public interface Scheduler
extends Disposable

Component that can schedule events to execute in the future. Similar to the ScheduledExecutorService

Method Summary

Modifier and Type	Method and Description
Disposable	schedule(java.lang.Runnable command, long delay, java.util.concurrent.TimeUnit unit) Creates and executes a one-shot action that becomes enabled after the given delay.
Disposable	scheduleAtFixedRate(java.lang.Runnable command, long initialDelay, long period, java.util.concurrent.TimeUnit unit) Creates and executes 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.
Disposable	scheduleWithFixedDelay(java.lang.Runnable command, long initialDelay, long delay, java.util.concurrent.TimeUnit unit) Creates and executes 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.

Method Detail

schedule

Disposable schedule(java.lang.Runnable command,
                    long delay,
                    java.util.concurrent.TimeUnit unit)

Creates and executes a one-shot action that becomes enabled after the given delay.

Parameters:

command - the task to execute

delay - the time from now to delay execution

unit - the time unit of the delay parameter

Returns:

a Disposable that can be used to cancel execution

scheduleWithFixedDelay

Disposable scheduleWithFixedDelay(java.lang.Runnable command,
                                  long initialDelay,
                                  long delay,
                                  java.util.concurrent.TimeUnit unit)

Creates and executes 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.

Parameters:

command - the task to execute

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

Returns:

a Disposable that can be used to cancel execution

scheduleAtFixedRate

Disposable scheduleAtFixedRate(java.lang.Runnable command,
                               long initialDelay,
                               long period,
                               java.util.concurrent.TimeUnit unit)

Creates and executes 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 task will only terminate via cancellation or termination of the executor.

Parameters:

command - the task to execute

initialDelay - the time to delay first execution

period - the delay

unit - the time unit of the initialDelay and delay parameters

Returns:

a Disposable that can be used to cancel execution
