      protected abstract boolean shouldConvert(com.yahoo.document.datatypes.FieldValue value)
      Returns whether the given FieldValue should be converted. If this method returns false, the converter will proceed to traverse the value itself to see if its internal can be converted.

      Returns:
      true to convert, false to traverse

      Returns:
      the value to replace the old
