public class DecoratedScheduledExecutorService
extends DecoratedExecutorService
implements ScheduledExecutorService

A ScheduledExecutorService where all tasks are automatically decorated before being submitted to a delegate executor service. Extends DecoratedExecutorService to handle the ExecutorService methods.

The JDK scheduleAtFixedRate(java.lang.Runnable, long, long, java.util.concurrent.TimeUnit) and scheduleWithFixedDelay(java.lang.Runnable, long, long, java.util.concurrent.TimeUnit) methods are not supported; use ScheduledExecutors instead.
