Method Summary

Modifier and Type	Method and Description
public final ScheduledFuture<?>	schedule(Runnable the task to execute command, long the time from now to delay execution delay, TimeUnit the time unit of the delay parameter unit) Implements java.util.concurrent.ScheduledExecutorService.schedule. Submits a one-shot task that becomes enabled after the given delay.
public final <V extends @Nullable Object> ScheduledFuture<V>	schedule(Callable<V> the function to execute task, long the time from now to delay execution delay, TimeUnit the time unit of the delay parameter unit) Implements java.util.concurrent.ScheduledExecutorService.schedule. Submits a value-returning one-shot task that becomes enabled after the given delay.
public final ScheduledFuture<?>	scheduleAtFixedRate(Runnable the task to execute command, long the time to delay first execution initialDelay, long the period between successive executions period, TimeUnit the time unit of the initialDelay and period parameters unit) Implements java.util.concurrent.ScheduledExecutorService.scheduleAtFixedRate. Submits a periodic action that becomes enabled first after the given initial delay, and subsequently with the given period; that is, executions will commence after `initialDelay`, then `initialDelay + period`, then `initialDelay + 2 * period`, and so on.
public final ScheduledFuture<?>	scheduleWithFixedDelay(Runnable the task to execute command, long the time to delay first execution initialDelay, long the delay between the termination of one execution and the commencement of the next delay, TimeUnit the time unit of the initialDelay and delay parameters unit) Implements java.util.concurrent.ScheduledExecutorService.scheduleWithFixedDelay. Submits a periodic action that becomes enabled first after the given initial delay, and subsequently with the given delay between the termination of one execution and the commencement of the next.

public final <V extends @Nullable Object> ScheduledFuture<V> schedule(Callable<V> task, long delay, TimeUnit unit)

Implements java.util.concurrent.ScheduledExecutorService.schedule.

Submits a value-returning one-shot task that becomes enabled after the given delay.

Parameters

<V>: the type of the callable's result
task:Callable<V>: the function to execute
delay:long: the time from now to delay execution
unit:TimeUnit: the time unit of the delay parameter

scheduleAtFixedRate	back to summary
public final ScheduledFuture<?> scheduleAtFixedRate(Runnable command, long initialDelay, long period, TimeUnit unit) Implements java.util.concurrent.ScheduledExecutorService.scheduleAtFixedRate. Doc from java.util.concurrent.ScheduledExecutorService.scheduleAtFixedRate. Submits a periodic action that becomes enabled first after the given initial delay, and subsequently with the given period; that is, executions will commence after `initialDelay`, then `initialDelay + period`, then `initialDelay + 2 * period`, and so on. The sequence of task executions continues indefinitely until one of the following exceptional completions occur: The task is explicitly cancelled via the returned future. The executor terminates, also resulting in task cancellation. An execution of the task throws an exception. In this case calling `get` on the returned future will throw `ExecutionException`, holding the exception as its cause. Subsequent executions are suppressed. Subsequent calls to `isDone()` on the returned future will return `true`. If any execution of this task takes longer than its period, then subsequent executions may start late, but will not concurrently execute. Parameters command:Runnable the task to execute initialDelay:long the time to delay first execution period:long the period between successive executions unit:TimeUnit the time unit of the initialDelay and period parameters Returns:ScheduledFuture<?> a ScheduledFuture representing pending completion of the series of repeated tasks. The future's `get()` method will never return normally, and will throw an exception upon task cancellation or abnormal termination of a task execution. Annotations @Override

public final ScheduledFuture<?> scheduleAtFixedRate(Runnable command, long initialDelay, long period, TimeUnit unit)

Implements java.util.concurrent.ScheduledExecutorService.scheduleAtFixedRate.

Doc from java.util.concurrent.ScheduledExecutorService.scheduleAtFixedRate.

Submits a periodic action that becomes enabled first after the given initial delay, and subsequently with the given period; that is, executions will commence after initialDelay, then initialDelay + period, then initialDelay + 2 * period, and so on.

The sequence of task executions continues indefinitely until one of the following exceptional completions occur:

The task is explicitly cancelled via the returned future.
The executor terminates, also resulting in task cancellation.
An execution of the task throws an exception. In this case calling get on the returned future will throw ExecutionException, holding the exception as its cause.

Subsequent executions are suppressed. Subsequent calls to isDone() on the returned future will return true.

If any execution of this task takes longer than its period, then subsequent executions may start late, but will not concurrently execute.

Parameters

command:Runnable: the task to execute
initialDelay:long: the time to delay first execution
period:long: the period between successive executions
unit:TimeUnit: the time unit of the initialDelay and period parameters

Returns:ScheduledFuture<?>

a ScheduledFuture representing pending completion of the series of repeated tasks. The future's get() method will never return normally, and will throw an exception upon task cancellation or abnormal termination of a task execution.

public final ScheduledFuture<?> scheduleWithFixedDelay(Runnable command, long initialDelay, long delay, TimeUnit unit) Implements java.util.concurrent.ScheduledExecutorService.scheduleWithFixedDelay. Doc from java.util.concurrent.ScheduledExecutorService.scheduleWithFixedDelay. Submits a periodic action that becomes enabled first after the given initial delay, and subsequently with the given delay between the termination of one execution and the commencement of the next. The sequence of task executions continues indefinitely until one of the following exceptional completions occur: The task is explicitly cancelled via the returned future. The executor terminates, also resulting in task cancellation. An execution of the task throws an exception. In this case calling `get` on the returned future will throw `ExecutionException`, holding the exception as its cause. Subsequent executions are suppressed.
