ExponentialBackoff (bitcoinj-core 0.16.1 API)

java.lang.Object
- org.bitcoinj.utils.ExponentialBackoff

All Implemented Interfaces:

java.lang.Comparable<ExponentialBackoff>
```
public class ExponentialBackoff
extends java.lang.Object
implements java.lang.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.
