DataScopeHolder<Container extends DataScopeContainer<Data>, Data extends Object> class abstract

Simple holder for creating BaseDataScopeHolder.

Here is an example:

class DataScopeHolder extends DataScopeHolder<DataScopeContainer, Data> {
   @override
   DataScopeContainer createContainer(Data data) => DataScopeContainer(data: data);
}

You also have to declare DataScopeContainer, see BaseScopeContainer.

Working with scope:

await dataScopeHolder.create(SomeData());
// Scope exists here

await dataScopeHolder.drop();
// Scope does not exist here

If you need to differentiate BaseScopeContainer and it's abstract interface then you better use BaseDataScopeHolder directly.

Methods

create(Data data) → Future<void>
inherited
createContainer(Data data) → Container
inherited
drop() → Future<void>
Dispose scope. Scope becomes unavailable.
inherited
init(Container scope) → Future<void>
Initialize scope. Scope becomes available and everyone can start working with it via BaseScopeHolder.
inherited
listen(StateListener<Container> listener, {bool emitImmediately = false}) → RemoveStateListener
Subscribes to the state.
inherited
listenState(ScopeStateListener<Container> listener, {bool emitImmediately = false}) → RemoveStateListener
Subscribes to the state.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.
