Class BackoffSleeper

java.lang.Object
  org.skyscreamer.nevado.jms.util.BackoffSleeper

public class BackoffSleeper
extends Object

This "sleeper" sleeps and backs off over time until it is reset. It is used when looking for messages, so active destinations can be checked more frequently for better response. Less active destinations will be checked less frequently as the sleeper backs off, to save AWS costs and unnecessary network calls.
