michael@0 56 *
michael@0 57 * Defines an iCalendar calendar.
michael@0 58 *
michael@0 59 * <pre>
michael@0 60 * 4.6 Calendar Components
michael@0 61 *
michael@0 62 * The body of the iCalendar object consists of a sequence of calendar
michael@0 63 * properties and one or more calendar components. The calendar
michael@0 64 * properties are attributes that apply to the calendar as a whole. The
michael@0 65 * calendar components are collections of properties that express a
michael@0 66 * particular calendar semantic. For example, the calendar component can
michael@0 67 * specify an event, a to-do, a journal entry, time zone information, or
michael@0 68 * free/busy time information, or an alarm.
michael@0 69 *
michael@0 70 * The body of the iCalendar object is defined by the following
michael@0 71 * notation:
michael@0 72 *
michael@0 73 * icalbody = calprops component
michael@0 74 *
michael@0 75 * calprops = 2*(
michael@0 76 *
michael@0 77 * ; 'prodid' and 'version' are both REQUIRED,
michael@0 78 * ; but MUST NOT occur more than once
michael@0 79 *
michael@0 80 * prodid /version /
michael@0 81 *
michael@0 82 * ; 'calscale' and 'method' are optional,
michael@0 83 * ; but MUST NOT occur more than once
michael@0 84 *
michael@0 85 * calscale /
michael@0 86 * method /
michael@0 87 *
michael@0 88 * x-prop
michael@0 89 *
michael@0 90 * )
michael@0 91 *
michael@0 92 * component = 1*(eventc / todoc / journalc / freebusyc /
michael@0 93 * / timezonec / iana-comp / x-comp)
michael@0 94 *
michael@0 95 * iana-comp = &quot;BEGIN&quot; &quot;:&quot; iana-token CRLF
michael@0 96 *
michael@0 97 * 1*contentline
michael@0 98 *
michael@0 99 * &quot;END&quot; &quot;:&quot; iana-token CRLF
michael@0 100 *
michael@0 101 * x-comp = &quot;BEGIN&quot; &quot;:&quot; x-name CRLF
michael@0 102 *
michael@0 103 * 1*contentline
michael@0 104 *
michael@0 105 * &quot;END&quot; &quot;:&quot; x-name CRLF
michael@0 106 * </pre>
michael@0 107 *
michael@0 108 * Example 1 - Creating a new calendar:
michael@0 109 *
michael@0 110 * <pre><code>
michael@0 111 * Calendar calendar = new Calendar();
michael@0 112 * calendar.getProperties().add(new ProdId(&quot;-//Ben Fortuna//iCal4j 1.0//EN&quot;));
michael@0 113 * calendar.getProperties().add(Version.VERSION_2_0);
michael@0 114 * calendar.getProperties().add(CalScale.GREGORIAN);
michael@0 115 *
michael@0 116 * // Add events, etc..
michael@0 117 * </code></pre>
