Crdt class abstract mixin

Implementers

• HiveCrdt

Constructors

Crdt()

Properties

canonicalTime ↔ Hlc

Represents the latest logical time seen in the stored data.

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

nodeId → String

Get this CRDT's node id

no setter

onTablesChanged → Stream<({Hlc hlc, Iterable<String> tables})>

Emits a list of the tables affected by changes in the database and the timestamp at which they happened. Useful for guaranteeing atomic merges across multiple tables.

no setter

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

getChangeset({Iterable<String>? onlyTables, String? onlyNodeId, String? exceptNodeId, Hlc? modifiedOn, Hlc? modifiedAfter}) → FutureOr<CrdtChangeset>

Get a Changeset using the provided changesetQueries.

getLastModified({String? onlyNodeId, String? exceptNodeId}) → FutureOr<Hlc>

Returns the last modified timestamp, optionally filtering for or against a specific node id. Useful to get "modified since" timestamps for synchronization. Returns Hlc.zero if no timestamp is found.

merge(CrdtChangeset changeset) → FutureOr<void>

Merge changeset with the local dataset.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

onDatasetChanged(Iterable<String> affectedTables, Hlc hlc) → void

Notifies listeners and updates the canonical time.

toString() → String

A string representation of this object.

inherited

validateChangeset(CrdtChangeset changeset) → Hlc

Checks if changeset is valid. This method is intended for implementations and shouldn't generally be called from outside.

Operators

operator ==(Object other) → bool

The equality operator.
