HiveCrdt class
Properties
- canonicalTime ↔ Hlc
-
Represents the latest logical time seen in the stored data.
getter/setter pairinherited
- hashCode → int
-
The hash code for this object.
no setterinherited
- isEmpty → bool
-
Whether this dataset is empty.
no setter
- isNotEmpty → bool
-
Whether this dataset has at least one record.
no setter
- nodeId → String
-
Get this CRDT's node id
no setterinherited
-
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 setterinherited
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
-
tables
→ Set<
String> -
Names of all tables contained in this dataset.

Methods
-
close(
) → Future< void> - Closes all tables
-
delete(
) → Future< void> - Deletes all tables from disk
-
get(
String table, String key) → dynamic -
Get a value from the local dataset.
inherited
-
getChangeset(
{Iterable< String> ? onlyTables, String? onlyNodeId, String? exceptNodeId, Hlc? modifiedOn, Hlc? modifiedAfter}) → CrdtChangeset -
Get a
Changesetusing the providedchangesetQueries.inherited -
getLastModified(
{String? onlyNodeId, String? exceptNodeId}) → 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.
inherited
-
getMap(
String table) → Map< String, dynamic> -
Get a table map from the local dataset.
inherited
-
getRecord(
String table, String key) → Record? -
getRecords(
String table) → Map< String, Record> -
merge(
CrdtChangeset changeset) → Future< void> -
Merge
changesetwith the local dataset.inherited -
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.
inherited
-
purge(
) → Future< void> - Deletes all data from every table
-
put(
String table, String key, dynamic value, [bool isDeleted = false]) → Future< void> -
Insert a single value into this dataset.
inherited
-
putAll(
Map< String, Map< dataset, [bool isDeleted = false]) → Future<String, dynamic> >void> -
Insert multiple values into this dataset.
inherited
-
putRecords(
Map< String, Map< dataset) → Future<String, Record> >void> -
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.
inherited
-
watch(
String table, {String? key}) → Stream< WatchEvent> -
Returns a stream of changes.
Use the optional
keyparameter to filter events or leave it empty to get all changes.
Operators
-
operator ==(
Object other) → bool -
The equality operator.
