Generated using TypeDoc
Loki/Sylvie encrypted persistence adapter class for indexedDb. This class fulfills abstract adapter interface which can be applied to other storage methods. Utilizes the included SylvieCatalog app/key/value database for actual database persistence. IndexedDb storage is provided per-domain, so we implement app/key/value database to allow separate contexts for separate apps within a domain.
