ManagedDataModel class Null safety
Instances of this class contain descriptions and metadata for mapping ManagedObjects to database rows.
An instance of this type must be used to initialize a ManagedContext, and so are required to use Querys.
The ManagedDataModel.fromCurrentMirrorSystem constructor will reflect on an application's code and find all subclasses of ManagedObject, building a ManagedEntity for each.
Most applications do not need to access instances of this type.
Constructors
-
ManagedDataModel(List<
Type> instanceTypes) - Creates an instance of ManagedDataModel from a list of types that extend ManagedObject. It is preferable to use ManagedDataModel.fromCurrentMirrorSystem over this method.
- ManagedDataModel.fromCurrentMirrorSystem()
- Creates an instance of a ManagedDataModel from all subclasses of ManagedObject in all libraries visible to the calling library.
