1.59 - *
1.60 - * Defines an iCalendar calendar.
1.61 - *
1.62 - * <pre>
1.63 - * 4.6 Calendar Components
1.64 - *
1.65 - * The body of the iCalendar object consists of a sequence of calendar
1.66 - * properties and one or more calendar components. The calendar
1.67 - * properties are attributes that apply to the calendar as a whole. The
1.68 - * calendar components are collections of properties that express a
1.69 - * particular calendar semantic. For example, the calendar component can
1.70 - * specify an event, a to-do, a journal entry, time zone information, or
1.71 - * free/busy time information, or an alarm.
1.72 - *
1.73 - * The body of the iCalendar object is defined by the following
1.74 - * notation:
1.75 - *
1.76 - * icalbody = calprops component
1.77 - *
1.78 - * calprops = 2*(
1.79 - *
1.80 - * ; 'prodid' and 'version' are both REQUIRED,
1.81 - * ; but MUST NOT occur more than once
1.82 - *
1.83 - * prodid /version /
1.84 - *
1.85 - * ; 'calscale' and 'method' are optional,
1.86 - * ; but MUST NOT occur more than once
1.87 - *
1.88 - * calscale /
1.89 - * method /
1.90 - *
1.91 - * x-prop
1.92 - *
1.93 - * )
1.94 - *
1.95 - * component = 1*(eventc / todoc / journalc / freebusyc /
1.96 - * / timezonec / iana-comp / x-comp)
1.97 - *
1.98 - * iana-comp = "BEGIN" ":" iana-token CRLF
1.99 - *
1.100 - * 1*contentline
1.101 - *
1.102 - * "END" ":" iana-token CRLF
1.103 - *
1.104 - * x-comp = "BEGIN" ":" x-name CRLF
1.105 - *
1.106 - * 1*contentline
1.107 - *
1.108 - * "END" ":" x-name CRLF
1.109 - * </pre>
1.110 - *
1.111 - * Example 1 - Creating a new calendar:
1.112 - *
1.113 - * <pre><code>
1.114 - * Calendar calendar = new Calendar();
1.115 - * calendar.getProperties().add(new ProdId("-//Ben Fortuna//iCal4j 1.0//EN"));
1.116 - * calendar.getProperties().add(Version.VERSION_2_0);
1.117 - * calendar.getProperties().add(CalScale.GREGORIAN);
1.118 - *
1.119 - * // Add events, etc..
1.120 - * </code></pre>
