sked contains java code related to scheduling.
Cron expression parsing is based on the GNU crontab manpage that can be found
The following extensions are used:
- a mandatory field is added at the begining: seconds.
- a special string is added: @minutely
- a special character is added: ? to choose between dayOfMonth and dayOfWeek
The ? special char has the same behavior as in the Quartz Scheduler expression.
The wikipedia page http://en.wikipedia.org/wiki/CRON_expression explains Quartz
Scheduler expression, not simple cron expressions. You'll find there about the ?
special char and maybe that some other extensions you would like to use are missing
in this project.
The project is hosted in maven central.
