Class ExponentialBackoff

java.lang.Object
org.bitcoinj.utils.ExponentialBackoff
All Implemented Interfaces:
Comparable<ExponentialBackoff>
public class ExponentialBackoff extends Object implements Comparable<ExponentialBackoff>

Tracks successes and failures and calculates a time to retry the operation.

The retries are exponentially backed off, up to a maximum interval. On success the back off interval is reset.
