Method Summary
`static Date` | `computeEndTimeToAllowParticularNumberOfFirings(OperableTrigger trigg, Calendar cal, int numTimes)` Compute the `Date` that is 1 second after the Nth firing of the given `Trigger`, taking the triger's associated `Calendar` into consideration.
`static List<Date>` | `computeFireTimes(OperableTrigger trigg, Calendar cal, int numTimes)` Returns a list of Dates that are the next fire times of a `Trigger`.
`static List<Date>` | `computeFireTimesBetween(OperableTrigger trigg, Calendar cal, Date from, Date to)` Returns a list of Dates that are the next fire times of a `Trigger` that fall within the given date range.

Method Detail

### computeFireTimes

    public static List<Date> computeFireTimes(OperableTrigger trigg,
                                              Calendar cal,
                                              int numTimes)

  Returns a list of Dates that are the next fire times of a `Trigger`. The input trigger will be cloned before any work is done, so you need not worry about its state being altered by this method.

  Parameters:
    `trigg` - The trigger upon which to do the work
    `cal` - The calendar to apply to the trigger's schedule
    `numTimes` - The number of next fire times to produce
  Returns:
    List of java.util.Date objects

### computeEndTimeToAllowParticularNumberOfFirings

    public static Date computeEndTimeToAllowParticularNumberOfFirings(OperableTrigger trigg,
                                                                      Calendar cal,
                                                                      int numTimes)

  Compute the `Date` that is 1 second after the Nth firing of the given `Trigger`, taking the triger's associated `Calendar` into consideration. The input trigger will be cloned before any work is done, so you need not worry about its state being altered by this method.

  Parameters:
    `trigg` - The trigger upon which to do the work
    `cal` - The calendar to apply to the trigger's schedule
    `numTimes` - The number of next fire times to produce
  Returns:
    the computed Date, or null if the trigger (as configured) will not fire that many times.

### computeFireTimesBetween

    public static List<Date> computeFireTimesBetween(OperableTrigger trigg,
                                                     Calendar cal,
                                                     Date from,
                                                     Date to)

  Returns a list of Dates that are the next fire times of a `Trigger` that fall within the given date range. The input trigger will be cloned before any work is done, so you need not worry about its state being altered by this method.

  NOTE: if this is a trigger that has previously fired within the given date range, then firings which have already occurred will not be listed in the output List.

  Parameters:
    `trigg` - The trigger upon which to do the work
    `cal` - The calendar to apply to the trigger's schedule
    `from` - The starting date at which to find fire times
    `to` - The ending date at which to stop finding fire times
  Returns:
    List of java.util.Date objects
