Example

|

The example shows how `get_allocator()` is used to created `json` values.
|
|
|
|
```
|
|
#include <iostream>
|
|
#include <nlohmann/json.hpp>
|
|
|
|
using json = nlohmann::json;
|
|
|
|
int main()
|
|
{
|
|
auto alloc = json::get_allocator();
|
|
using traits_t = std::allocator_traits<decltype(alloc)>;
|
|
|
|
json* j = traits_t::allocate(alloc, 1);
|
|
traits_t::construct(alloc, j, "Hello, world!");
|
|
|
|
std::cout << *j << std::endl;
|
|
|
|
traits_t::destroy(alloc, j);
|
|
traits_t::deallocate(alloc, j, 1);
|
|
}
|
|
```
|
|
|
|
Output:
|
|
|
|
```
|
|
"Hello, world!"
|
|
```
