- * Provides a parser and evaluator for unix-like cron expressions. Cron
- * expressions provide the ability to specify complex time combinations such as
- * "At 8:00am every Monday through Friday" or "At 1:30am every
- * last Friday of the month".
- * <P>
- * Cron expressions are comprised of 6 required fields and one optional field
- * separated by white space. The fields respectively are described as follows:

- * <P>
- * The '*' character is used to specify all values. For example, "*"
- * in the minute field means "every minute".
- * <P>
- * The '?' character is allowed for the day-of-month and day-of-week fields. It
- * is used to specify 'no specific value'. This is useful when you need to
- * specify something in one of the two fileds, but not the other.
- * <P>
- * The '-' character is used to specify ranges For example "10-12" in
- * the hour field means "the hours 10, 11 and 12".
- * <P>
- * The ',' character is used to specify additional values. For example
- * "MON,WED,FRI" in the day-of-week field means "the days Monday,
- * Wednesday, and Friday".
- * <P>
- * The '/' character is used to specify increments. For example "0/15"
- * in the seconds field means "the seconds 0, 15, 30, and 45". And
- * "5/15" in the seconds field means "the seconds 5, 20, 35, and
- * 50". Specifying '*' before the '/' is equivalent to specifying 0 is
- * the value to start with. Essentially, for each field in the expression, there
- * is a set of numbers that can be turned on or off. For seconds and minutes,
- * the numbers range from 0 to 59. For hours 0 to 23, for days of the month 0 to
- * 31, and for months 1 to 12. The "/" character simply helps you turn
- * on every "nth" value in the given set. Thus "7/6" in the
- * month field only turns on month "7", it does NOT mean every 6th
- * month, please note that subtlety.
- * <P>
- * The 'L' character is allowed for the day-of-month and day-of-week fields.
- * This character is short-hand for "last", but it has different
- * meaning in each of the two fields. For example, the value "L" in
- * the day-of-month field means "the last day of the month" - day 31
- * for January, day 28 for February on non-leap years. If used in the
- * day-of-week field by itself, it simply means "7" or
- * "SAT". But if used in the day-of-week field after another value, it
- * means "the last xxx day of the month" - for example "6L"
- * means "the last friday of the month". When using the 'L' option, it
- * is important not to specify lists, or ranges of values, as you'll get
- * confusing results.
- * <P>
- * The 'W' character is allowed for the day-of-month field. This character
- * is used to specify the weekday (Monday-Friday) nearest the given day. As an
- * example, if you were to specify "15W" as the value for the
- * day-of-month field, the meaning is: "the nearest weekday to the 15th of
- * the month". So if the 15th is a Saturday, the trigger will fire on
- * Friday the 14th. If the 15th is a Sunday, the trigger will fire on Monday the
- * 16th. If the 15th is a Tuesday, then it will fire on Tuesday the 15th.
- * However if you specify "1W" as the value for day-of-month, and the
- * 1st is a Saturday, the trigger will fire on Monday the 3rd, as it will not
- * 'jump' over the boundary of a month's days. The 'W' character can only be
- * specified when the day-of-month is a single day, not a range or list of days.
- * <P>
- * The 'L' and 'W' characters can also be combined for the day-of-month
- * expression to yield 'LW', which translates to "last weekday of the
- * month".
- * <P>
- * The '#' character is allowed for the day-of-week field. This character is
- * used to specify "the nth" XXX day of the month. For example, the
- * value of "6#3" in the day-of-week field means the third Friday of
- * the month (day 6 = Friday and "#3" = the 3rd one in the month).
- * Other examples: "2#1" = the first Monday of the month and
- * "4#5" = the fifth Wednesday of the month. Note that if you specify
- * "#5" and there is not 5 of the given day-of-week in the month, then
- * no firing will occur that month.
- * <P>
- * <!--The 'C' character is allowed for the day-of-month and day-of-week fields.
- * This character is short-hand for "calendar". This means values are
- * calculated against the associated calendar, if any. If no calendar is
- * associated, then it is equivalent to having an all-inclusive calendar. A
- * value of "5C" in the day-of-month field means "the first day included by the
- * calendar on or after the 5th". A value of "1C" in the day-of-week field
- * means "the first day included by the calendar on or after sunday".-->
- * <P>
- * The legal characters and the names of months and days of the week are not
- * case sensitive.
- *
- * <p>
- * <b>NOTES:</b>
- * <ul>
- * <li>Support for specifying both a day-of-week and a day-of-month value is
- * not complete (you'll need to use the '?' character in on of these fields).
- * </li>
- * </ul>
- * </p>
