AtPersistenceBundle class abstract

All the per-atSign persistence resources an at_server needs, produced by an AtPersistenceFactory.

The bundle exposes three top-level resources, each of which implements Compactable:

• keyValueStore — the main key-value store. Its internal commit log (server-side; null on client-side) is reachable via AtKeyValueStore.commitLog.
• accessLog — optional audit trail (server-side only).
• notificationKeystore — optional notification queue (server-side only).

Server-shaped consumers (full atSecondary) opt into all capabilities; client-shaped consumers (e.g. at_client_sdk's local cache) opt into the keystore only.

Implementers

• DualWriteBundle
• HiveAtPersistenceBundle
• SqliteAtPersistenceBundle

Constructors

AtPersistenceBundle()

Properties

accessLog → AtAccessLog?

The access log used for stats and security audit. null when AtPersistenceConfig.enableAccessLog is false (typical for client-only consumers).

no setter

atSign → String

The atSign this bundle owns.

no setter

backendId → AtPersistenceBackendId

Identifies which backend produced this bundle.

no setter

hashCode → int

The hash code for this object.

no setter, inherited

isClosed → bool

true after close has been called (whether directly on the bundle or via the owning factory). Once closed, methods on the bundle are undefined; the producing factory's bundleFor returns null and AtPersistenceFactory.initialize rebuilds.

no setter

keyValueStore → AtKeyValueStore<String, AtData, AtMetaData?>

The keystore for client data (target of update / lookup). Its commit log is accessible as keyValueStore.commitLog — non-null on server bundles, null on client bundles.

no setter

notificationKeystore → AtNotificationKeystore?

The notification keystore. null when AtPersistenceConfig.enableNotificationKeystore is false.

no setter

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

clear() → Future<void>

Drop all data from this bundle's stores while keeping the underlying connections (Hive boxes etc.) open. Idempotent. Intended for cheap per-test isolation.

close() → Future<void>

Close all underlying resources. Idempotent.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
