FileBoolean (Jenkins core 2.452.4 API)

java.lang.Object
- jenkins.util.io.FileBoolean

```
public class FileBoolean
extends Object
```
Uses a presence/absence of a file as a persisted boolean storage.
This is convenient when you need to store just a few bits of infrequently accessed information as you can forget the explicit persistence of it. This class masks I/O problem, so if the persistence fails, you'll get no error report.
