2833@brief the JSON type enumeration


2834


2835This enumeration collects the different JSON types. It is internally used to


2836distinguish the stored values, and the functions @ref basic_json::is_null(),


2837@ref basic_json::is_object(), @ref basic_json::is_array(),


2838@ref basic_json::is_string(), @ref basic_json::is_boolean(),


2839@ref basic_json::is_number() (with @ref basic_json::is_number_integer(),


2840@ref basic_json::is_number_unsigned(), and @ref basic_json::is_number_float()),


2841@ref basic_json::is_discarded(), @ref basic_json::is_primitive(), and


2842@ref basic_json::is_structured() rely on it.


2843


2844@note There are three enumeration entries (number_integer, number_unsigned, and


2845number_float), because the library distinguishes these three types for numbers:


2846@ref basic_json::number_unsigned_t is used for unsigned integers,


2847@ref basic_json::number_integer_t is used for signed integers, and


2848@ref basic_json::number_float_t is used for floating-point numbers or to


2849approximate integers which do not fit in the limits of their respective type.

3088// Class template representing a compile-time integer sequence. An instantiation


3089// of `integer_sequence<T, Ints...>` has a sequence of integers encoded in its


3090// type through its template arguments (which is a common need when


3091// working with C++11 variadic templates). `absl::integer_sequence` is designed


3092// to be a drop-in replacement for C++14's `std::integer_sequence`.


3093//


3094// Example:


3095//


3096//   template< class T, T... Ints >


3097//   void user_function(integer_sequence<T, Ints...>);


3098//


3099//   int main()

3101//     // user_function's `T` will be deduced to `int` and `Ints...`


3102//     // will be deduced to `0, 1, 2, 3, 4`.


3103//     user_function(make_integer_sequence<int, 5>());


3104//   }

8231    @brief scan a number literal


8232


8233    This function scans a string according to Sect. 6 of RFC 8259.


8234


8235    The function is realized with a deterministic finite state machine derived


8236    from the grammar described in RFC 8259. Starting in state "init", the


8237    input is read and used to determined the next state. Only state "done"


8238    accepts the number. State "error" is a trap state to model errors. In the


8239    table below, "anything" means any character but the ones listed before.


8240


8241    state    | 0        | 1-9      | e E      | +       | -       | .        | anything


8242    ---------|----------|----------|----------|---------|---------|----------|-----------


8243    init     | zero     | any1     | [error]  | [error] | minus   | [error]  | [error]


8244    minus    | zero     | any1     | [error]  | [error] | [error] | [error]  | [error]


8245    zero     | done     | done     | exponent | done    | done    | decimal1 | done


8246    any1     | any1     | any1     | exponent | done    | done    | decimal1 | done


8247    decimal1 | decimal2 | decimal2 | [error]  | [error] | [error] | [error]  | [error]


8248    decimal2 | decimal2 | decimal2 | exponent | done    | done    | done     | done


8249    exponent | any2     | any2     | [error]  | sign    | sign    | [error]  | [error]


8250    sign     | any2     | any2     | [error]  | [error] | [error] | [error]  | [error]


8251    any2     | any2     | any2     | done     | done    | done    | done     | done


8252


8253    The state machine is realized with one label per state (prefixed with


8254    "scan_number_") and `goto` statements between them. The state machine


8255    contains cycles, but any cycle can be left when EOF is read. Therefore,


8256    the function is guaranteed to terminate.


8257


8258    During scanning, the read bytes are stored in token_buffer. This string is


8259    then converted to a signed integer, an unsigned integer, or a


8260    floating-point number.


8261


8262    @return token_type::value_unsigned, token_type::value_integer, or


8263            token_type::value_float if number could be successfully scanned,


8264            token_type::parse_error otherwise


8265


8266    @note The scanner is independent of the current locale. Internally, the


8267          locale's decimal point is used instead of `.` to work with the


8268          locale-dependent converters.

12642@brief an iterator for primitive JSON types


12643


12644This class models an iterator for primitive JSON types (boolean, number,


12645string). It's only purpose is to allow the iterator/const_iterator classes


12646to "iterate" over primitive values. Internally, the iterator is modeled by


12647a `difference_type` variable. Value begin_value (`0`) models the begin,


12648end_value (`1`) models past the end.

12817@brief a template for a bidirectional iterator for the @ref basic_json class


12818This class implements a both iterators (iterator and const_iterator) for the


12819@ref basic_json class.


12820@note An iterator is called *initialized* when a pointer to a JSON value has


12821      been set (e.g., by a constructor or a copy assignment). If the iterator is


12822      default-constructed, it is *uninitialized* and most methods are undefined.


12823      **The library uses assertions to detect calls on uninitialized iterators.**


12824@requirement The class satisfies the following concept requirements:


12825-


12826[BidirectionalIterator](https://en.cppreference.com/w/cpp/named_req/BidirectionalIterator):


12827  The iterator that can be moved can be moved in both directions (i.e.


12828  incremented and decremented).


