```cpp

using initializer_list_t = std::initializer_list<detail::json_ref<basic_json>>;
|

```
|
||||
|
||||
The type used for the initializer-list [constructor](basic_json.md) (overload 5) and for functions
|
||||
such as [`operator=`](operator=.md) that accept a braced-init-list of JSON values. Each element wraps a
|
||||
`basic_json` value or something convertible to one, deferring the decision of whether the list should be
|
||||
parsed as a JSON array or a JSON object to the constructor itself.

|
||||
|

The comparator used to determine key equality when looking up elements. Unlike `std::map`, `ordered_map`
|

uses linear search with `key_compare` rather than an ordering relation, since element order reflects
|
||||
insertion order rather than key order.
|

|

Since C++14, the transparent `#!cpp std::equal_to<>` is used, which enables heterogeneous lookup (e.g.

looking up by a `#!cpp const char*` key without constructing a temporary `Key`).

# <small>nlohmann::ordered_map::</small>ordered_map
|
||||
|
||||
```cpp
|
||||
// (1)
|
||||
ordered_map() noexcept(noexcept(Container()));
|
||||
|
||||
// (2)
|
||||
explicit ordered_map(const Allocator& alloc) noexcept(noexcept(Container(alloc)));
|
||||
|
||||
// (3)
|
||||
template <class It>
|
||||
ordered_map(It first, It last, const Allocator& alloc = Allocator());
|
||||
|
||||
// (4)
|
||||
ordered_map(std::initializer_list<value_type> init, const Allocator& alloc = Allocator());
|

ordered_map(ordered_map&&) noexcept(std::is_nothrow_move_constructible<Container>::value) = default;
|
||||
```
|
||||
|
||||
1. Default constructor. Creates an empty `ordered_map`.
|
||||
2. Creates an empty `ordered_map` using the given allocator.
|
||||
3. Creates an `ordered_map` from the elements in range `[first, last)`, inserted in iteration order.
|
||||
4. Creates an `ordered_map` from an initializer list of key/value pairs, inserted in list order.
|
||||
5. Copy constructor.
|
||||
6. Move constructor.
|
||||
|
||||
These constructors are declared explicitly (rather than inherited via `#!cpp using Container::Container`)
|
||||
because older compilers (GCC <= 5.5, Xcode <= 9.4) do not handle the inherited constructors correctly.
|
||||
|
||||
## Template parameters
|
||||
|
||||
`It`
|
||||
: an input iterator type
|
||||
|
||||
## Parameters
|
||||
|
||||
`alloc` (in)
|
||||
: allocator to use for the underlying container
|
||||
|
||||
`first` (in)
|
||||
: iterator to the first element to insert
|
||||
|
||||
`last` (in)
|
||||
: iterator one past the last element to insert
|
||||
|
||||
`init` (in)
|
||||
: initializer list of key/value pairs to insert
|
||||
|
||||
## Complexity
|
||||
|
||||
1. Constant.
|
||||
2. Constant.
|
||||
3. Linear in the distance between `first` and `last`.
|
||||
4. Linear in the size of `init`.
|
||||
5. Linear in the size of `other`.
|
||||
6. Constant.

`#!cpp std::pair` and `#!cpp std::tuple` are also supported, converting positionally to and from a JSON array:

```cpp

json j = {1.0, "hello", 42};

!!! info "Extracting references into a tuple"
|
||||
|
||||
A tuple type may also hold references (e.g. `#!cpp std::tuple<double&, std::string&>`) to avoid copying: `get`
|
||||
then returns a tuple of references pointing directly at the elements stored inside the `basic_json` array,
|
||||
rather than a tuple of copies:

|
||||
```cpp

json j = {1.0, "hello"};

std::get<1>(refs) = "world"; // modifies j[1] in place
|
||||
```
|
||||
|
||||
A referenced type must be one the library actually stores (or an arithmetic type it can convert to/from);
|
||||
otherwise this is a compile error.
|
||||
|
||||
## Implicit conversions
|
||||
|
||||
By default, a JSON value implicitly converts to a compatible C++ type, so the explicit `get` call can often be omitted:

!!! info "Constructing from a C++20 range view"
|
||||
|
||||
A `json` array can also be constructed directly from a C++20 range view (`std::ranges::view`), such as the result
|
||||
of `std::views::filter` or `std::views::transform` -- no intermediate container is needed:
|
||||
|
||||
```cpp
|
||||
std::vector<int> nums{1, 2, 37, 42, 21};
|
||||
auto filtered = nums | std::views::filter([](int i) { return i > 10; });
|
||||
json j(filtered); // [37,42,21]
|
||||
```
|
||||
|
||||
This requires [`JSON_HAS_RANGES`](../api/macros/json_has_ranges.md) to be enabled and is unavailable on MinGW due
|
||||
to incomplete C++20 ranges support there.
|
||||
|
||||
## Your own types

The conversions above are built in for standard types. To make the same syntax work for **your own** types, provide
