ManagedAttributeDescription class

Stores the specifics of database columns in ManagedObjects as indicated by Column.

This class is used internally to manage data models. For specifying these attributes, see Column.

Attributes are the scalar values of a ManagedObject (as opposed to relationship values, which are ManagedRelationshipDescription instances).

Each scalar property ManagedObject object persists is described by an instance of ManagedAttributeDescription. This class adds two properties to ManagedPropertyDescription that are only valid for non-relationship types, isPrimaryKey and defaultValue.
