StorageInstanceManager

Unified manager for opening and caching storage instances (Dataset, KeyValueStore, RequestQueue).

A single instance manages all storage types. Instances are cached by (storageClass, id/name/alias, backendCacheKey) so the same storage is never opened twice.

The manager itself does not resolve identifiers — callers pass explicit id, name, or alias (at most one), and a pre-bound backendOpener promise. When none of id, name, alias are provided, the manager automatically assigns a reserved default alias.

Constructors

constructor

• new StorageInstanceManager(): StorageInstanceManager

• Returns StorageInstanceManager

Methods

clearCache

• clearCache(): void

• Clear the entire cache. Also calls clearCache() on any cached KeyValueStore instances (duck-typed to avoid importing KeyValueStore and circular dependencies). Called during service locator reset.

  ---

  Returns void

openStorage

• openStorage<TStorage>(cls, __namedParameters): Promise<TStorage>

• Open (or retrieve from cache) a storage instance.

  ---

  Parameters

  • cls: Constructor<TStorage>

    The storage class constructor (e.g. Dataset, KeyValueStore, RequestQueue).

  • __namedParameters: ExplicitStorageIdentifier | DefaultStorageIdentifier & { backendCacheKey: string; backendOpener: () => Promise<DatasetBackend<Dictionary> | KeyValueStoreBackend | RequestQueueBackend> }

  Returns Promise<TStorage>

removeFromCache

• removeFromCache(instance): void

• Remove a storage instance from the cache (called from storage.drop()).

  ---

  Parameters

  • instance: IStorage

  Returns void
