Class DateBuilder

java.lang.Object
  org.quartz.DateBuilder

public class DateBuilder
extends Object

DateBuilder is used to conveniently create java.util.Date instances that meet particular criteria.

Quartz provides a builder-style API for constructing scheduling-related entities via a Domain-Specific Language (DSL). The DSL can best be utilized through the usage of static imports of the methods on the classes TriggerBuilder, JobBuilder, DateBuilder, JobKey, TriggerKey and the various ScheduleBuilder implementations.

Client code can then use the DSL to write code such as this:

         JobDetail job = newJob(MyJob.class)
             .withIdentity("myJob")
             .build();
             
         Trigger trigger = newTrigger() 
             .withIdentity(triggerKey("myTrigger", "myTriggerGroup"))
             .withSchedule(simpleSchedule()
                 .withIntervalInHours(1)
                 .repeatForever())
             .startAt(futureDate(10, MINUTES))
             .build();
         
         scheduler.scheduleJob(job, trigger);

          be used
Returns:
the new rounded date





evenMinuteDateAfterNow
public static Date evenMinuteDateAfterNow()


 Returns a date that is rounded to the next even minute after the current time.
 
 
 

 For example a current time of 08:13:54 would result in a date
 with the time of 08:14:00. If the date's time is in the 59th minute,
 then the hour (and possibly the day) will be promoted.
 



Returns:
the new rounded date





evenMinuteDate
public static Date evenMinuteDate(Date date)


 Returns a date that is rounded to the next even minute above the given
 date.
 
 
 

 For example an input date with a time of 08:13:54 would result in a date
 with the time of 08:14:00. If the date's time is in the 59th minute,
 then the hour (and possibly the day) will be promoted.
 


Parameters:
date - the Date to round, if null the current time will
          be used
Returns:
the new rounded date





evenMinuteDateBefore
public static Date evenMinuteDateBefore(Date date)


 Returns a date that is rounded to the previous even minute below the 
 given date.

 with the time of 08:13:00.
 


Parameters:
date - the Date to round, if null the current time will
          be used
Returns:
the new rounded date





evenSecondDateAfterNow
public static Date evenSecondDateAfterNow()

 date.
 


Parameters:
date - the Date to round, if null the current time will
          be used
Returns:
the new rounded date





evenSecondDateBefore
public static Date evenSecondDateBefore(Date date)


 Returns a date that is rounded to the previous even second below the
 given date.
 
 
 

 For example an input date with a time of 08:13:54.341 would result in a
 date with the time of 08:13:00.000.
 


Parameters:
date - the Date to round, if null the current time will
          be used
Returns:
the new rounded date





nextGivenMinuteDate
public static Date nextGivenMinuteDate(Date date,
                                       int minuteBase)


 Returns a date that is rounded to the next even multiple of the given
 minute.
 
 
 

 For example an input date with a time of 08:13:54, and an input
 minute-base of 5 would result in a date with the time of 08:15:00. The
 same input date with an input minute-base of 10 would result in a date
 with the time of 08:20:00. But a date with the time 08:53:31 and an
 input minute-base of 45 would result in 09:00:00, because the even-hour
 is the next 'base' for 45-minute intervals.
