@Deprecated(since="5.3", forRemoval=true) public class CronSequenceGenerator extends Object
Deprecated, for removal: This API element is subject to removal in a future version.
as of 5.3, in favor of CronExpression
Date sequence generator for a Crontab pattern, allowing clients to specify a pattern that the sequence matches.

The pattern is a list of six single space-separated fields: representing second, minute, hour, day, month, weekday. Month and weekday names can be given as the first three letters of the English names.

Example patterns:

  • "0 0 * * * *" = the top of every hour of every day.
  • "*/10 * * * * *" = every ten seconds.
  • "0 0 8-10 * * *" = 8, 9 and 10 o'clock of every day.
  • "0 0 6,19 * * *" = 6:00 AM and 7:00 PM every day.
  • "0 0/30 8-10 * * *" = 8:00, 8:30, 9:00, 9:30, 10:00 and 10:30 every day.
  • "0 0 9-17 * * MON-FRI" = on the hour nine-to-five weekdays
  • "0 0 0 25 12 ?" = every Christmas Day at midnight
