Package emissary.roll

Class RollScheduledExecutor

java.lang.Object

java.util.concurrent.AbstractExecutorService

java.util.concurrent.ThreadPoolExecutor

java.util.concurrent.ScheduledThreadPoolExecutor

emissary.roll.RollScheduledExecutor

All Implemented Interfaces:

Executor, ExecutorService, ScheduledExecutorService

public class RollScheduledExecutor
extends ScheduledThreadPoolExecutor

Scheduled Executor to support unhandled execution Exceptions. The intention of Rollable tasks is that they run for the life of the process without exception. We don't track the individual futures to reduce complexity and instead will log uncaught errors here.
