Niels Lohmann 589c29d69b Keep the unit-comparison.cpp types out of the anonymous namespace
GCC reports a basic_json specialized with a type of an anonymous
namespace in a file #include-d into a batch (-Wsubobject-linkage), so
only the helper functions go into the anonymous namespace.

Niels Lohmann 80fd9c0fb4 Build files that suppress -Wnoexcept on their own
unit-udt.cpp suppresses GCC's -Wnoexcept around its include of the
library just like unit-noexcept.cpp, so instead of listing the files,
leave every file that suppresses the warning out of the batches.

Move the helpers of unit-comparison.cpp into an anonymous namespace
inside unit_comparison_detail, as clang-tidy's misc-use-internal-linkage
wants internal linkage for them.

Niels Lohmann 169f1fcb2d Fix the Ubuntu CI failures of the unity test build
- build unit-noexcept.cpp on its own: it suppresses GCC's -Wnoexcept
  around its include of the library, which has no effect once another
  file of the batch included the library first
- unit-comparison.cpp: make make_unordered_object inline
  (-Wmissing-prototypes in a named namespace) and replace the
  using-directive by using-declarations, as Clang reports a
  using-directive in an #include-d file (-Wheader-hygiene)
- unit-json_pointer-cpp20.cpp: include <compare> only with
  JSON_HAS_THREE_WAY_COMPARISON; GCC 9 and Clang 9 accept C++20 but
  have no <compare>

Niels Lohmann 769c5cde57 Fix CI failures of the unity test build
- keep JSON_DISABLE_ENUM_SERIALIZATION and
  JSON_DISABLE_TUPLE_REFERENCE_CONVERSION defined with
  JSON_TEST_KEEP_MACROS, so that every file of a batch sees them, not only
  the first one
- mark JSON_TESTS_PRIVATE in the generated batch file as used, as GCC and
  Clang report an unused definition when the first file defines it again
  (-Wunused-macros)
- suppress bugprone-suspicious-include for the #include-d .cpp files
- avoid local json aliases and variables that hide a global json of
  another file in the same batch (MSVC C4459)

Niels Lohmann 993e37e7ec Reduce test compile times (spike)
Two changes roughly halve the CPU time needed to build the unit tests
(clang 21: ~300 s -> ~150 s, GCC 16: ~750-820 s -> ~395-420 s, Debug):

- Move the C++14/17/20-dependent tests into separate
  unit-<name>-cpp<N>.cpp files. A test file is built for every standard
  whose JSON_HAS_CPP_<N> macro it mentions, so far whole large files were
  rebuilt for C++14/17/20 because of a few #ifdef sections. The main files
  are now built for C++11 only; the ci_test_*_cxx<N> jobs still build
  every file for every standard.

- Add the CMake option JSON_TestUnityBuild (ON by default, OFF with
  MinGW): compatible test files are compiled in batches as one
  translation unit so they share the template instantiations of the
  library. Each file keeps its own CTest test, which runs the batch
  executable filtered to that file's test cases. The binary-format tests
  form an explicit group; the rest is batched by JSON_TestUnityBatchSize.

Fix the name clashes that merging files exposed, document the rules for
test files in tests/README.md, and point CONTRIBUTING.md to it.

### Zero-copy views
Header `<nlohmann/json_view.hpp>` adds `json_document`/`json_view`, a read-only, non-owning way to look at a parsed
JSON text: parsing builds a flat index (16 bytes per value) instead of a tree, strings and numbers stay in the source
text, and `materialize()` builds a `json` value for a subtree only when you actually need one. See
[Zero-copy JSON views](https://json.nlohmann.me/features/json_view/) for the details, including which inputs are
borrowed and which are copied.

Don't use multiline raw strings directly in macros with this compiler.
- For GCC running on MinGW or Android, the error `'to_string' is not a member of 'std'` (or similarly, for `strtod` or `strtof`) may occur. Note this is not an issue with the code, but rather with the compiler or C++ standard library itself: use a recent toolchain (for Android, a current [NDK](https://developer.android.com/ndk) with the LLVM C++ library `APP_STL := c++_shared`, and for MinGW, a distribution with a complete C++11 standard library). See [this discussion](https://github.com/nlohmann/json/issues/136) for MinGW and [this discussion](https://github.com/nlohmann/json/issues/219) for the old Android NDK using `APP_STL := gnustl_static`. - Android defaults to using very old compilers and C++ libraries. To fix this, add the following to your `Application.mk`. This will switch to the LLVM C++ library, the Clang compiler, and enable C++11 and other features disabled by default.
```makefile
APP_STL := c++_shared
NDK_TOOLCHAIN_VERSION := clang3.6
APP_CPPFLAGS += -frtti -fexceptions
```
The code compiles successfully with [Android NDK](https://developer.android.com/ndk/index.html?hl=ml), Revision 9 - 11 (and possibly later) and [CrystaX's Android NDK](https://www.crystax.net/en/android/ndk) version 10.
- For GCC running on MinGW or Android SDK, the error `'to_string' is not a member of 'std'` (or similarly, for `strtod` or `strtof`) may occur. Note this is not an issue with the code, but rather with the compiler itself. On Android, see above to build with a newer environment. For MinGW, please refer to [this site](https://tehsausage.com/mingw-to-string) and [this discussion](https://github.com/nlohmann/json/issues/136) for information on how to fix this bug. For Android NDK using `APP_STL := gnustl_static`, please refer to [this discussion](https://github.com/nlohmann/json/issues/219).

#
# Like calling json_test_add_test_for(<file> MAIN <main> ...) for each of the

# and each batch is built as a single executable
#
# test-unity-<pool><index>_cpp<version_number>
#
# whose generated source file #include-s the files of the batch (so they share
# the template instantiations of the library). The tests are still named
# test-foo_cpp<version_number>, one per file, but run the batch executable with
# a doctest filter that selects the test cases of that file only.
#
# Files are only batched with files that agree on the macros defined before
# the library is included: files that define at most JSON_TESTS_PRIVATE (or
# macros derived from global compile definitions) form the pools "plain" and
# "private". All other files are added with json_test_add_test_for() as usual,
# as are files with test-specific build settings (see
# json_test_set_test_options()) and the files listed in the explicit
# exclusion list below.
# Each <group> names a list variable json_test_unity_group_<group> of test file
# stems (file names without "unit-" and ".cpp"). The batchable files of a group
# are compiled together (regardless of BATCH_SIZE) as one executable
#
# test-unity-<group>_cpp<version_number>
#
# so that related tests, which instantiate the same templates, share one
# translation unit. A group may mix the pools "plain" and "private"; if any of
# its files needs JSON_TESTS_PRIVATE, the whole group is built with it. Files
# that cannot be batched stay standalone even if they are listed in a group.
# Files in no group are batched by BATCH_SIZE as described above.
# <files> in VARIANT_FILES are also built standalone with other settings, so
# they are not marked as header-only sources of the batch.

