AtClientStorageBase class abstract

The claim rules every AtClientStorage shares; a backend supplies location, openBackend, closeBackend and clearData.

Implemented types

Implementers

Constructors

closedByClient → bool: Whether the client that attaches to this storage closes it on AtClient.stop.
final
hashCode → int: The hash code for this object.
no setterinherited
isAttached → bool: no setter
keyStore → AtKeyValueStore<String, AtData, AtMetaData?>: no setterinherited
location → String: The store this points at, in a form two storages over the same records report identically — everything that decides which records they resolve to, not only where the files sit: a backend keyed by atSign within a directory includes the atSign, since two atSigns there share nothing. An instance whose data is private to itself reports a token unique to it.
no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
syncQueue → AtSyncQueue: no setterinherited

attach(AtClient owner) → Future<void>: Claims this storage for owner.
override
clear() → Future<void>: Empties keystore and queue and forgets the last principal. Idempotent.
override
clearData() → Future<void>: Empties keystore and queue.
close() → Future<void>: Closes the backend. Idempotent.
override
closeBackend() → Future<void>: Closes the backend. Called at most once, by close.
detach(AtClient owner) → Future<void>: Drops owner's claim, keeping the backend open.
override
forgetPrincipal() → Future<void>: Forgets which principal last held this storage, keeping the data.
override
isHeldBy(AtClient client) → bool: Whether client is the one currently holding this storage.
override
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
openBackend() → Future<void>: Opens the backend. Idempotent.
toString() → String: A string representation of this object.
inherited

principalOf(AtClient client) → String: The (atSign, enrollmentId) a client acts as.
