdn.microsoft.com/en-us/library/ee219748%28v=EXCHG.80%29.aspx). It can express as many recurrence patterns as the ActiveSync element, but not as many as the iCalendar RRULE element (http://www.kanzaki.com/docs/ical/rrule.html). For example, it's not possible to define a rule for hourly recurrence with this class.

Public Functions

Recurrence ()

Constructs a new Recurrence.

Since:

BlackBerry 10.0.0

~Recurrence ()

Destructor.

Since:

BlackBerry 10.0.0

Recurrence (

Copy constructor.

This function constructs a Recurrence containing exactly the same values as the provided Recurrence.

Parameters
other

The Recurrence to be copied.
Since:

BlackBerry 10.0.0

Recurrence & operator= (

Assignment operator.

This operator copies all values from the provided Recurrence into this Recurrence.

Parameters
other

The Recurrence from which to copy all values.
Return:

A reference to this Recurrence.

Since:

BlackBerry 10.0.0

QDateTime start ()

Retrieves the start time of this Recurrence.

Return:

The start time of this Recurrence.

Since:

BlackBerry 10.0.0

QDateTime end ()

Retrieves the end time of this Recurrence.

Return:

The end time of this Recurrence.

Since:

BlackBerry 10.0.0

QDateTime until ()

Retrieves the until date of this Recurrence.

This function returns the date when the recurrence ends. A finite recurrence should have an until date or a defined number of occurrences.

Return:

The until date of this Recurrence.

Since:

BlackBerry 10.0.0

QList< QDateTime > exceptions ()

Retrieves the exception dates for this Recurrence.

This function returns the dates of occurrences that were modified (recurrence exceptions) or deleted (recurrence exclusions).

Return:

The exception dates for this Recurrence.

Since:

BlackBerry 10.0.0

Frequency::Type frequency ()

Retrieves the recurrence frequency of this Recurrence.

The frequency is represented by a Frequency object. This object indicates the type of recurrence, and can be one of the following:

  • daily

  • weekly

  • monthly on a day of the week (for example, the first Monday every month)

  • monthly on a date (for example, the 15th day every month)

  • yearly on a week day of a month (for example, the second Sunday of May)

  • yearly on a date (for example, July 1st)

Return:

The recurrence frequency of this Recurrence.

Since:

BlackBerry 10.0.0

int interval ()

Retrieves the recurrence interval of this Recurrence.

The recurrence interval is the number of times a rule must generate a possible date to produce an occurrence.

A recurrence rule and a start date yield a set of possible dates. For example, a daily event that repeats five times starting at July 23rd 2012 has five possible dates. With the default interval value of one, the occurrences for this event will be the 23rd, 24th, 25th, 26th and 27th. With a value of two, the occurrences will be 24th, 26th, 28th, 30th and 1st of August.

Return:

The recurrence interval of this Recurrence.

Since:

BlackBerry 10.0.0

int numberOfOccurrences ()

Retrieves the number of occurrences of this Recurrence.

This function returns the number of repetitions in a finite recurrence.

Return:

The number of occurrences of this Recurrence.

Since:

BlackBerry 10.0.0

int dayInWeek ()

Retrieves the days of the week when this Recurrence repeats.

This value is meaningful only when the frequency is weekly, monthly on a week day, or yearly on a week day of a month.

Each week day has a corresponding value: 1 - Sunday 2 - Monday 4 - Tuesday 8 - Wednesday 16 - Thursday 32 - Friday 64 - Saturday 127 - Last day in the month

The values can be OR'ed together to have rules with multiple days. For example, a recurrence that happens on Tuesday and Thursday should have a value of 4 + 16 = 20.

Return:

The days of the week when this Recurrence repeats.

Since:

BlackBerry 10.0.0

int dayInMonth ()

Retrieves the day of the month when this Recurrence repeats.

This value is meaningful only when the frequency is monthly on a date or yearly on a date.

Return:

The day of the month when this Recurrence repeats.

Since:

BlackBerry 10.0.0

int weekInMonth ()

Retrieves the week in the month when this Recurrence repeats.

This value is meaningful only when the frequency is monthly on a week day or yearly on a week day of a month.

For example, the recurrence rule for an event on the second Sunday of May would have a value of 2 in this attribute.

Return:

The week in the month when this Recurrence repeats.

Since:

BlackBerry 10.0.0

int monthInYear ()

Retrieves the month in the year when this Recurrence repeats.

This value is meaningful only when the frequency is yearly on a date or yearly on a week day of a month.