# <small>nlohmann::basic_json_document::</small>accept
```cpp
template<typename InputType>
static bool accept(InputType&& input,
const bool ignore_comments = false,
const bool ignore_trailing_commas = false);
```
Checks whether the input is valid JSON, accepting and rejecting exactly what
[`BasicJsonType::accept()`](../basic_json/accept.md) does, with the same options. Unlike [`parse()`](parse.md), this
function never throws an exception for invalid input, and the returned `#!cpp bool` is the only result -- no document
is returned.
## Template parameters
`InputType`
: A compatible input; see [`parse`](parse.md#template-parameters).
## Parameters
`input` (in)
: Input to check.
`ignore_comments` (in)
: whether comments should be ignored and treated like whitespace (`#!cpp true`) or yield a parse error
(`#!cpp false`); (optional, `#!cpp false` by default)
`ignore_trailing_commas` (in)
: whether trailing commas in arrays or objects should be ignored and treated like whitespace (`#!cpp true`) or
yield a parse error (`#!cpp false`); (optional, `#!cpp false` by default)
## Return value
Whether the input is valid JSON.
## Exception safety
Strong guarantee: this function itself never throws for an invalid input; it can only throw what allocating the
input's own copy (for inputs that are always read into a buffer) throws.
## Complexity
Linear in the length of the input.
## Notes
An integer argument that is not a `#!cpp bool` where the flags are expected, such as `#!cpp accept(ptr, len)`, does not
compile; see [`parse`](parse.md#notes).

