Examples of nexj.core.persistence.OID

nexj.core.persistence.OID
Object Identifier - a value object used to match the copies of an object instance across process boundaries. Usually, they contain the primary key and can be compared based on its values, including for total ordering.

            Metaclass metaclass = (Metaclass)classObj;
            Instance instance;

               }
               else if (oidArray instanceof OID)
