# <small>nlohmann::</small>json_editable_view
|
|
|
|
<small>Defined in header `<nlohmann/json_view.hpp>`</small>
|
|
|
|
```cpp
|
|
using json_editable_view = basic_json_view<json, true>;
|
|
```
|
|
|
|
This type is a [`basic_json_view`](basic_json_view/index.md) of a value of a
|
|
[`json_editable_document`](json_editable_document.md). It offers the same read-only interface as
|
|
[`json_view`](json_view.md); what is different is what it can be a view *of* -- a value that
|
|
[`set`](basic_json_document/set.md) and [`push_back`](basic_json_document/push_back.md) can change, with every view
|
|
still referring to it seeing the change, see [Edits](basic_json_document/index.md#edits).
|
|
|
|
## Examples
|
|
|
|
??? example
|
|
|
|
The example below is the same as [`json_editable_document`'s](json_editable_document.md): every view read back
|
|
out of the document -- `#!cpp doc.root()` and the views nested under it -- sees the edits made through `set`.
|
|
|
|
```cpp
|
|
--8<-- "examples/json_editable_document.cpp"
|
|
```
|
|
|
|
Output:
|
|
|
|
```json
|
|
--8<-- "examples/json_editable_document.output"
|
|
```
