MemoryCacheProvider<CModel extends SqliteModel> class
Query models by SQLite primary key, sparing a more expensive on-disk lookup.
MemoryCacheProvider does not have a type argument due to a build_runner exception: https://github.com/dart-lang/sdk/issues/38309
Constructors
-
MemoryCacheProvider([List<
Type> managedModelTypes = const <Type>[]]) -
It is strongly recommended to use this provider with smaller, frequently-accessed
and shared
TModel
s.
Properties
- hashCode → int
-
The hash code for this object.
no setterinherited
- logger → Logger
-
final
-
managedModelTypes
→ List<
Type> -
The only model classes this instance should track.
As storing objects in memory can be costly elsewhere in the app, models should be
judiciously added to this property.
final
-
managedObjects
↔ Map<
Type, Map< int, CModel> > -
A complete hash table of the
getter/setter pair
-
modelDictionary
→ ModelDictionary<
Model, Adapter< Model> > -
Only present to conform to the
Provider
spec.final - runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
Methods
-
canFind<
TModel extends CModel> ([Query? query]) → bool - Whether the results of this provider are worth evaluating.
-
delete<
TModel extends CModel> (TModel instance, {Query? query, ModelRepository< CModel> ? repository}) → bool - Remove a model instance
-
exists<
T extends TModel> ({Query? query, ModelRepository< CModel> ? repository}) → dynamic -
Whether a model instance is present.
null
is returned when existence is unknown. The model instance is not hydrated in the function output; abool
variant (e.g.List<bool>
,Map<TModel, bool>
) should be returned.inherited -
get<
TModel extends CModel> ({Query? query, ModelRepository< CModel> ? repository}) → List<TModel> ? -
Query for raw data and construct it with an
Adapter
-
hydrate<
TModel extends CModel> (List< TModel> models) → List<TModel> -
Replenish managedObjects with new data.
Any one of the
models
with a null.primaryKey
will not be inserted. This avoids unexpected null collisions. -
manages(
Type type) → bool -
Is the
type
cached by this provider? -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
reset(
) → void - Destructively wipes all tracked instances. Irreversible.
-
toString(
) → String -
A string representation of this object.
inherited
-
upsert<
TModel extends CModel> (TModel instance, {Query? query, ModelRepository< CModel> ? repository}) → TModel? - Insert or update a model instance
Operators
-
operator ==(
Object other) → bool -
The equality operator.
