Constructor Detail

DefaultBackgroundExecutor

public DefaultBackgroundExecutor(int schedulePoolSize,
                                 int shutdownWaitSeconds,
                                 String namePrefix)

Construct the default implementation of BackgroundExecutor.

Method Detail

execute

public void execute(Runnable r)

Execute a Runnable using a background thread.

Specified by:

execute in interface BackgroundExecutor

executePeriodically

public void executePeriodically(Runnable r,
                                long delay,
                                TimeUnit unit)

Description copied from interface: BackgroundExecutor

Execute a task periodically with a fixed delay between each execution.

For example, execute a runnable every minute.

The delay is the time between executions no matter how long the task took. That is, this method has the same behaviour characteristics as ScheduledExecutorService.scheduleWithFixedDelay(Runnable, long, long, TimeUnit)

Specified by:

executePeriodically in interface BackgroundExecutor

executePeriodically

public void executePeriodically(Runnable r,
                                long initialDelay,
                                long delay,
                                TimeUnit unit)

Description copied from interface: BackgroundExecutor

Execute a task periodically additionally with an initial delay different from delay.

Specified by:

executePeriodically in interface BackgroundExecutor

schedule

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

Description copied from interface: BackgroundExecutor

Schedules a Runnable for one-shot action that becomes enabled after the given delay.

Specified by:

schedule in interface BackgroundExecutor

Returns:

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

schedule

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

Description copied from interface: BackgroundExecutor

Schedules a Callable for one-shot action that becomes enabled after the given delay.

Specified by:

schedule in interface BackgroundExecutor

Returns:

a ScheduledFuture that can be used to extract result or cancel

shutdown

public void shutdown()

Description copied from interface: SpiBackgroundExecutor

Shutdown any associated thread pools.

Specified by:

shutdown in interface SpiBackgroundExecutor
