objectbox library

Classes

Admin: ObjectBox Admin allows you to explore the database in a regular web browser.
Backlink: Backlink annotation specifies a link in a reverse direction of another relation.
Box<T>: A Box instance gives you access to objects of a particular type. You get Box instances via Store.box() or Box(Store).
Condition<EntityT>: A Query condition base class.
DebugFlags: Passed as debugFlags when calling Store.new to enable debug options.
Entity: Entity annotation is used on a class to let ObjectBox know it should store it - making the class a "persistable Entity".
HnswFlags: Flags as a part of the HnswIndex configuration.
HnswIndex: See HnswIndex.new.
Id: Annotation Id can be used to specify an entity ID property if it's named anything else then "id" (case insensitive).
IdWithScore: Wraps the ID of a matching object and a score when using Query.findIdsWithScores.
Index: Specifies that the property should be indexed.
ObjectWithScore<T>: Wraps a matching object and a score when using Query.findWithScores.
Order: Groups query order flags.
Property: Use to (optionally) annotate a field to explicitly configure some details about how a field is stored in the database.
PropertyQuery<T>: Property query base.
Query<T>: A repeatable Query returning the latest matching Objects.
QueryBacklinkToMany<Source, Target>
QueryBooleanProperty<EntityT>
QueryBuilder<T>: Query builder allows creating reusable queries.
QueryByteVectorProperty<EntityT>
QueryDateNanoProperty<EntityT>: This wraps QueryIntegerProperty for DateTime properties annotated with @Property(type: PropertyType.dateNano) to avoid having to manually convert to nanoseconds (DateTime.microsecondsSinceEpoch * 1000) when creating query conditions.
QueryDateProperty<EntityT>: This wraps QueryIntegerProperty for DateTime properties to avoid having to manually convert to DateTime.millisecondsSinceEpoch when creating query conditions.
QueryDoubleProperty<EntityT>
QueryDoubleVectorProperty<EntityT>: For double vectors greater and less queries are supported on elements of the vector (e.g. "has element greater").
QueryHnswProperty<EntityT>: Provides extra conditions for float vector properties with an HnswIndex.
QueryIntegerProperty<EntityT>
QueryIntegerVectorProperty<EntityT>: For integer vectors (excluding QueryByteVectorProperty) greater, less and equal are supported on elements of the vector (e.g. "has element greater").
QueryProperty<EntityT, DartType>: The QueryProperty types allow users to build query conditions on a property.
QueryRelationToMany<Source, Target>
QueryRelationToOne<Source, Target>
QueryStringProperty<EntityT>
QueryStringVectorProperty<EntityT>
Store: Represents an ObjectBox database and works together with Box to allow getting and putting.
Sync: ObjectBox Sync makes data available and synchronized across devices, online and offline.
SyncChange: Sync incoming data event.
SyncClient: Sync client is used to connect to an ObjectBox sync server. Use through Sync.
SyncCredentials: Credentials used to authenticate a sync client against a server.
ToMany<EntityT>: A to-many relation of an entity that references multiple objects of a "target" entity EntityT.
ToOne<EntityT>: A to-one relation of an entity that references one object of a "target" entity EntityT.
Transient: Transient annotation marks fields that should not be stored in the database.
Unique: Enforces that the value of a property is unique among all objects in a box before an object can be put.
Version: Wrapper for a semantic version information.

Enums

ConflictStrategy: Used with Unique to specify the conflict resolution strategy.
IndexType: IndexType can be used to change what type ObjectBox uses when indexing a property.
PropertyType: Use with Property.type.
PutMode: Box put (write) mode.
SyncConnectionEvent: Connection state change event.
SyncLoginEvent: Login state change event.
SyncRequestUpdatesMode: Configuration of how SyncClient fetches remote updates from the server.
SyncState: Current state of the SyncClient.
TxMode: Configure transaction mode. Used with Store.runInTransaction().
VectorDistanceType: The vector distance algorithm used by an HnswIndex (vector search).

Extensions

DoublePropertyQuery on PropertyQuery<double>: "Property query" for a double field. Created by Query.property().
IntegerPropertyQuery on PropertyQuery<int>: "Property query" for an integer field. Created by Query.property().

QueryParamBool on QueryParam<bool>: QueryParam for boolean properties
QueryParamBytes on QueryParam<List<int>>: QueryParam for byte vector properties

Exceptions / Errors

DbFileCorruptException: Errors were detected in a database file, e.g. illegal values or structural inconsistencies.
DbFullException: Thrown when applying a transaction (e.g. putting an object) would exceed the maxDBSizeInKB configured when calling Store.new.
DbMaxDataSizeExceededException: Thrown when applying a transaction would exceed the maxDataSizeInKByte configured when calling Store.new.
DbMaxReadersExceededException: Thrown when the maximum amount of readers (read transactions) was exceeded.
DbPagesCorruptException: Errors related to pages were detected in a database file, e.g. bad page refs outside of the file.
DbShutdownException: Thrown when an error occurred that requires the store to be closed.
NonUniqueResultException: Thrown if Query.findUnique() is called, but the query matches more than one object.
NumericOverflowException: Thrown if a property query aggregate function (e.g. sum()) can not compute a result due to a number type overflowing.
ObjectBoxException: ObjectBox database exception.
SchemaException: Thrown when there is an error with the data schema (data model).
StorageException: ObjectBox database exception with an OBX_ERROR code.
UniqueViolationException: A unique constraint would have been violated by this database operation.