1. Creates an empty (discarded) document: [`root()`](root.md) returns a discarded view, and
[`is_discarded()`](is_discarded.md) is `#!cpp true`.
2. Move constructor. Takes over `other`'s index and, if owned, its text; `other` is left as an empty document. Views
taken from `other` before the move remain valid, because the index is heap-allocated independently of the
`basic_json_document` object.
3. `basic_json_document` is move-only. Copying is disabled because it would either duplicate a potentially large index
and text, or leave two documents claiming to borrow the same buffer.

```
Only an **editable** document (`#!cpp Editable == true`, e.g. [`json_editable_document`](../json_editable_document.md))
has `erase`; calling it on a read-only `basic_json_document` fails to compile (`#!cpp static_assert`).
1. Removes every member of `object` whose key is `key` (see [Notes](#notes) on duplicate keys) and returns how many
were removed; `#!cpp 0` if `object` has no member with this key.
2. Removes the element at index `idx` of `array`, which must already exist (`#!cpp idx < array.size()`).
3. Removes the value the JSON pointer `ptr` refers to, relative to [`root()`](root.md), and returns how many values
were removed: the *parent* of the target must already exist, and the target itself is removed as in 1. (an object
member; `#!cpp 0` or more) or 2. (an array element; always `#!cpp 1`). `ptr` must not be empty -- [`root()`](root.md)
itself cannot be erased.
## Template parameters
`I`
: an integral type other than `#!cpp bool`, deduced (overloads taking a `#!cpp bool` or a non-integral type for
`idx` do not participate in overload resolution).
## Parameters
`object` (in)
: the object to remove a member of
`array` (in)
: the array to remove an element of
`key` (in)
: the key of the member(s) to remove
`idx` (in)
: the index of the element to remove; a negative value throws (see [Exceptions](#exceptions))
`ptr` (in)
: a JSON pointer to the value to remove, relative to `root()`
## Return value
1. the number of removed members (`#!cpp 0` if `object` had none with this `key`)
2. (nothing)
3. the number of removed values (`#!cpp 0` or more for an object member, always `#!cpp 1` for an array element)
## Exceptions
1. Throws [`type_error.307`](../../home/exceptions.md#jsonexceptiontype_error307) if `object` is not an object -- the
same message [`BasicJsonType::erase`](../basic_json/erase.md) throws for the same type.
2. Throws `type_error.307` if `array` is not an array. Throws
[`out_of_range.401`](../../home/exceptions.md#jsonexceptionout_of_range401) if `idx` is negative, or if
`#!cpp idx >= array.size()`.
3. Throws [`out_of_range.405`](../../home/exceptions.md#jsonexceptionout_of_range405) ("JSON pointer has no parent")
if `ptr` is empty. Throws what [`at`](../basic_json_view/at.md) throws (overload 3) for resolving `ptr`'s parent.
For the last reference token itself: if the parent is an array, throws what 2. throws for an index that is out of
range, or, for a token that is not a valid array index,
[`parse_error.106`](../../home/exceptions.md#jsonexceptionparse_error106) (a leading `#!cpp '0'`),
[`parse_error.109`](../../home/exceptions.md#jsonexceptionparse_error109) (not a number),
[`out_of_range.410`](../../home/exceptions.md#jsonexceptionout_of_range410) (too large for `size_type`), or
[`out_of_range.404`](../../home/exceptions.md#jsonexceptionout_of_range404) (an empty token); otherwise (an
object, or a primitive value the pointer's parent resolves to) throws what 1. throws.
Every overload also throws [`invalid_iterator.202`](../../home/exceptions.md#jsonexceptioninvalid_iterator202) ("view
does not belong to this document") if `object`/`array` is a [discarded](../basic_json_view/is_discarded.md) view or a
view of a *different* document (overloads 1-2 only; overload 3 always starts from this document's own
[`root()`](root.md)).
## Complexity
1. Linear in the number of members of `object`.
2. Linear in the number of elements of `array` at or after `idx` (they move one slot over).
3. Linear in the number of reference tokens of `ptr` and, for each token, in the number of members of the object at
that level or the index into the array (as [`at`](../basic_json_view/at.md)), plus the complexity of 1. or 2. for
the last token.
## Notes
!!! info "Duplicate keys"
Overload 1. removes *every* member with `key`, not just the first -- unlike [`set`](set.md), which assigns the
first occurrence and drops the rest. This is why it returns a count rather than a single view: there may be
more than one member removed, or none.
Like [`set`](set.md) and [`push_back`](push_back.md), `erase` never moves an element's *value*: a view still
referring to a removed member or element keeps showing what it last held (see [Edits](index.md#edits)) -- it just no
longer appears when `array`/`object` is read, dumped, or iterated. Removing an element of `array` (2.) does shift the
*links* to the elements after it, the same way `insert`, `set`, or `push_back` on the same array would; any iterator
already taken over `array`/`object` is invalidated by an erase, since it was walking the old layout.
## Examples
??? example
The example below drops a deprecated field and a decommissioned entry from a configuration document -- using all
three overloads -- and shows what stays intact that would not with a plain `json`/`ordered_json` value: the order
of the fields around the ones removed, and the exact spelling of a number that was never touched.

# <small>nlohmann::</small>basic_json_document
<small>Defined in header `<nlohmann/json_view.hpp>`</small>
```cpp
template<typename BasicJsonType, bool Editable = false>
class basic_json_document;
```
A parsed JSON text, held as a flat index of its values
([16 bytes per value](../../home/architecture.md#node-index-of-json-views)) instead of a tree of `BasicJsonType` values.
Strings and numbers stay in the source text; only strings that contain escapes are decoded, into one buffer owned by
the document. [`basic_json_view`](../basic_json_view/index.md) is a read-only handle to one value of a
`basic_json_document`; [`materialize()`](../basic_json_view/materialize.md) turns a subtree back into the
`BasicJsonType` value that [`BasicJsonType::parse()`](../basic_json/parse.md) would have produced for it.
A document may **borrow** the text it was parsed from (the caller's buffer must then outlive the document) or **own**
it (a copy, or an rvalue `#!cpp std::string` that was moved in); see [`owns_source`](owns_source.md). `basic_json_document`
is move-only: copying a document would either duplicate a potentially large index and text, or leave two documents
claiming to borrow the same buffer, so it is disabled.
With `#!cpp Editable == true`, the document also offers [`set`](set.md), [`push_back`](push_back.md),
[`insert`](insert.md), and [`erase`](erase.md) to change values in place, see [Edits](#edits) below. The source text
itself is never written; a read-only document (`#!cpp Editable == false`, the default) does not carry any of the
bookkeeping edits need, and calling any of them on one fails to compile (`#!cpp static_assert`).
## Template parameters
`BasicJsonType`
: a specialization of [`basic_json`](../basic_json/index.md), for instance [`json`](../json.md) or
[`ordered_json`](../ordered_json.md). Only 64-bit `number_integer_t`/`number_unsigned_t` types are supported; this
is checked with a `static_assert`.
`Editable`
: whether the document supports [`set`](set.md), [`push_back`](push_back.md), [`insert`](insert.md), and
[`erase`](erase.md) (optional, `#!cpp false` by default). See [Edits](#edits) below.
## Specializations
- [**json_document**](../json_document.md) - read-only documents of the default specialization [`json`](../json.md)
- [**ordered_json_document**](../ordered_json_document.md) - read-only documents of
[`ordered_json`](../ordered_json.md)
- [**json_editable_document**](../json_editable_document.md) - editable documents of [`json`](../json.md)
- [**ordered_json_editable_document**](../ordered_json_editable_document.md) - editable documents of
[`ordered_json`](../ordered_json.md)
## Member types
- **view_type** - the type of view returned by [`root()`](root.md) (`#!cpp basic_json_view<BasicJsonType, Editable>`)
- **value_t** - the JSON type enumeration, see [`basic_json::value_t`](../basic_json/value_t.md)

- [**erase**](erase.md) - remove an object member, an array element, or the value a JSON pointer refers to
(`#!cpp Editable` documents only)
## Edits
An editable document (`#!cpp Editable == true`) can be changed after parsing, with [`set`](set.md),
[`push_back`](push_back.md), [`insert`](insert.md), and [`erase`](erase.md);
[`json_editable_document`](../json_editable_document.md) and
[`ordered_json_editable_document`](../ordered_json_editable_document.md) are the corresponding specializations. A few
points apply to every edit:
- **The source text is never written**, and the parsed index never moves: every value keeps the node it was parsed
into, so [views](../basic_json_view/index.md) taken before an edit stay valid, including
[`root()`](root.md). New values (and the element sequences of an edited array/object) go to storage owned by the
document, allocated on demand.
- **A view keeps referring to the same value.** After [`set`](set.md) replaces the value a view refers to, that view
