# nlohmann::ordered_json_editable_view

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

```
using ordered_json_editable_view = basic_json_view<ordered_json, true>;
```

This type is a [`basic_json_view`](https://json.nlohmann.me/api/basic_json_view/index.md) of a value of an [`ordered_json_editable_document`](https://json.nlohmann.me/api/ordered_json_editable_document/index.md), the corresponding view for [`ordered_json_view`](https://json.nlohmann.me/api/ordered_json_view/index.md) the way [`json_editable_view`](https://json.nlohmann.me/api/json_editable_view/index.md) is for [`json_view`](https://json.nlohmann.me/api/json_view/index.md).

## Examples

Example

The example below is the same as [`ordered_json_editable_document`'s](https://json.nlohmann.me/api/ordered_json_editable_document/index.md): the views `set` returns see the document's member order preserved on `materialize()`, unlike for a [`json_editable_document`](https://json.nlohmann.me/api/json_editable_document/index.md).

```
#include <iostream>
#include <nlohmann/json_view.hpp>

using ordered_json_editable_document = nlohmann::ordered_json_editable_document;

int main()
{
    // ordered_json_editable_document is basic_json_document<nlohmann::ordered_json, true>
    ordered_json_editable_document doc = ordered_json_editable_document::parse(R"({"z": 1, "a": 2, "m": 3})");
    doc.set(doc.root(), "b", 4); // set() always appends a new member at the end

    // materialize() preserves the document order (with "b" at the end),
    // instead of sorting the keys the way json_editable_document does
    std::cout << doc.root().materialize().dump() << '\n';
}
```

Output:

```
{"z":1,"a":2,"m":3,"b":4}
```
