Collection<T> class abstract

Abstract baseclass for Collections of a specific type. DataStore subclasses must implement this to return a Collection which knows how to query and update a given collection/table in the datastore corresponding to a type.

Constructors

Collection(ClassInfo<T> classInfo)

Properties

classInfo → ClassInfo<T>

Collection base class hols the classInfo, which is used to lookup static information about the type such as toJson/fromJson methods.

final

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

Methods

byId(ObjectId id) → Future<T?>

Subclasses must implement this to return a single object by id.

create(T object) → Future<T>

Subclasses must implement this to create a single object in the datastore.

createMany(List<T> objects) → Future<List<T>>

Subclasses must implement this to create multiple objects in the datastore.

find(SelectorBuilder selector) → Stream<T>

Subclasses must implement this to return a stream of objects found with the given selector.

findOne(SelectorBuilder selector) → Future<T?>

Subclasses must implement this to return a single object found with the given selector.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

update(ObjectId id, T update(T object)) → Future<void>

Subclasses must implement this to update a single object by id. The update function is passed the current object and should return the updated object.

watchAdditions() → Stream<T>

Subclasses must implement this to return a stream of objects as they are added to the collection.

Operators

operator ==(Object other) → bool

The equality operator.