sees the new value; a view of a value that a later edit replaces or drops keeps showing what it last held. An edit
of an array or object, however, **invalidates the iterators taken over it** (its members may now live in a
different sequence), and a string obtained with [`get_string()`](../basic_json_view/get_string.md) stays valid even
as further edits happen (earlier buffers of edited text are kept alive, not overwritten).
- **Values are accepted three ways:** a [`basic_json_view`](../basic_json_view/index.md) of *any* document
(read-only or editable; it is copied, nothing is shared with the source document), a `BasicJsonType` value, or
anything `BasicJsonType` can be constructed from (numbers, strings, `#!cpp bool`, `#!cpp nullptr`, containers, ...).
- [`dump()`](../basic_json_view/dump.md) writes an edited document with members in document order, new members at
the end, and, with [`number_format::source`](../basic_json_view/number_format.md), keeps the spelling of every
number that was not itself edited -- see [Editing a document](../../features/json_view.md#editing-a-document) for
why this matters.
- [`read()`](read.md) discards all edits, [`shrink_to_fit()`](shrink_to_fit.md) does not move the node index once
there are edits, and [`memory_usage()`](memory_usage.md) includes the memory edits use.
[`source_offset()`](../basic_json_view/source_offset.md) of a value introduced by an edit is
`#!cpp static_cast<std::size_t>(-1)`, the same value it reports for a decoded string.

# <small>nlohmann::basic_json_document::</small>insert
```cpp
template<typename I, typename V>
view_type insert(view_type array, I idx, V&& value);
```
Only an **editable** document (`#!cpp Editable == true`, e.g. [`json_editable_document`](../json_editable_document.md))
has `insert`; calling it on a read-only `basic_json_document` fails to compile (`#!cpp static_assert`).
Inserts `value` into `array` as a new element before position `idx`, which must not be past the end
(`#!cpp idx <= array.size()`; `#!cpp idx == array.size()` appends, like [`push_back`](push_back.md)). Unlike
[`push_back`](push_back.md), a [null](../basic_json_view/is_null.md) `array` does *not* first become an empty array:
`array` must already be an array.
`value` is accepted three ways: a [`basic_json_view`](../basic_json_view/index.md) of *any* document -- read-only or
editable, and it does not have to be `array`'s own document -- which is copied so that nothing is shared with the
source document afterward; a `BasicJsonType` value; or anything `BasicJsonType` can be constructed from (numbers,
strings, `#!cpp bool`, `#!cpp nullptr`, containers, ...).
## Template parameters
`I`
: an integral type other than `#!cpp bool`, deduced (overloads taking a `#!cpp bool` or a non-integral type for
`idx` do not participate in overload resolution).
`V`
: the type of `value`, deduced; see above for what is accepted.
## Parameters
`array` (in)
: the array to insert into
`idx` (in)
: the position to insert `value` before; a negative value throws (see [Exceptions](#exceptions))
`value` (in)
: the value to insert
## Return value
a view of the new element, now holding `value`
## Exception safety
Basic exception safety: `value` is fully encoded -- including the checks below -- into storage owned by the document
before anything already reachable from [`root()`](root.md) is touched, so a failure while encoding `value` (an
invalid argument, or `#!cpp std::bad_alloc`) leaves the document completely unchanged, other than memory allocated
for the encoding that is not reclaimed. A failure of a later allocation -- while `array` switches from its parsed
layout to a growable block, or while that block grows, see [Notes](#notes) -- can still leave `array` already
switched to that layout even though `value` itself was not inserted.
## Exceptions
Throws [`type_error.309`](../../home/exceptions.md#jsonexceptiontype_error309) if `array` is not an array -- the same
message [`BasicJsonType::insert`](../basic_json/insert.md) throws for the same type; a null `array` throws this too
(see above). Throws [`out_of_range.401`](../../home/exceptions.md#jsonexceptionout_of_range401) if `idx` is negative,
or if `#!cpp idx > array.size()`. Throws
[`invalid_iterator.202`](../../home/exceptions.md#jsonexceptioninvalid_iterator202) ("view does not belong to this
document") if `array` is a [discarded](../basic_json_view/is_discarded.md) view or a view of a *different* document.
Throws [`type_error.302`](../../home/exceptions.md#jsonexceptiontype_error302) if `value` is a
[discarded](../basic_json_view/is_discarded.md) view or a [discarded](../basic_json/is_discarded.md) `BasicJsonType`
value, and [`type_error.319`](../../home/exceptions.md#jsonexceptiontype_error319) if `value` is (or contains) a
binary value -- `BasicJsonType` can hold one, but a `json_document` cannot. Throws
[`type_error.316`](../../home/exceptions.md#jsonexceptiontype_error316) if `value` is (or contains) a string that is
not valid UTF-8, with the same message [`BasicJsonType::dump()`](../basic_json/dump.md) gives for that string.
## Complexity
Linear in the number of elements of `array` at or after `idx` (they move one slot over), plus time linear in the
size of `value` to encode it into the document's storage (constant for a scalar, linear in the number of nested
values for an array or object): like [`push_back`](push_back.md), the elements of `array` move to a growable block
of links the first time it is inserted into (or [`set`](set.md)/[`push_back`](push_back.md) on), and that block
grows in amortized constant time; inserting before the end within that block still shifts every later element.
## Notes
Like [`set`](set.md) on a member or an element, `insert` never moves an existing *element's value* -- only where
`array`'s *links* to its elements live -- so a view of an existing element of `array` stays valid across an
`insert`, and keeps referring to the same element even though its index shifts. Any iterator already taken over
`array` is invalidated, since it was walking the old layout. See [Edits](index.md#edits) for what stays valid across
an edit in general.
## Examples
??? example
The example below inserts a step into the middle of a deployment plan, without touching the steps that come
after it, and shows that a view taken before the insert keeps referring to the same element even though its
index shifts -- something a plain `json`/`ordered_json` array, or its `std::vector`-based storage, has no
equivalent for.

See the ownership table on [`parse`](parse.md#notes) for which inputs are borrowed and which are owned. A borrowed
document (`#!cpp owns_source() == false`) is only valid while the buffer it was parsed from is still alive.

# <small>nlohmann::basic_json_document::</small>parse
```cpp
// (1)
template<typename InputType>
static basic_json_document parse(InputType&& input,
const bool allow_exceptions = true,
const bool ignore_comments = false,
const bool ignore_trailing_commas = false);
// (2)
template<typename IteratorType>
static basic_json_document parse(IteratorType first, IteratorType last,
const bool allow_exceptions = true,
const bool ignore_comments = false,
const bool ignore_trailing_commas = false);
```
1. Deserialize from a compatible input, borrowing or owning it depending on its value category and type (see Notes).
2. Deserialize from a pair of input iterators.
Both overloads accept the same JSON text as [`BasicJsonType::parse()`](../basic_json/parse.md), with the same
`ignore_comments`/`ignore_trailing_commas` options, but build a [`basic_json_document`](index.md) (a flat index into
the input) instead of a tree of `BasicJsonType` values. The input must be byte-oriented (see the template parameters
below): not every input type of `BasicJsonType::parse()` is supported.
## Template parameters
`InputType`
: A byte-oriented input, one of:
- a `#!cpp std::string`, `#!cpp std::string_view`, or a C-style array of single-byte characters
- a pointer to a null-terminated string of single-byte characters (`#!cpp char`, `#!cpp signed char`,
`#!cpp unsigned char`, `#!cpp std::uint8_t`)
- a container for which `#!cpp obj.data()` and `#!cpp obj.size()` give contiguous single-byte access, e.g.
`#!cpp std::vector<char>` or `#!cpp std::vector<std::uint8_t>`
- an `#!cpp std::istream` object
- a wide string object (`#!cpp std::wstring`, `#!cpp std::u16string`, `#!cpp std::u32string`), which is converted
to UTF-8
Other inputs are not supported: a `#!cpp FILE*`, and pointers to or arrays of wide characters (`#!cpp wchar_t`,
`#!cpp char16_t`, `#!cpp char32_t`) are rejected at compile time by a `#!cpp static_assert`. (Use
[`BasicJsonType::parse()`](../basic_json/parse.md) for these.)
`IteratorType`
: an input iterator type, for instance a pair of pointers such as `ptr` and `ptr + len`, or a pair of
`#!cpp std::string::iterator`; the iterators of single-byte characters are borrowed or read like the byte inputs
above, those of wide characters are converted to UTF-8
## Parameters
`input` (in)
: Input to parse from.
`allow_exceptions` (in)
: whether to throw exceptions in case of a parse error (optional, `#!cpp true` by default)
`ignore_comments` (in)
: whether comments should be ignored and treated like whitespace (`#!cpp true`) or yield a parse error
(`#!cpp false`); (optional, `#!cpp false` by default)
`ignore_trailing_commas` (in)
: whether trailing commas in arrays or objects should be ignored and treated like whitespace (`#!cpp true`) or
