java.lang.Object
  java.util.concurrent.AbstractExecutorService
      java.util.concurrent.Executors.DelegatedExecutorService
          java.util.concurrent.Executors.DelegatedScheduledExecutorService

All Implemented Interfaces:

Executor, ExecutorService, ScheduledExecutorService

Enclosing class:

Executors

static class Executors.DelegatedScheduledExecutorService
extends Executors.DelegatedExecutorService
implements ScheduledExecutorService

A wrapper class that exposes only the ExecutorService and ScheduleExecutor methods of a ScheduledExecutorService implementation.

Constructor Summary

Executors.DelegatedScheduledExecutorService(ScheduledExecutorService executor)

Method Summary

<V> ScheduledFuture<V>	schedule(Callable<V> callable, long delay, TimeUnit unit) Creates and executes a ScheduledFuture that becomes enabled after the given delay.
ScheduledFuture<?>	schedule(Runnable command, long delay, TimeUnit unit) Creates and executes a one-shot action that becomes enabled after the given delay.
ScheduledFuture<?>	scheduleAtFixedRate(Runnable command, long initialDelay, long period, 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.
ScheduledFuture<?>	scheduleWithFixedDelay(Runnable command, long initialDelay, long delay, 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

public ScheduledFuture<?> schedule(Runnable command,
                                   long delay,
                                   TimeUnit unit)

Description copied from interface: ScheduledExecutorService

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

Specified by:

schedule in interface ScheduledExecutorService

Parameters:

command - the task to execute.

delay - the time from now to delay execution.

unit - the time unit of the delay parameter.

Returns:

a Future representing pending completion of the task, and whose get() method will return null upon completion.

schedule

public <V> ScheduledFuture<V> schedule(Callable<V> callable,
                                       long delay,
                                       TimeUnit unit)

Description copied from interface: ScheduledExecutorService

Creates and executes a ScheduledFuture that becomes enabled after the given delay.

Specified by:

schedule in interface ScheduledExecutorService

Parameters:

callable - the function to execute.

delay - the time from now to delay execution.

unit - the time unit of the delay parameter.

Returns:

a ScheduledFuture that can be used to extract result or cancel.

scheduleAtFixedRate

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

Description copied from interface: ScheduledExecutorService

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. If any execution of the task encounters an exception, subsequent executions are suppressed. Otherwise, the task will only terminate via cancellation or termination of the executor.

Specified by:

scheduleAtFixedRate in interface ScheduledExecutorService

Parameters:

command - the task to execute.

initialDelay - the time to delay first execution.

period - the period between successive executions.

unit - the time unit of the initialDelay and period parameters

Returns:

a Future representing pending completion of the task, and whose get() method will throw an exception upon cancellation.

scheduleWithFixedDelay

public ScheduledFuture<?> scheduleWithFixedDelay(Runnable command,
                                                 long initialDelay,
                                                 long delay,
                                                 TimeUnit unit)

Description copied from interface: ScheduledExecutorService

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. If any execution of the task encounters an exception, subsequent executions are suppressed. Otherwise, the task will only terminate via cancellation or termination of the executor.

Specified by:

scheduleWithFixedDelay in interface ScheduledExecutorService

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 Future representing pending completion of the task, and whose get() method will throw an exception upon cancellation.
