```csharp
protected Task<IReadOnlyList<TEventBase>> JournaledGrain<TGrainState, RetrieveConfirmedEvents(int fromVersion, int toVersion)
```

Retrieves a segment of the confirmed event sequence, possibly from storage. Throws `System.NotSupportedException` if the events are not available to read. Whether events are available, and for how long, depends on the providers used and how they are configured.

### Parameters

- `fromVersion` (`int`): the position of the event sequence from which to start
- `toVersion` (`int`): the position of the event sequence on which to end

### Returns

a task which returns the sequence of events between the two versions
