ManagedSet<InstanceType extends ManagedObject> class Null safety

Instances of this type contain zero or more instances of ManagedObject and represent has-many relationships.

'Has many' relationship properties in ManagedObjects are represented by this type. ManagedSets properties may only be declared in the persistent type of a ManagedObject. Example usage:

   class User extends ManagedObject<_User> implements _User {}
   class _User {
      ...
      ManagedSet<Post> posts;
   }

   class Post extends ManagedObject<_Post> implements _Post {}
   class _Post {
     ...
     @Relate(#posts)
     User user;
   }
