| * By default, this constructor specifies day-of-week-in-month rules. That |
| * is, if the {@code startDay} is 1, and the {@code startDayOfWeek} is {@code SUNDAY}, then this |
| * indicates the first Sunday in the {@code startMonth}. A {@code startDay} of -1 likewise |
| * indicates the last Sunday. However, by using negative or zero values for |
| * certain parameters, other types of rules can be specified. |
| * <p> |
| * Day of month: To specify an exact day of the month, such as March 1, set |
| * {@code startDayOfWeek} to zero. |
| * <p> |
| * Day of week after day of month: To specify the first day of the week |
| * occurring on or after an exact day of the month, make the day of the week |
| * negative. For example, if {@code startDay} is 5 and {@code startDayOfWeek} is {@code -MONDAY}, |
| * this indicates the first Monday on or after the 5th day of the |
| * {@code startMonth}. |
| * <p> |
| * Day of week before day of month: To specify the last day of the week |
| * occurring on or before an exact day of the month, make the day of the |
| * week and the day of the month negative. For example, if {@code startDay} is {@code -21} |
| * and {@code startDayOfWeek} is {@code -WEDNESDAY}, this indicates the last Wednesday on or |
| * before the 21st of the {@code startMonth}. |
| * <p> |
