[lworld] Support of null markers for nullable flat fields

    XMLWordPrintable

Details

    Description

      The first step to be able to flatten value fields within scope of JEP 401 is to have a null marker associated with such fields, to indicate if the current value of the value is the null reference or the flat representation embedded in the container.
      Those null markers must be included in the object layout, and field accesses must be adjusted to either check or update those null markers.
