1.50 -/**
1.51 - * $Id$
1.52 - *
1.53 - * Created: [Apr 6, 2004]
1.54 - *
1.55 - * Defines an RDATE iCalendar component property.
1.56 - *
1.57 - * <pre>
1.58 - * 4.8.5.3 Recurrence Date/Times
1.59 - *
1.60 - * Property Name: RDATE
1.61 - *
1.62 - * Purpose: This property defines the list of date/times for a
1.63 - * recurrence set.
1.64 - *
1.65 - * Value Type: The default value type for this property is DATE-TIME.
1.66 - * The value type can be set to DATE or PERIOD.
1.67 - *
1.68 - * Property Parameters: Non-standard, value data type and time zone
1.69 - * identifier property parameters can be specified on this property.
1.70 - *
1.71 - * Conformance: The property can be specified in "VEVENT", "VTODO",
1.72 - * "VJOURNAL" or "VTIMEZONE" calendar components.
1.73 - *
1.74 - * Description: This property can appear along with the "RRULE" property
1.75 - * to define an aggregate set of repeating occurrences. When they both
1.76 - * appear in an iCalendar object, the recurring events are defined by
1.77 - * the union of occurrences defined by both the "RDATE" and "RRULE".
1.78 - *
1.79 - * The recurrence dates, if specified, are used in computing the
1.80 - * recurrence set. The recurrence set is the complete set of recurrence
1.81 - * instances for a calendar component. The recurrence set is generated
1.82 - * by considering the initial "DTSTART" property along with the "RRULE",
1.83 - * "RDATE", "EXDATE" and "EXRULE" properties contained within the
1.84 - * iCalendar object. The "DTSTART" property defines the first instance
1.85 - * in the recurrence set. Multiple instances of the "RRULE" and "EXRULE"
1.86 - * properties can also be specified to define more sophisticated
1.87 - * recurrence sets. The final recurrence set is generated by gathering
1.88 - * all of the start date/times generated by any of the specified "RRULE"
1.89 - * and "RDATE" properties, and excluding any start date/times which fall
1.90 - * within the union of start date/times generated by any specified
1.91 - * "EXRULE" and "EXDATE" properties. This implies that start date/times
1.92 - * within exclusion related properties (i.e., "EXDATE" and "EXRULE")
1.93 - * take precedence over those specified by inclusion properties (i.e.,
1.94 - * "RDATE" and "RRULE"). Where duplicate instances are generated by the
1.95 - * "RRULE" and "RDATE" properties, only one recurrence is considered.
1.96 - * Duplicate instances are ignored.
1.97 - *
1.98 - * Format Definition: The property is defined by the following notation:
1.99 - *
1.100 - * rdate = "RDATE" rdtparam ":" rdtval *("," rdtval) CRLF
1.101 - *
1.102 - * rdtparam = *(
1.103 - *
1.104 - * ; the following are optional,
1.105 - * ; but MUST NOT occur more than once
1.106 - *
1.107 - * (";" "VALUE" "=" ("DATE-TIME"
1.108 - * / "DATE" / "PERIOD")) /
1.109 - * (";" tzidparam) /
1.110 - *
1.111 - * ; the following is optional,
1.112 - * ; and MAY occur more than once
1.113 - *
1.114 - * (";" xparam)
1.115 - *
1.116 - * )
1.117 - *
1.118 - * rdtval = date-time / date / period
1.119 - * ;Value MUST match value type
1.120 - *
1.121 - * Example: The following are examples of this property:
1.122 - *
1.123 - * RDATE:19970714T123000Z
1.124 - *
1.125 - * RDATE;TZID=US-EASTERN:19970714T083000
1.126 - *
1.127 - * RDATE;VALUE=PERIOD:19960403T020000Z/19960403T040000Z,
1.128 - * 19960404T010000Z/PT3H
1.129 - *
1.130 - * RDATE;VALUE=DATE:19970101,19970120,19970217,19970421
1.131 - * 19970526,19970704,19970901,19971014,19971128,19971129,19971225