yield a parse error (`#!cpp false`); (optional, `#!cpp false` by default)
`first` (in)
: iterator to the start of a character range
`last` (in)
: iterator to the end of a character range
## Return value
The parsed document. If `allow_exceptions` is `#!cpp false` and the input is not valid JSON, the returned document is
discarded; see [`is_discarded`](is_discarded.md).
## Exceptions
Throws the same exception [`BasicJsonType::parse()`](../basic_json/parse.md) throws for the same input and options --
the same exception id, message, and position -- because on a failing input the library's own parser is run on the
same bytes to produce the diagnostic. Additionally throws
[`out_of_range.416`](../../home/exceptions.md#jsonexceptionout_of_range416) if the input is 4294967280 bytes (4 GiB
minus 16 bytes) or larger, a size [`BasicJsonType::parse()`](../basic_json/parse.md) does not reject.
## Complexity
Linear in the length of the input.
## Notes
**Ownership.** Whether the document borrows `input` or owns a copy of it depends on its value category and type:
| `input` | ownership |
|--------------------------------------------------------------------------------------|--------------------------------------------------------------|
| lvalue byte container (`std::string`, `std::vector<char>`, ...), `std::string_view`, C string, character array | **borrowed** -- `input` must outlive the document |
| non-const rvalue `#!cpp std::string` | **owned**, moved in without a copy |
| other rvalue byte container (including a `#!cpp const` rvalue `#!cpp std::string`) | **owned**, copied |
| stream, wide string, or anything else read through the general input adapter | **owned**, read into a buffer (a stream is read to its end) |
For overload (2), a pair of pointers to single-byte integers (e.g. `#!cpp const char*`, `#!cpp std::uint8_t*`) is
borrowed. From C++20 on, so is any other contiguous iterator over single bytes, such as
`#!cpp std::vector<char>::iterator` or `#!cpp std::string::const_iterator`. Before C++20 these iterators cannot be
told apart from other class-type iterators, so their range is read into an owned buffer, as is any non-contiguous
range (e.g. of a `#!cpp std::list<char>`).
See [`owns_source`](owns_source.md) to check which happened after a call, and the
[feature page](../../features/json_view.md) for the reasoning.
**Numbers.** As for [`BasicJsonType::parse()`](../basic_json/parse.md), an integer literal too large for the 64-bit
integer type becomes a floating-point value.
**No lengths.** An integer argument that is not a `#!cpp bool` where the flags are expected -- for example
`#!cpp parse(ptr, len)` -- does not compile (the overload is deleted). Such a call would convert `len` to
`allow_exceptions` and read `ptr` as a null-terminated string, past the end of a buffer that has none. To parse a
buffer of a given length, pass a pair of pointers: `#!cpp parse(ptr, ptr + len)`. The same holds for
[`parse_copy`](parse_copy.md), [`accept`](accept.md), and [`read`](read.md).

# <small>nlohmann::basic_json_document::</small>parse_copy
```cpp
template<typename InputType>
static basic_json_document parse_copy(InputType&& input,
const bool allow_exceptions = true,
const bool ignore_comments = false,
const bool ignore_trailing_commas = false);
```
Deserialize from a compatible input, always taking the document's own copy of it, regardless of the value category or
type of `input`. Unlike [`parse()`](parse.md), the returned document never depends on `input` staying alive.
## Template parameters
`InputType`
: A compatible input; see [`parse`](parse.md#template-parameters).
## Parameters
`input` (in)
: Input to parse from.
`allow_exceptions` (in)
: whether to throw exceptions in case of a parse error (optional, `#!cpp true` by default)
`ignore_comments` (in)
: whether comments should be ignored and treated like whitespace (`#!cpp true`) or yield a parse error
(`#!cpp false`); (optional, `#!cpp false` by default)
`ignore_trailing_commas` (in)
: whether trailing commas in arrays or objects should be ignored and treated like whitespace (`#!cpp true`) or
yield a parse error (`#!cpp false`); (optional, `#!cpp false` by default)
## Return value
The parsed document, with [`owns_source()`](owns_source.md) `#!cpp true`. If `allow_exceptions` is `#!cpp false` and
the input is not valid JSON, the returned document is discarded; see [`is_discarded`](is_discarded.md).
## Exceptions
Same as [`parse`](parse.md#exceptions).
## Complexity
Linear in the length of the input.
## Notes
`parse_copy()` accepts and rejects exactly what [`parse()`](parse.md) does, and classifies numbers the same way; it
only differs in that the input is always copied rather than sometimes borrowed. Prefer [`parse()`](parse.md) when the
input's lifetime already covers the document's, since it avoids the copy for borrowed inputs.
An integer argument that is not a `#!cpp bool` where the flags are expected, such as `#!cpp parse_copy(ptr, len)`, does not
compile; see [`parse`](parse.md#notes).

# <small>nlohmann::basic_json_document::</small>push_back
```cpp
template<typename V>
view_type push_back(view_type array, V&& value);
```
Appends `value` as a new last element of `array`. A [null](../basic_json_view/is_null.md) `array` first becomes an
empty array, the same way [`set`](set.md) turns a null `object` into an empty object.
`value` is accepted three ways: a [`basic_json_view`](../basic_json_view/index.md) of *any* document -- read-only or
editable, and it does not have to be `array`'s own document -- which is copied so that nothing is shared with the
source document afterward; a `BasicJsonType` value; or anything `BasicJsonType` can be constructed from (numbers,
strings, `#!cpp bool`, `#!cpp nullptr`, containers, ...).
Only an **editable** document (`#!cpp Editable == true`, e.g. [`json_editable_document`](../json_editable_document.md))
has `push_back`; calling it on a read-only `basic_json_document` fails to compile (`#!cpp static_assert`).
## Template parameters
`V`
: the type of `value`, deduced; see above for what is accepted.
## Parameters
`array` (in)
: the array (or null value) to append to
`value` (in)
: the value to append
## Return value
a view of the new last element of `array`, now holding `value`
## Exception safety
Basic exception safety: `value` is fully encoded -- including the checks below -- into storage owned by the document
before anything already reachable from [`root()`](root.md) is touched, so a failure while encoding `value` (an
invalid argument, or `#!cpp std::bad_alloc`) leaves the document completely unchanged, other than memory allocated
for the encoding that is not reclaimed. A failure of a later allocation -- while `array` switches from its parsed
layout to a growable block, or while that block grows, see [Notes](#notes) -- can still leave a partial effect, such
as a null `array` argument already turned into an empty array even though `value` itself was not appended.
## Exceptions
Throws [`type_error.308`](../../home/exceptions.md#jsonexceptiontype_error308) if `array` is neither an array nor
null -- the same message [`BasicJsonType::push_back`](../basic_json/push_back.md) throws for the same type. Throws
[`invalid_iterator.202`](../../home/exceptions.md#jsonexceptioninvalid_iterator202) ("view does not belong to this
document") if `array` is a [discarded](../basic_json_view/is_discarded.md) view or a view of a *different* document.
Throws [`type_error.302`](../../home/exceptions.md#jsonexceptiontype_error302) if `value` is a
[discarded](../basic_json_view/is_discarded.md) view or a [discarded](../basic_json/is_discarded.md) `BasicJsonType`
value, and [`type_error.319`](../../home/exceptions.md#jsonexceptiontype_error319) if `value` is (or contains) a
binary value -- `BasicJsonType` can hold one, but a `json_document` cannot. Throws
[`type_error.316`](../../home/exceptions.md#jsonexceptiontype_error316) if `value` is (or contains) a string that is
not valid UTF-8, with the same message [`BasicJsonType::dump()`](../basic_json/dump.md) gives for that string.
## Complexity
Amortized constant, plus time linear in the size of `value` to encode it into the document's storage (constant for
a scalar, linear in the number of nested values for an array or object): the elements of `array` move to a growable
block of links the first time it is appended to (or [`set`](set.md) on), and that block itself grows -- doubling its
capacity, so the cost of growing it amortizes to constant per element -- only once it runs out of room. See
[Notes](#notes).
## Notes
Like [`set`](set.md) on a member or an element, `push_back` never moves an existing element itself -- only where
`array`'s *links* to its elements live -- so a view of an existing element of `array` stays valid across a
`push_back`, but any iterator already taken over `array` is invalidated, since it was walking the old layout. See
[Edits](index.md#edits) for what stays valid across an edit in general.
## Examples
??? example
The example below appends records to an array one at a time, as they might arrive from a stream of events,
without ever building a `BasicJsonType` value for the array or for the records already in it, and shows that a
view taken from an earlier `push_back` still refers to the same element once later ones have run.

--8<-- "examples/basic_json_document__push_back.cpp"

