Method Details

nextTime

public Optional<org.joda.time.DateTime> nextTime(JobTriggerDto trigger)

Calculates the next execution time. This uses the previous JobTriggerDto.nextTime() to calculate the next one based on the trigger schedule.

If this returns an empty Optional, the trigger should not be executed anymore.

Parameters:

trigger - the trigger to use for the calculation

Returns:

the next time this trigger should fire, empty optional if the trigger should not fire anymore

nextTime

public Optional<org.joda.time.DateTime> nextTime(JobTriggerDto trigger,
 org.joda.time.DateTime date)

Calculates the next execution time for a trigger after a given date.

If this returns an empty Optional, the trigger should not be executed anymore.

Parameters:

trigger - the trigger to use for the calculation

date - the date to use when calculating the next time the trigger should fire

Returns:

the next time this trigger should fire, empty optional if the trigger should not fire anymore

nextFutureTime

public Optional<org.joda.time.DateTime> nextFutureTime(JobTriggerDto trigger)

Calculates the next time in the future. This uses the previous JobTriggerDto.nextTime() to calculate the next one based on the trigger schedule. It recalculates the next time until it is in the future.

If this returns an empty Optional, the trigger should not be executed anymore.

Parameters:

trigger - the trigger to use for the calculation

Returns:

the next time this trigger should fire, empty optional if the trigger should not fire anymore
