calculateNextTime

public Optional<org.joda.time.DateTime> calculateNextTime(org.joda.time.DateTime lastExecutionTime,
 org.joda.time.DateTime lastNextTime,
 JobSchedulerClock clock)

Description copied from interface: JobSchedule

Calculates the next time a job should be executed based on the schedule implementation. If this returns an empty Optional, there will be no next execution time. (e.g. for one-off jobs)

The lastExecutionTime parameter is the last execution time of the trigger. This can be used to detect if the trigger has been executed way later than the lastNextTime.

The lastNextTime parameter is the last nextTime of the job trigger. This can be used to calculate the new next time. Using the previous nextTime as base for the new one is more accurate than using the current time. (e.g. because of delayed execution and job duration)

Specified by:

calculateNextTime in interface JobSchedule

Parameters:

lastExecutionTime - the last execution time of a trigger

lastNextTime - the base time, chosen by the caller (mostly last nextTime)

Returns:

filled optional with the next execution time, empty optional if there is no next execution time

toDBUpdate

public Optional<Map<String,Object>> toDBUpdate(String fieldPrefix)

Description copied from interface: JobSchedule

Returns a map with the schedule data. This can be used to update a MongoDB document with schedule data. (see JacksonDBCollection#update())

Specified by:

toDBUpdate in interface JobSchedule

Parameters:

fieldPrefix - the field prefix to use for the map key

Returns:

filled optional with a map, empty optional if there is no update data