```cpp
template<typename InputType>
void read(InputType&& input,
const bool allow_exceptions = true,
const bool ignore_comments = false,
const bool ignore_trailing_commas = false);
```
(Re-)parses `input` into `#!cpp *this`, discarding the document's previous value and reusing its memory (the node
index, the decoded-string buffer, and, if applicable, the owned copy of the text) rather than allocating a fresh
document. [`parse()`](parse.md) is implemented in terms of this function, applied to a default-constructed document.
## Template parameters
`InputType`
: A compatible input; see [`parse`](parse.md#template-parameters).
## Parameters
`input` (in)
: Input to parse from.
`allow_exceptions` (in)
: whether to throw exceptions in case of a parse error (optional, `#!cpp true` by default)
`ignore_comments` (in)
: whether comments should be ignored and treated like whitespace (`#!cpp true`) or yield a parse error
(`#!cpp false`); (optional, `#!cpp false` by default)
`ignore_trailing_commas` (in)
: whether trailing commas in arrays or objects should be ignored and treated like whitespace (`#!cpp true`) or
yield a parse error (`#!cpp false`); (optional, `#!cpp false` by default)
## Exceptions
Same as [`parse`](parse.md#exceptions).
## Complexity
Linear in the length of the input.
## Notes
Every view taken from `#!cpp *this` before the call -- including the previous [`root()`](root.md) -- is invalidated,
whether or not the new parse succeeds; take fresh views from [`root()`](root.md) afterward.
`input` is borrowed or owned by the same rules as [`parse()`](parse.md#notes); a document can borrow on one call and
own on the next, since ownership is decided freshly each time.
Reusing a document matters most for large inputs: the operating system provides the memory of a fresh node index one
page at a time, and every page costs a page fault the first time it is written. On x86-64 Linux (4 KiB pages), parsing
a 55 MB document into a reused document took about 40 % less time than parsing it into a fresh one. Programs that parse
many documents of similar size should therefore keep one document and call `read()`.
An integer argument that is not a `#!cpp bool` where the flags are expected, such as `#!cpp read(ptr, len)`, does not
compile; see [`parse`](parse.md#notes).
## Examples

1. Returns a view of the root value of the document.
2. Deleted: the view of a temporary document would dangle.
## Return value
A [`view_type`](index.md#member-types) (i.e. `#!cpp basic_json_view<BasicJsonType>`) for the root value, or a
discarded view if the document is [discarded](is_discarded.md).
## Exception safety
No-throw guarantee: this function never throws exceptions.
## Complexity
Constant.
## Notes
**Lifetime.** A view refers into the document, so the document must outlive it. `root()` can therefore only be called
on a document that has a name (an lvalue); calling it on a temporary does not compile:
```cpp
auto v = json_document::parse(text).root(); // error: the document is destroyed at the end of the statement
auto doc = json_document::parse(text); // OK: keep the document alive
auto v = doc.root();
```
`root()` is a cheap handle into the document's index, not a copy of anything; call it as often as needed. The
returned view is valid under the same conditions as any other view of the document -- see
[Object inspection](../basic_json_view/index.md) -- in particular, it is invalidated by the next
[`read()`](read.md) or [`shrink_to_fit()`](shrink_to_fit.md) on this document.

Only an **editable** document (`#!cpp Editable == true`, e.g. [`json_editable_document`](../json_editable_document.md))
has `set`; calling it on a read-only `basic_json_document` fails to compile (`#!cpp static_assert`).
1. Replaces the value `target` refers to with `value`.
2. Sets the member `key` of the object `object` to `value`: assigns it if `object` already has a member with this
key -- the first one, should the key occur more than once, and the later duplicates are then dropped (see the
[Notes](#notes) below) -- or appends a new member at the end otherwise. A [null](../basic_json_view/is_null.md)
`object` first becomes an empty object.
3. Assigns `value` to the element at index `idx` of the array `array`, which must already exist (`#!cpp idx <
array.size()`).
4. Sets the value the JSON pointer `ptr` refers to, relative to [`root()`](root.md), to `value`. The *parent* of the
target must already exist: an object member is set as in 2. (added if it does not exist yet), an array element is
assigned as in 3., and a last reference token of `#!cpp "-"`, or equal to the size of the array, appends `value`
instead, exactly as [`push_back`](push_back.md) would. A [null](../basic_json_view/is_null.md) parent becomes what
[`basic_json::operator[]`](../basic_json/operator%5B%5D.md) with a JSON pointer makes of it: an array if the last
reference token is `#!cpp "-"` or consists of digits only (for an index beyond 0, the array is first filled with
null values up to that index), an object otherwise. An empty `ptr` sets [`root()`](root.md) itself, as in 1.
In every overload, `value` is accepted three ways: a [`basic_json_view`](../basic_json_view/index.md) of *any*
document -- read-only or editable, and it does not have to be `target`'s/`object`'s/`array`'s own document -- which
is copied so that nothing is shared with the source document afterward; a `BasicJsonType` value; or anything
`BasicJsonType` can be constructed from (numbers, strings, `#!cpp bool`, `#!cpp nullptr`, containers, ...).
## Template parameters
`V`
: the type of `value`, deduced; see above for what is accepted.
`I`
: an integral type other than `#!cpp bool`, deduced (overloads taking a `#!cpp bool` or a non-integral type for
`idx` do not participate in overload resolution).
## Parameters
`target` (in)
: the value to replace
`object` (in)
: the object (or null value) whose member to set
`array` (in)
: the array whose element to assign
`key` (in)
: the key of the member to set
`idx` (in)
: the index of the element to assign; a negative value throws (see [Exceptions](#exceptions))
`ptr` (in)
: a JSON pointer to the value to set, relative to `root()`
`value` (in)
: the new value
## Return value
1. a view of `target`, now holding `value`
2. a view of the member `key` of `object`, now holding `value`
3. a view of the element `idx` of `array`, now holding `value`
4. a view of the value `ptr` refers to, now holding `value`
## Exception safety
Basic exception safety: `value` is fully encoded -- including the checks below -- into storage owned by the document
before anything already reachable from [`root()`](root.md) is touched, so a failure while encoding `value` (an
invalid argument, or `#!cpp std::bad_alloc`) leaves the document completely unchanged, other than memory allocated
for the encoding that is not reclaimed. A failure of a later allocation -- while an edited array or object switches
from its parsed layout to a growable block, see [Notes](#notes) -- can still leave a partial effect, such as a
[null](../basic_json_view/is_null.md) `object`/`array` argument already turned into an empty object/array even
though `value` itself was not linked in. Likewise, a failure of `value` in 4. leaves a null parent that is set with an
index beyond 0 already filled with the null values before the index.
## Exceptions
1. Throws [`type_error.302`](../../home/exceptions.md#jsonexceptiontype_error302) if `value` is a
[discarded](../basic_json_view/is_discarded.md) view, or a [discarded](../basic_json/is_discarded.md)
`BasicJsonType` value (e.g. `#!cpp BasicJsonType(value_t::discarded)`) -- an object or array `value`, of either
kind, is fine and is encoded as a whole subtree.
