Method Summary

Modifier and Type	Method	Description
final ScheduledFuture<?>	schedule(Runnable command, long delay, TimeUnit unit)	Creates and executes a one-shot action that becomes enabled after the given delay.
final <V> ScheduledFuture<V>	schedule(Callable<V> callable, long delay, TimeUnit unit)	Creates and executes a ScheduledFuture that becomes enabled after the given delay.
final 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.
final 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.
void	shutdown()	Starts the shutdown process.

Constructor Details

ShutdownableScheduledExecutorServiceImpl

public ShutdownableScheduledExecutorServiceImpl(@Nonnull
 E executor)

Method Details

shutdown

public void shutdown()

Description copied from interface: Shutdownable

Starts the shutdown process. It is recommended to perform the actual shutdown activity in a separate thread from the thread that calls shutdown

Specified by:

shutdown in interface ExecutorService

Specified by:

shutdown in interface Shutdownable

Overrides:

shutdown in class ShutdownableExecutorServiceImpl<E extends ScheduledExecutorService>

See Also:

• ExecutorService.shutdown()

schedule

@Nonnull
public final ScheduledFuture<?> schedule(@Nonnull
 Runnable command,
 long delay,
 @Nonnull
 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

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 ScheduledFuture representing pending completion of the task and whose get() method will return null upon completion

See Also:

• ScheduledExecutorService.schedule(Runnable, long, java.util.concurrent.TimeUnit)

schedule

@Nonnull
public final <V> ScheduledFuture<V> schedule(@Nonnull
 Callable<V> callable,
 long delay,
 @Nonnull
 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

Specified by:

schedule in interface ScheduledExecutorService

Type Parameters:

V - the type of the callable's result

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

See Also:

• ScheduledExecutorService.schedule(java.util.concurrent.Callable, long, java.util.concurrent.TimeUnit)

scheduleAtFixedRate

@Nonnull
public final ScheduledFuture<?> scheduleAtFixedRate(@Nonnull
 Runnable command,
 long initialDelay,
 long period,
 @Nonnull
 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. If any execution of this task takes longer than its period, then subsequent executions may start late, but will not concurrently execute.

Specified by:

scheduleAtFixedRate in interface ScheduledExecutorService

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

See Also:

• ScheduledExecutorService.scheduleAtFixedRate(Runnable, long, long, java.util.concurrent.TimeUnit)

scheduleWithFixedDelay

@Nonnull
public final ScheduledFuture<?> scheduleWithFixedDelay(@Nonnull
 Runnable command,
 long initialDelay,
 long delay,
 @Nonnull
 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

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

• ScheduledExecutorService.scheduleWithFixedDelay(Runnable, long, long, java.util.concurrent.TimeUnit)
