Instance Method Details

#fetch(selector_store) ⇒ FetchResult

Retrieves the initial data set for the data source.

If the LaunchDarkly server has instructed the SDK to fall back to the FDv1 protocol, the returned FetchResult#fallback_to_fdv1 is true. The wrapped result may still carry a successful Basis when the directive accompanied a valid payload, in which case callers should apply the payload before switching protocols.