2. Throws [`type_error.305`](../../home/exceptions.md#jsonexceptiontype_error305) if `object` is neither an object
nor null -- the same message [`operator[]`](../basic_json_view/operator%5B%5D.md) throws for a string argument on
such a value. Throws [`type_error.316`](../../home/exceptions.md#jsonexceptiontype_error316) if `key` is not
valid UTF-8, with the same message [`BasicJsonType::dump()`](../basic_json/dump.md) gives for that string.
Also throws what 1. throws for `value`.
3. Throws `type_error.305` if `array` is not an array -- the same message `operator[]` throws for a numeric argument
on such a value. Throws [`out_of_range.401`](../../home/exceptions.md#jsonexceptionout_of_range401) if `idx` is
negative, or if `#!cpp idx >= array.size()`. Also throws what 1. throws for `value`.
4. Throws what [`at`](../basic_json_view/at.md) throws (overload 3) for resolving `ptr`'s parent, except that a
missing object member or an array index equal to the array's size at the very last reference token is not an
error there (it becomes a new member or an appended element) instead of
[`out_of_range.403`](../../home/exceptions.md#jsonexceptionout_of_range403)/[`out_of_range.402`](../../home/exceptions.md#jsonexceptionout_of_range402).
For the last reference token itself: if the parent is an object (or a primitive value, where it throws
`type_error.305`), throws what 2. throws; if the parent is an array, throws what 3. throws for an index that is
out of range, or, for a token that is not a valid array index,
[`parse_error.106`](../../home/exceptions.md#jsonexceptionparse_error106) (a leading `#!cpp '0'`),
[`parse_error.109`](../../home/exceptions.md#jsonexceptionparse_error109) (not a number),
[`out_of_range.410`](../../home/exceptions.md#jsonexceptionout_of_range410) (too large for `size_type`), or
[`out_of_range.404`](../../home/exceptions.md#jsonexceptionout_of_range404) (an empty token); the same errors are
thrown for a null parent and a token of digits (the parent is not changed then), and
[`out_of_range.401`](../../home/exceptions.md#jsonexceptionout_of_range401) if the index is 4294967295 or more.
Also throws what 1. throws for `value`.
Every overload also throws [`type_error.319`](../../home/exceptions.md#jsonexceptiontype_error319) if `value` is (or
contains) a binary value -- `BasicJsonType` can hold one, but a `json_document` cannot -- and
[`invalid_iterator.202`](../../home/exceptions.md#jsonexceptioninvalid_iterator202) ("view does not belong to this
document") if `target`/`object`/`array` is a [discarded](../basic_json_view/is_discarded.md) view or a view of a
*different* document (overloads 1-3 only; overload 4 always starts from this document's own [`root()`](root.md)).
## Complexity
1. Linear in the size of `value` (encoding it into the document's storage): constant for a scalar, linear in the
number of nested values for an array or object. If `target` is itself an array or object that spans more than one
node in its parent's original, unedited layout, and `value` is a scalar, replacing it additionally costs time
linear in the size of the document, the *first* time (the parent of `target` is looked up from
[`root()`](root.md), and then switches to links) -- see [Notes](#notes). Once the parent has links, `target` is
replaced in constant time: setting every element of a large array one after the other is linear overall. To avoid
the lookup altogether, use 3. (or 2. for an object), which know the parent.
2. Linear in the number of members of `object`, to find an existing member with `key`, plus the complexity of 1. for
`value`.
3. Constant, plus the complexity of 1. for `value`.
4. Linear in the number of reference tokens of `ptr` and, for each token, in the number of members of the object at
that level or the index into the array (as [`at`](../basic_json_view/at.md)), plus the complexity of 2. or 3. for
the last token; for a null parent and an index, linear in the index.
## Notes
!!! info "Duplicate keys"
If `object` already has more than one member with `key` (2.), the *first* one is assigned `value` and every
later member with the same key is removed -- so that a lookup, an iteration, and
[`materialize()`](../basic_json_view/materialize.md) of `object` afterward all agree on a single value for
`key`, the same way [`operator[]`](../basic_json_view/operator%5B%5D.md) already picks the first occurrence of a
duplicate key for reading. See the [Notes on duplicate keys](../basic_json_view/operator%5B%5D.md#notes) of
`operator[]`.
Setting a member (2.) or an element (3., through 4.) of an array or object whose elements have not been edited
before switches it from its parsed layout to a growable block holding links to its elements; a later
[`push_back`](push_back.md) or `set` on the same container reuses that block, growing it (amortized constant time)
only once it runs out of room. This never moves an element itself -- only where the container's *links* to its
elements live -- so a view of an element stays valid, but any iterator already taken over the container is
invalidated, since it was walking the old layout. See [Edits](index.md#edits) for what stays valid across an edit in
general.
The same switch happens, for the same reason, when overload 1. replaces a multi-node array/object value with a
scalar: the *parent's* element sequence is what has to switch to links, not `target` itself, because the parent
originally stepped over `target`'s whole subtree by its node count, which no longer applies once `target` is a
one-node scalar.
## Examples
??? example "Example: (1)/(2)/(3)/(4) replace a value, set a member, assign an element, set via a JSON pointer"
The example below edits a small configuration document -- replacing a value, adding an object member, assigning
an array element, and reaching a field through a JSON pointer -- and shows what
[`dump()`](../basic_json_view/dump.md) preserves that is lost once the same edits are made on a `BasicJsonType`
value instead: the order object members were written in, and the exact spelling of a number that was never
touched.

# <small>nlohmann::basic_json_document::</small>shrink_to_fit
```cpp
void shrink_to_fit();
```
Releases capacity that is no longer needed, both of the node index and of the buffer for decoded strings (strings that
contained escape sequences), e.g. after [`read()`](read.md) replaced a large document with a much smaller one. Like
`#!cpp std::vector::shrink_to_fit()`, this is a non-binding request: the library may keep more capacity than strictly
necessary.
## Exception safety
Strong guarantee: if an exception is thrown, there are no changes to the document.
## Exceptions
May throw `#!cpp std::bad_alloc` if the reallocation fails; on exception, the document is unchanged.
## Complexity
Linear in [`node_count()`](node_count.md) plus the length of the decoded strings.
## Notes
!!! warning "Invalidates views"
Unlike moving the document, `shrink_to_fit()` **invalidates every view taken from this document before the
call**, including a previously obtained [`root()`](root.md): the node index is moved into a new, smaller
allocation, and the old one is freed. Take a fresh view from [`root()`](root.md) after calling this function.
This is unlike `#!cpp std::vector::shrink_to_fit()`, which promises nothing about validity but in practice often
leaves iterators alone when it did not need to reallocate; here, an implementation that avoids a reallocation when
possible would be an internal optimization only, not a guarantee to rely on.

Returns the parsed text, whether it is borrowed from the caller or owned by the document.

A `#!cpp string_view_t` (`#!cpp std::string_view` on C++17 and newer) over the parsed text, or an empty one if the
document is [discarded](is_discarded.md).
## Exception safety