12829@since version 1.0.0, simplified in version 2.0.9, change to bidirectional


12830       iterators in version 3.0.0 (see https://github.com/nlohmann/json/issues/593)

13568@brief a template for a reverse iterator class


13569


13570@tparam Base the base iterator type to reverse. Valid types are @ref


13571iterator (to create @ref reverse_iterator) and @ref const_iterator (to


13572create @ref const_reverse_iterator).


13573


13574@requirement The class satisfies the following concept requirements:


13575-


13576[BidirectionalIterator](https://en.cppreference.com/w/cpp/named_req/BidirectionalIterator):


13577  The iterator that can be moved can be moved in both directions (i.e.


13578  incremented and decremented).


13579- [OutputIterator](https://en.cppreference.com/w/cpp/named_req/OutputIterator):


13580  It is possible to write to the pointed-to element (only if @a Base is


13581  @ref iterator).

17058// The choice of (alpha,gamma) determines the size of the table and the form of


17059// the digit generation procedure. Using (alpha,gamma)=(-60,-32) works out well


17060// in practice:


17061//


17062// The idea is to cut the number c * w = f * 2^e into two parts, which can be


17063// processed independently: An integral part p1, and a fractional part p2:


17064//


17065//      f * 2^e = ( (f div 2^-e) * 2^-e + (f mod 2^-e) ) * 2^e

17067//              = p1 + p2 * 2^e


17068//


17069// The conversion of p1 into decimal form requires a series of divisions and


17070// modulos by (a power of) 10. These operations are faster for 32-bit than for


17071// 64-bit integers, so p1 should ideally fit into a 32-bit integer. This can be


17072// achieved by choosing


17073//


17074//      -e >= 32   or   e <= -32 := gamma


17075//


17076// In order to convert the fractional part


17077//


17078//      p2 * 2^e = p2 / 2^-e = d[-1] / 10^1 + d[-2] / 10^2 + ...


17079//


17080// into decimal form, the fraction is repeatedly multiplied by 10 and the digits


17081// d[-i] are extracted in order:


17082//


17083//      (10 * p2) div 2^-e = d[-1]


17084//      (10 * p2) mod 2^-e = d[-2] / 10^1 + ...


17085//


17086// The multiplication by 10 must not overflow. It is sufficient to choose


17087//


17088//      10 * p2 < 16 * p2 = 2^4 * p2 <= 2^64.


17089//


17090// Since p2 = f mod 2^-e < 2^-e,

17970    @brief internal implementation of the serialization function


17971


17972    This function is called by the public member function dump and organizes


17973    the serialization internally. The indentation level is propagated as


17974    additional parameter. In case of arrays and objects, the function is


17975    called recursively.


17976


17977    - strings and object keys are escaped using `escape_string()`


17978    - integer numbers are converted implicitly via `operator<<`


17979    - floating-point numbers are converted to a string using `"%g"` format


17980    - binary values are serialized as objects containing the subtype and the


17981      byte array


17982


17983    @param[in] val               value to serialize


17984    @param[in] pretty_print      whether the output shall be pretty-printed


17985    @param[in] ensure_ascii If @a ensure_ascii is true, all non-ASCII characters


17986    in the output are escaped with `\uXXXX` sequences, and the result consists


17987    of ASCII characters only.


17988    @param[in] indent_step       the indent level


17989    @param[in] current_indent    the current indent level (only used internally)

18764    @brief check whether a string is UTF-8 encoded


18765


18766    The function checks each byte of a string whether it is UTF-8 encoded. The


18767    result of the check is stored in the @a state parameter. The function must


18768    be called initially with state 0 (accept). State 1 means the string must


18769    be rejected, because the current byte is not allowed. If the string is


18770    completely processed, but the state is non-zero, the string ended


18771    prematurely; that is, the last byte indicated more bytes should have


18772    followed.


18773


18774    @param[in,out] state  the state of the decoding


18775    @param[in,out] codep  codepoint (valid only if resulting state is UTF8_ACCEPT)


18776    @param[in] byte       next byte to decode


18777    @return               new state


18778


18779    @note The function has been edited: a std::array is used.

19833    @brief checks the class invariants


19834


19835    This function asserts the class invariants. It needs to be called at the


19836    end of every constructor to make sure that created objects respect the


19837    invariant. Furthermore, it has to be called each time the type of a JSON


19838    value is changed, because the invariant expresses a relationship between


19839    @a m_type and @a m_value.


19840


19841    Furthermore, the parent relation is checked for arrays and objects: If


19842    @a check_parents true and the value is an array or object, then the


19843    container's elements must have the current value as parent.


19844


19845    @param[in] check_parents  whether the parent relation should be checked.


19846               The value is true by default and should only be set to false


19847               during destruction of objects when the invariant does not


19848               need to hold.
