DVWindowSharedStore class

Constructors

DVWindowSharedStore({DVSharedStoreBackend? backend, DVSharedStoreCipher cipher = const DVNullSharedStoreCipher(), Duration debounce = const Duration(milliseconds: 50), int spillThresholdBytes = 32 * 1024, DVFileStorageAdapter? spillStorage, DVAppKeyStoreSource? appKeys})

Properties

debounce → Duration

A signal changing per frame must not produce a write per frame.

final

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

spillThresholdBytes → int

Values larger than this go to file storage, leaving a pointer behind.

final

Methods

dispose() → Future<void>

evictCache() → void

Drops the in-memory copy so the next read goes to the backend.

flush(String key) → Future<void>

Writes now, bypassing the debounce. Tear-out uses this: the window is about to open and the state has to be there when it reads.

get(String key) → Future<DVJsonValue?>

keys() → Future<List<String>>

namespace(String prefix) → DVSharedStoreNamespace

The handle a package keeps its state in the namespace it claimed with.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

remove(String key) → Future<void>

set(String key, DVJsonValue? value) → Future<void>

Writes value, coalescing rapid writes to the same key.

signal(String key) → ValueListenable<DVJsonValue?>

A live signal for key, updated by this window and by any other.

toString() → String

A string representation of this object.

inherited

watch(String key) → Stream<DVJsonValue?>

Operators

operator ==(Object other) → bool

The equality operator.

inherited

Static Properties

defaultAppKeys ↔ DVAppKeyStoreSource

Where a store made without appKeys finds the application key store.

getter/setter pair

reservedPrefixes → List<String>

Namespaces an application may not touch.

no setter

sealedPrefixes → List<String>

Namespaces written only encrypted under the application key, whatever cipher the store was given, and refused when no key can be had.

no setter

Static Methods

noAppKeys() → Future<DVAppKeyStore?>

A source with no key store: what a store has until one is configured.

releaseNamespace(String prefix) → void

Hands back a prefix claimed with reserveNamespace. The framework's own dv. and workspace. stay reserved.

reserveNamespace(String prefix, {bool sealed = false}) → void

Claims prefix for a package: applications are refused it, as they are refused dv., and the package reaches it through namespace. sealed keeps every value there encrypted under the application key.
