Examples of WriteNullsProtocol

org.apache.hadoop.hive.serde2.thrift.WriteNullsProtocol
An interface for TProtocols that actually write out nulls - This should be for all those that don't actually use fieldids in the written data like TCTLSeparatedProtocol.

Examples of org.apache.hadoop.hive.serde2.thrift.WriteNullsProtocol

    ListObjectInspector loi = (ListObjectInspector) oi;
    ObjectInspector elementObjectInspector = loi
        .getListElementObjectInspector();
    DynamicSerDeTypeBase mt = getElementType();


    WriteNullsProtocol nullProtocol =
        (oprot instanceof WriteNullsProtocol) ? (WriteNullsProtocol) oprot : null;


    if (o instanceof List) {
      List<?> list = (List<?>) o;
      oprot.writeListBegin(new TList(mt.getType(), list.size()));
      for (Object element : list) {
        if (element == null) {
          assert (nullProtocol != null);
          nullProtocol.writeNull();
        } else {
          mt.serialize(element, elementObjectInspector, oprot);
        }
      }
    } else {
      Object[] list = (Object[]) o;
      oprot.writeListBegin(new TList(mt.getType(), list.length));
