The INullable interface is used to determine whether or not an instance of an EntityObject allows having a NULL value.
public interface INullable
Remarks
Some ModelElements (e.g. ModelProperty or Relation) can be marked as nullable. The metainformation about if a Relation or a ModelProperty can be null determines if a relation or property on an EntityObject can be null or not. The information if a property or relation can be null is also persisted in the metainformation of the underlying database.
