# isFinal

Whether this result is final at the time it is produced.

```
var isFinal: Bool { get }
```

## Discussion

- If `true`, then this result is final. There will be no later result over its range.
- If `false`, then this result is volatile. There may or may not be a later result over this result’s range. In particular, there is no guarantee that this result will be reissued with this property set to `true`.

Equivalent to `resultsFinalizationTime >= range.end`.
