Recurring
This is an abstract base class from which recurring calendar objects are derived. It defines a common
set of properties and methods used to resolve an object to one or more dates based on the combination of
recurrence rules, recurrence dates, exception rules, and exception dates.

Constructors
| RecurringObject | Initializes a new instance of the RecurringObject class |
Properties
| ExceptionDates | This is used to get the Exception Date (EXDATE) properties. There may be more than one. |
| ExceptionRules | This is used to get the Exception Rule (EXRULE) properties. There may be more than one. |
| ExcludeStartDateTime | This property can be used to override the specification and exclude the start date/time if it is not generated by one of the recurrence rule or recurrence date properties. |
| InstanceDuration | This must be implemented to return the duration for the recurring instances |
| IsRecurring | This can be used to see if an item has recurrence information |
| RecurDates | This is used to get the Recur Date (RDATE) properties. There may be more than one. |
| RecurrenceRules | This is used to get the Recurrence Rule (RRULE) properties. There may be more than one. |
| StartDateTime | This must be implemented to return the start date/time property that is used to determine when the first instance occurs. |
| TimeZoneId | This must be implemented to return the time zone ID for the start date |
| Version |
This is overridden to propagate the version to all properties in the object that need it when the
version is set on the item.
(Inherited from CalendarObject) |
| VersionsSupported |
All objects derived from this class must implement this to indicate the specification versions with
which they can be used.
(Inherited from PDIObject) |
Methods
| AllInstances | This method is used to return all recurring instances based on the current settings alone |
| ApplyTimeZone |
This is used to apply the selected time zone to all date/time objects in the component and convert
them to the new time zone.
(Overrides CalendarObjectApplyTimeZone(VTimeZone)) |
| ClearProperties |
The method can be called to clear all current property values from the object. The version is left
unchanged.
(Overrides CalendarObjectClearProperties) |
| Clone |
This must be overridden to allow cloning of a PDI object
(Inherited from PDIObject) |
| Clone(PDIObject) |
This is overridden to allow copying of the additional properties
(Overrides PDIObjectClone(PDIObject)) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| InstancesBetween | This method is used to return all recurring instances between the two specified date/times based on the current settings. |
| LastInstance | This method can be used to quickly determine the end date of an item regardless of whether it uses recurrence or not. |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| OccursOn | This method is used to determine whether or not an instance of the recurrence falls on the specified date/time. |
| PropagateVersion |
This is used to propagate the version to all properties in the object that need it
(Overrides CalendarObjectPropagateVersion) |
| SetTimeZone |
This is used to set the selected time zone in all date/time objects in the component without
modifying the date/time values.
(Overrides CalendarObjectSetTimeZone(VTimeZone)) |
| TimeZonesUsed |
This is used to get a list of time zones used by all owned objects
(Overrides CalendarObjectTimeZonesUsed(StringCollection)) |
| ToString |
Convert the object instance to its string form
(Inherited from CalendarObject) |
| UpdateTimeZoneId |
This is used to replace an old time zone ID with a new time zone ID in all properties of a calendar
object.
(Overrides CalendarObjectUpdateTimeZoneId(String, String)) |
| WriteToStream(TextWriter) |
This can be used to write a calendar object to a PDI data stream
(Inherited from CalendarObject) |
| WriteToStream(TextWriter, StringBuilder) |
This is used to write recurrence properties to a PDI data stream
(Overrides CalendarObjectWriteToStream(TextWriter, StringBuilder)) |