```
1. Returns the value of the object member with key `key` -- the first one, should the key occur more than once (see
[Notes on duplicate keys](operator[].md#notes)).
2. Returns the array element at index `idx`. The template accepts every integer type except `#!cpp bool` and
`#!cpp std::size_t` and forwards to the `size_type` overload, as for [`operator[]`](operator[].md); a negative
`idx` is out of range.
3. Returns the value a JSON pointer `ptr` refers to, starting at this value.
## Parameters
`key` (in)
: object key of the element to access
`idx` (in)
: index of the element to access
`ptr` (in)
: JSON pointer to the element to access
## Return value
1. the value of the first member with key `key`
2. the element at index `idx`
3. the value `ptr` resolves to, starting at this value
## Exception safety
Strong exception safety: if an exception is thrown, there are no changes to the view or the document it refers to.
## Exceptions
1. The function can throw the following exceptions, both with the same message as the corresponding call to
[`BasicJsonType::at`](../basic_json/at.md):
- Throws [`type_error.304`](../../home/exceptions.md#jsonexceptiontype_error304) if the value is not an object.
- Throws [`out_of_range.403`](../../home/exceptions.md#jsonexceptionout_of_range403) if no member has key `key`.
2. The function can throw the following exceptions, both with the same message as the corresponding call to
[`BasicJsonType::at`](../basic_json/at.md):
- Throws [`type_error.304`](../../home/exceptions.md#jsonexceptiontype_error304) if the value is not an array.
- Throws [`out_of_range.401`](../../home/exceptions.md#jsonexceptionout_of_range401) if `#!cpp idx >= size()`.
3. The function can throw the following exceptions, all with the same message as the corresponding call to
[`BasicJsonType::at`](../basic_json/at.md):
- Throws [`parse_error.106`](../../home/exceptions.md#jsonexceptionparse_error106) if an array index in `ptr`
begins with `#!cpp '0'`.
- Throws [`parse_error.109`](../../home/exceptions.md#jsonexceptionparse_error109) if an array index in `ptr` is
not a number.
- Throws [`out_of_range.401`](../../home/exceptions.md#jsonexceptionout_of_range401) if an array index in `ptr`
is out of range.
- Throws [`out_of_range.402`](../../home/exceptions.md#jsonexceptionout_of_range402) if a reference token is
`#!cpp "-"` at an array -- `at` never inserts an element, so `#!cpp "-"` is always invalid.
- Throws [`out_of_range.403`](../../home/exceptions.md#jsonexceptionout_of_range403) if a reference token names
an object member that does not exist.
- Throws [`out_of_range.404`](../../home/exceptions.md#jsonexceptionout_of_range404) if `ptr` cannot be resolved
because a reference token is used on a primitive value.
None of these exceptions carry a [`JSON_DIAGNOSTICS`](../macros/json_diagnostics.md) path: the view has no
`BasicJsonType` value to point at, so the exception is created without one, even if `BasicJsonType` was built with
`JSON_DIAGNOSTICS` enabled.
## Complexity
1. Linear in the number of members: as for [`ordered_json`](../ordered_json.md), members are compared one after
another, in document order, stopping at the first match. Each comparison first checks the
key's length -- already known from the index, without reading the key bytes -- before comparing its content.
Objects with 128 or more members get a hash index while parsing, so that a lookup in them takes constant time
on average.
2. Linear in `idx`: elements are skipped one at a time from the first one, since they are not a fixed size in the
index (unlike `BasicJsonType`'s array, which is random-access).
3. Linear in the number of reference tokens of `ptr` and, for each token, in the number of members of the object at
that level (as 1.) or the index into the array (as 2.).
## Notes
!!! warning "Duplicate keys: the first member wins"
If the source text repeats a key, this resolves to the *first* member with it, not to the last one that
[`materialize()`](materialize.md) and `parse()` keep. See the [Notes on duplicate keys](operator[].md#notes) of
`operator[]` and [Duplicate keys](../../features/json_view.md#duplicate-keys) for the reasons and for how to get
the last value.
Unlike [`operator[]`](operator[].md), which returns a [discarded](is_discarded.md) view for a missing key or an
out-of-range index, `at` always throws -- exactly as `BasicJsonType::at` does, and with the same messages, so
existing error handling written against `BasicJsonType::at` keeps working unchanged when switched to a view. This
also holds for overload 3: unlike [`operator[]`](operator[].md) with a JSON pointer, which returns a discarded view
for a missing key or an out-of-range index, `at` throws for those too (`out_of_range.403`/`out_of_range.401`).
## Examples
??? example "Example: (1)/(2) access specified element with bounds checking"
The example below reads required fields out of a service configuration with `at`, and shows that the exceptions
it throws -- for a wrong type and for a missing key -- carry the same messages
[`BasicJsonType::at`](../basic_json/at.md) would produce for the same JSON text.
```cpp
--8<-- "examples/basic_json_view__at.cpp"
```
Output:
```json

??? example "Example: (3) access specified element via JSON pointer with bounds checking"

that [`BasicJsonType::at`](../basic_json/at.md) throws for the same pointer and the same document.

# <small>nlohmann::basic_json_view::</small>back
```cpp
basic_json_view back() const;
```
Returns the last element of an array, the last member value of an object, or the value itself if it is primitive
(as for [`BasicJsonType::back()`](../basic_json/back.md), a primitive value is a range of one element).
## Return value
The last element or member value. For a primitive value (number, string, boolean), the value itself.
## Exception safety
Strong exception safety: if an exception is thrown, there are no changes to the view or the document it refers to.
## Exceptions
Throws [`invalid_iterator.214`](../../home/exceptions.md#jsonexceptioninvalid_iterator214) if the view is
[null](is_null.md) or [discarded](is_discarded.md), or if it is an empty array or object.
This exception does not carry a [`JSON_DIAGNOSTICS`](../macros/json_diagnostics.md) path: the view has no
`BasicJsonType` value to point at, so the exception is created without one, even if `BasicJsonType` was built with
`JSON_DIAGNOSTICS` enabled.
## Complexity
Linear in the size of the array or object: unlike [`front()`](front.md), which only ever looks at the first
element, `back()` has to walk every element to find where they end, since elements are not a fixed size in the
index.
## Notes
Unlike [`BasicJsonType::back()`](../basic_json/back.md), which has undefined behavior for an empty array or object,
`back()` throws `invalid_iterator.214` in that case -- the same way it already does for `#!json null` and for a
discarded view, where `BasicJsonType::back()` also throws.
## Examples
??? example
The example below reads only the final status of a build log with `back()`. Even though `back()` is linear in
the number of events (unlike [`front()`](front.md), which is constant), it still avoids building a

Creates an invalid (discarded) view: [`type()`](type.md) is `#!cpp value_t::discarded` and
[`is_discarded()`](is_discarded.md) is `#!cpp true`.
This is the only constructor a caller can use directly. Every other view is obtained from a
[`basic_json_document`](../basic_json_document/index.md), via [`root()`](../basic_json_document/root.md) or by
navigating into a container with [`operator[]`](operator[].md), [`at`](at.md), [`front`](front.md), [`back`](back.md),
[`find`](find.md), or iteration.
## Exception safety
No-throw guarantee: this constructor never throws exceptions.
## Complexity

## Notes
`basic_json_view` is trivially copyable (it holds two pointers), so a default-constructed view can be used as a

# <small>nlohmann::basic_json_view::</small>begin
```cpp
iterator begin() const noexcept;
```
Returns an iterator to the first element of an array, or the first member value of an object, in **document order**
-- the order the values appear in the source text, not sorted by key. A primitive value iterates as a range of one
element (itself); `#!json null` and a [discarded](is_discarded.md) view iterate as an empty range.
## Return value
Iterator to the first element.
## Exception safety
No-throw guarantee: this function never throws exceptions.
## Complexity
Constant.
## Notes
For an object, iteration visits **every** member, including all occurrences of a duplicate key -- unlike
[`operator[]`](operator[].md), [`at`](at.md), [`find`](find.md), [`contains`](contains.md), and [`count`](count.md),
which all resolve to the *first* member with a given key. See the
[Notes on duplicate keys](operator[].md#notes) of `operator[]`.
Because objects are iterated in document order rather than sorted by key, the order seen here can differ from what
iterating the [`materialize()`](materialize.md)d `BasicJsonType` value would produce: a `#!cpp basic_json` object
(`std::map`-backed by default) sorts its keys, while a view does not.
## Examples
??? example
The example below iterates a log record's members with `begin()`/[`end()`](end.md) and prints them in the order
they were written. Materializing the record into a `BasicJsonType` object and iterating that would instead print
