org.apache.cassandra.concurrent
Class DebuggableScheduledThreadPoolExecutor

java.lang.Object
  java.util.concurrent.AbstractExecutorService
      java.util.concurrent.ThreadPoolExecutor
          java.util.concurrent.ScheduledThreadPoolExecutor
              org.apache.cassandra.concurrent.DebuggableScheduledThreadPoolExecutor

All Implemented Interfaces:

java.util.concurrent.Executor, java.util.concurrent.ExecutorService, java.util.concurrent.ScheduledExecutorService

public class DebuggableScheduledThreadPoolExecutor
extends java.util.concurrent.ScheduledThreadPoolExecutor

Like DebuggableThreadPoolExecutor, DebuggableScheduledThreadPoolExecutor always logs exceptions from the tasks it is given, even if Future.get is never called elsewhere. DebuggableScheduledThreadPoolExecutor also catches exceptions during Task execution so that they don't supress subsequent invocations of the task.
