Class AbstractScheduledService.Scheduler

java.lang.Object

com.google.common.util.concurrent.AbstractScheduledService.Scheduler

Direct Known Subclasses:

AbstractScheduledService.CustomScheduler

Enclosing class:

AbstractScheduledService

public abstract static class AbstractScheduledService.Scheduler
extends Object

A scheduler defines the policy for how the AbstractScheduledService should run its task.

Consider using the newFixedDelaySchedule(java.time.Duration, java.time.Duration) and newFixedRateSchedule(java.time.Duration, java.time.Duration) factory methods, these provide AbstractScheduledService.Scheduler instances for the common use case of running the service with a fixed schedule. If more flexibility is needed then consider subclassing AbstractScheduledService.CustomScheduler.

Method Summary

Modifier and Type	Method and Description
static AbstractScheduledService.Scheduler	newFixedDelaySchedule(Duration initialDelay, Duration delay) Returns a AbstractScheduledService.Scheduler that schedules the task using the ScheduledExecutorService.scheduleWithFixedDelay(java.lang.Runnable, long, long, java.util.concurrent.TimeUnit) method.
static AbstractScheduledService.Scheduler	newFixedDelaySchedule(long initialDelay, long delay, TimeUnit unit) Returns a AbstractScheduledService.Scheduler that schedules the task using the ScheduledExecutorService.scheduleWithFixedDelay(java.lang.Runnable, long, long, java.util.concurrent.TimeUnit) method.
static AbstractScheduledService.Scheduler	newFixedRateSchedule(Duration initialDelay, Duration period) Returns a AbstractScheduledService.Scheduler that schedules the task using the ScheduledExecutorService.scheduleAtFixedRate(java.lang.Runnable, long, long, java.util.concurrent.TimeUnit) method.
static AbstractScheduledService.Scheduler	newFixedRateSchedule(long initialDelay, long period, TimeUnit unit) Returns a AbstractScheduledService.Scheduler that schedules the task using the ScheduledExecutorService.scheduleAtFixedRate(java.lang.Runnable, long, long, java.util.concurrent.TimeUnit) method.

Method Detail

newFixedDelaySchedule

public static AbstractScheduledService.Scheduler newFixedDelaySchedule(Duration initialDelay,
                                                                       Duration delay)

Returns a AbstractScheduledService.Scheduler that schedules the task using the ScheduledExecutorService.scheduleWithFixedDelay(java.lang.Runnable, long, long, java.util.concurrent.TimeUnit) method.

Parameters:

initialDelay - the time to delay first execution

delay - the delay between the termination of one execution and the commencement of the next

Since:

28.0

Returns a AbstractScheduledService.Scheduler that schedules the task using the ScheduledExecutorService.scheduleWithFixedDelay(java.lang.Runnable, long, long, java.util.concurrent.TimeUnit) method.

Parameters:

initialDelay - the time to delay first execution

delay - the delay between the termination of one execution and the commencement of the next

unit - the time unit of the initialDelay and delay parameters

newFixedRateSchedule

                                                                      Duration period)

Returns a AbstractScheduledService.Scheduler that schedules the task using the ScheduledExecutorService.scheduleAtFixedRate(java.lang.Runnable, long, long, java.util.concurrent.TimeUnit) method.

Parameters:

initialDelay - the time to delay first execution

period - the period between successive executions of the task

Since:

28.0
