| Class | Description |
|---|---|
| Backend |
Orchestrates and configures all backend systems:
The primary backend storage (

| BackendTransaction |
Bundles all storage/index transactions and provides a proxy for some of their
methods for convenience.
|
| EntryList.EmptyList | |
| EntryMetaData.Map | |
| Mutation<E,K> |
Container for collection mutations against a data store.
|
| StoreMetaData.Container |
