Class ScheduledEventQueue

java.lang.Object
com.yahoo.documentapi.messagebus.ScheduledEventQueue
public class ScheduledEventQueue extends Object
Simple, lightweight event scheduler that does not maintain any executor threads of its own, but rather makes it the responsibility of the caller to run the events as the queue hands them over. Fully thread safe for multiple readers and writers.
