Examples of org.quartz.CronTrigger

org.quartz.CronTrigger

A concrete {@link Trigger} that is used to fire a {@link org.quartz.JobDetail} at given moments in time, defined with Unix 'cron-like' definitions.

For those unfamiliar with "cron", this means being able to create a firing schedule such as: "At 8:00am every Monday through Friday" or "At 1:30am every last Friday of the month".

The format of a "Cron-Expression" string is documented on the {@link org.quartz.CronExpression} class.

Here are some full examples:

Expression		Meaning
`"0 0 12 * * ?"`		`Fire at 12pm (noon) every day`
`"0 15 10 ? * *"`		`Fire at 10:15am every day`
`"0 15 10 * * ?"`		`Fire at 10:15am every day`
`"0 15 10 * * ? *"`		`Fire at 10:15am every day`
`"0 15 10 * * ? 2005"`		`Fire at 10:15am every day during the year 2005`
`"0 * 14 * * ?"`		`Fire every minute starting at 2pm and ending at 2:59pm, every day`
`"0 0/5 14 * * ?"`		`Fire every 5 minutes starting at 2pm and ending at 2:55pm, every day`
`"0 0/5 14,18 * * ?"`		`Fire every 5 minutes starting at 2pm and ending at 2:55pm, AND fire every 5 minutes starting at 6pm and ending at 6:55pm, every day`
`"0 0-5 14 * * ?"`		`Fire every minute starting at 2pm and ending at 2:05pm, every day`
`"0 10,44 14 ? 3 WED"`		`Fire at 2:10pm and at 2:44pm every Wednesday in the month of March.`
`"0 15 10 ? * MON-FRI"`		`Fire at 10:15am every Monday, Tuesday, Wednesday, Thursday and Friday`
`"0 15 10 15 * ?"`		`Fire at 10:15am on the 15th day of every month`
`"0 15 10 L * ?"`		`Fire at 10:15am on the last day of every month`
`"0 15 10 ? * 6L"`		`Fire at 10:15am on the last Friday of every month`
`"0 15 10 ? * 6L"`		`Fire at 10:15am on the last Friday of every month`
`"0 15 10 ? * 6L 2002-2005"`		`Fire at 10:15am on every last friday of every month during the years 2002, 2003, 2004 and 2005`
`"0 15 10 ? * 6#3"`		`Fire at 10:15am on the third Friday of every month`

Pay attention to the effects of '?' and '*' in the day-of-week and day-of-month fields!

NOTES:

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).
Be careful when setting fire times between mid-night and 1:00 AM - "daylight savings" can cause a skip or a repeat depending on whether the time moves back or jumps forward.
