84 * $Id$ [Apr 5, 2004]
85 *
86 * Defines an iCalendar VEVENT component.
87 *
88 * <pre>
89 * 4.6.1 Event Component
90 *
91 * Component Name: &quot;VEVENT&quot;
92 *
93 * Purpose: Provide a grouping of component properties that describe an
94 * event.
95 *
96 * Format Definition: A &quot;VEVENT&quot; calendar component is defined by the
97 * following notation:
98 *
99 * eventc = &quot;BEGIN&quot; &quot;:&quot; &quot;VEVENT&quot; CRLF
100 * eventprop *alarmc
101 * &quot;END&quot; &quot;:&quot; &quot;VEVENT&quot; CRLF
102 *
103 * eventprop = *(
104 *
105 * ; the following are optional,
106 * ; but MUST NOT occur more than once
107 *
108 * class / created / description / dtstart / geo /
109 * last-mod / location / organizer / priority /
110 * dtstamp / seq / status / summary / transp /
111 * uid / url / recurid /
112 *
113 * ; either 'dtend' or 'duration' may appear in
114 * ; a 'eventprop', but 'dtend' and 'duration'
115 * ; MUST NOT occur in the same 'eventprop'
116 *
117 * dtend / duration /
118 *
119 * ; the following are optional,
120 * ; and MAY occur more than once
121 *
122 * attach / attendee / categories / comment /
123 * contact / exdate / exrule / rstatus / related /
124 * resources / rdate / rrule / x-prop
125 *
126 * )
127 * </pre>
128 *
129 * Example 1 - Creating a new all-day event:
130 *
131 * <pre><code>
132 * java.util.Calendar cal = java.util.Calendar.getInstance();
133 * cal.set(java.util.Calendar.MONTH, java.util.Calendar.DECEMBER);
134 * cal.set(java.util.Calendar.DAY_OF_MONTH, 25);
135 *
136 * VEvent christmas = new VEvent(cal.getTime(), &quot;Christmas Day&quot;);
137 *
138 * // initialise as an all-day event..
139 * christmas.getProperties().getProperty(Property.DTSTART).getParameters().add(
140 * Value.DATE);
141 *
142 * // add timezone information..
143 * VTimeZone tz = VTimeZone.getDefault();
144 * TzId tzParam = new TzId(tz.getProperties().getProperty(Property.TZID)
145 * .getValue());
146 * christmas.getProperties().getProperty(Property.DTSTART).getParameters().add(
147 * tzParam);
148 * </code></pre>
149 *
150 * Example 2 - Creating an event of one (1) hour duration:
151 *
152 * <pre><code>
153 * java.util.Calendar cal = java.util.Calendar.getInstance();
154 * // tomorrow..
155 * cal.add(java.util.Calendar.DAY_OF_MONTH, 1);
156 * cal.set(java.util.Calendar.HOUR_OF_DAY, 9);
157 * cal.set(java.util.Calendar.MINUTE, 30);
158 *
159 * VEvent meeting = new VEvent(cal.getTime(), 1000 * 60 * 60, &quot;Progress Meeting&quot;);
160 *
161 * // add timezone information..
162 * VTimeZone tz = VTimeZone.getDefault();
163 * TzId tzParam = new TzId(tz.getProperties().getProperty(Property.TZID)
164 * .getValue());
165 * meeting.getProperties().getProperty(Property.DTSTART).getParameters().add(
166 * tzParam);
167 * </code></pre>
168 *
169 * Example 3 - Retrieve a list of periods representing a recurring event in a specified range:
170 *
171 * <pre><code>
172 * Calendar weekday9AM = Calendar.getInstance();
173 * weekday9AM.set(2005, Calendar.MARCH, 7, 9, 0, 0);
174 * weekday9AM.set(Calendar.MILLISECOND, 0);
175 *
176 * Calendar weekday5PM = Calendar.getInstance();
177 * weekday5PM.set(2005, Calendar.MARCH, 7, 17, 0, 0);
178 * weekday5PM.set(Calendar.MILLISECOND, 0);
179 *
180 * // Do the recurrence until December 31st.
181 * Calendar untilCal = Calendar.getInstance();
182 * untilCal.set(2005, Calendar.DECEMBER, 31);
183 * untilCal.set(Calendar.MILLISECOND, 0);
184 *
185 * // 9:00AM to 5:00PM Rule
186 * Recur recur = new Recur(Recur.WEEKLY, untilCal.getTime());
187 * recur.getDayList().add(WeekDay.MO);
188 * recur.getDayList().add(WeekDay.TU);
189 * recur.getDayList().add(WeekDay.WE);
190 * recur.getDayList().add(WeekDay.TH);
191 * recur.getDayList().add(WeekDay.FR);
192 * recur.setInterval(3);
193 * recur.setWeekStartDay(WeekDay.MO.getDay());
194 * RRule rrule = new RRule(recur);
195 *
196 * Summary summary = new Summary(&quot;TEST EVENTS THAT HAPPEN 9-5 MON-FRI&quot;);
197 *
198 * weekdayNineToFiveEvents = new VEvent();
199 * weekdayNineToFiveEvents.getProperties().add(rrule);
200 * weekdayNineToFiveEvents.getProperties().add(summary);
201 * weekdayNineToFiveEvents.getProperties().add(new DtStart(weekday9AM.getTime()));
202 * weekdayNineToFiveEvents.getProperties().add(new DtEnd(weekday5PM.getTime()));
203 *
204 * // Test Start 04/01/2005, End One month later.
205 * // Query Calendar Start and End Dates.
206 * Calendar queryStartDate = Calendar.getInstance();
207 * queryStartDate.set(2005, Calendar.APRIL, 1, 14, 47, 0);
208 * queryStartDate.set(Calendar.MILLISECOND, 0);
209 * Calendar queryEndDate = Calendar.getInstance();
210 * queryEndDate.set(2005, Calendar.MAY, 1, 11, 15, 0);
211 * queryEndDate.set(Calendar.MILLISECOND, 0);
212 *
213 * // This range is monday to friday every three weeks, starting from
214 * // March 7th 2005, which means for our query dates we need
215 * // April 18th through to the 22nd.
216 * PeriodList periods = weekdayNineToFiveEvents.getPeriods(queryStartDate
217 * .getTime(), queryEndDate.getTime());
218 * </code></pre>
