        vector = BasicTypeHelper.getNewVector(field, allocator);
        // returned vector must have the same field
        assert field.equals(vector.getField());
        getField().addChild(field);
        created = true;
    }
    final TypeProtos.MajorType actual = vector.getField().getType();
