```
public class ScanServerAttemptsImpl
extends Object
```
This class is used to track scan attempts for the ScanServerSelector. Its designed to accept updates concurrently (useful for the batch scanner) and offers a snapshot. When a snapshot is obtained it will not change, this class will still accept updates after generating a snapshot. Snapshots are useful for ensuring that authors of ScanServerSelector plugins do not have to consider strange concurrency issues when writing a plugin.
