All day event?

[Anonymous]

Thanks for the iCal parser. It will save me a ton of work. I have a couple of questions (which I also asked in an earlier question I had posted in response to your answer. So, feel free to skip it if you get to those first).

1. When parsing an iCal, how can I find if VEvent is an all day event? I looked at the class methods and I don't see any which returns the value. Am I just missing something?
2. I would like to get the timezone info, but the following code returns null.
   ICalReader iCalReader = new ICalReader(f);
   TimezoneInfo tzi = iCalReader.getTimezoneInfo();

Thank you for your help.

There's nothing in the iCalendar specification that allows you to flag an event as an "all-day" event. You have to just look at the start and end dates, and judge for yourself. I think most iCalendar consumers consider an event to be "all-day" if the start and end dates are 1 day apart. Something like this:

public static boolean isAllDay(VEvent event){
  ICalDate start = event.getDateStart().getValue();
  ICalDate end = event.getDateEnd().getValue();
  if (start.hasTime() || end.hasTime()){
    return false;
  }

  Calendar c = Calendar.getInstance();
  c.setTime(start);
  c.add(Calendar.DATE, 1);
  Date expectedEnd = c.getTime();

  return end.equals(expectedEnd);
}

I would like to get the timezone info, but the following code returns null.

You must call "getTimezoneInfo()" after calling "readNext()".

ICalReader reader = ...
ICalendar ical = reader.readNext();
TimezoneInfo tzinfo = reader.getTimezoneInfo();

Thank you for the tip re. time zone. Re. all day event, is this not standard?

No, that is not a standard iCalendar property. Microsoft products probably recognize it, but other iCalendar consumers may not.
