iCal4j Template - Groupware: Meeting

Perhaps the most common use of iCalendar is to define and share meeting invites. A Meeting is a closed invitation to select recipients in order for collaborative discussion or other activities. This template may be used to create or modify VEVENT objects to conform with conventional approaches to defining meeting invites.

Examples

Assuming we use vCard to represent meeting participants, we can construct a new meeting:

VCard organizer = ...
VCard chair = ...

VEvent meeting = new Meeting().organizer(organizer)
            .chair(new Contact(chair))
            .start(LocalDate.of(2023, 11, 13).atStartOfDay())
            .duration(Duration.ofMinutes(30)).apply();

The result is something like this:

BEGIN:VEVENT
