Class ManagedEventBus

java.lang.Object

com.groupon.mesos.util.ManagedEventBus

All Implemented Interfaces:

Closeable, AutoCloseable

public class ManagedEventBus
extends Object
implements Closeable

As the event bus does not allow controlled shutdown, add the ability to "poison" the event bus and wait for the pill to pass through it. It is assumed that the pill is the last event that the bus processes and therefore when it is received, no additional events can be processed.
