FetchStatusCodes (Heritrix 3 3.2.0 API)

All Known Implementing Classes:

FetchStats, FetchWhois
```
public interface FetchStatusCodes
```
Constant flag codes to be used, in lieu of per-protocol codes (like HTTP's 200, 404, etc.), when network/internal/ out-of-band conditions occur. The URISelector may use such codes, along with user-configured options, to determine whether, when, and how many times a CrawlURI might be reattempted.
