All Implemented Interfaces:

ScheduleSequence

public class XMonthlyScheduleSequence
extends Object
implements ScheduleSequence

This class is variation of DefaultSchduleSequence, it adds logic wrapper to dates returned by Quartz util.

Logic wrapper filters dates, to generate schedule for every month, every other month, etc ...

This implementation is very specifically addressed to deal with monthly, quarterly, annually, etc date filtering requirements. Implementation uses org.quartz.TriggerUtils class to generate List of dates from Cron expression.

It uses current time zone, where application is hosted.

Note: Dates used in generating schedule must be wrapped with required time accuracy. e.g. Start Date: 02/01/09 10:10 End Date: 02/05/09 10:10 Generated Dates will be in between 02/01/09 10:10 and 02/05/09 10:10. Any date expected before 02/01/09 10:09 will be ignored. Date 02/01/09 10:00 will be ignored. Any date expected after 02/05/09 10:11 will be ignored. Date 02/05/09 12:00 will be ignored.
