# <small>nlohmann::</small>ordered_json_editable_document

<small>Defined in header `<nlohmann/json_view.hpp>`</small>

```cpp
using ordered_json_editable_document = basic_json_document<ordered_json, true>;
```

This type is an **editable** [`basic_json_document`](basic_json_document/index.md) of the
[`ordered_json`](ordered_json.md) specialization: [`set`](basic_json_document/set.md) and
[`push_back`](basic_json_document/push_back.md) change values after parsing, as for
[`json_editable_document`](json_editable_document.md), and
[`materialize()`](basic_json_view/materialize.md) preserves the document order of object members -- including
members [`set`](basic_json_document/set.md) added -- instead of sorting them like
[`json_editable_document`](json_editable_document.md) does.

## Examples

??? example

    The example below edits a document with `set`, then shows that `materialize()` keeps the member order of the
    source text (with the new member at the end) for `ordered_json_editable_document`, where it would sort the
    members alphabetically for [`json_editable_document`](json_editable_document.md).

    ```cpp
    --8<-- "examples/ordered_json_editable_document.cpp"
    ```

    Output:

    ```json
    --8<-- "examples/ordered_json_editable_document.output"
    ```
