| 2976 | @brief the JSON type enumeration |
| 2977 | |
| 2978 | This enumeration collects the different JSON types. It is internally used to |
| 2979 | distinguish the stored values, and the functions @ref basic_json::is_null(), |
| 2980 | @ref basic_json::is_object(), @ref basic_json::is_array(), |
| 2981 | @ref basic_json::is_string(), @ref basic_json::is_boolean(), |
| 2982 | @ref basic_json::is_number() (with @ref basic_json::is_number_integer(), |
| 2983 | @ref basic_json::is_number_unsigned(), and @ref basic_json::is_number_float()), |
| 2984 | @ref basic_json::is_discarded(), @ref basic_json::is_primitive(), and |
| 2985 | @ref basic_json::is_structured() rely on it. |
| 2986 | |
| 2987 | @note There are three enumeration entries (number_integer, number_unsigned, and |
| 2988 | number_float), because the library distinguishes these three types for numbers: |
| 2989 | @ref basic_json::number_unsigned_t is used for unsigned integers, |
| 2990 | @ref basic_json::number_integer_t is used for signed integers, and |
| 2991 | @ref basic_json::number_float_t is used for floating-point numbers or to |
| 2992 | approximate integers which do not fit in the limits of their respective type. |
| 2993 | |
| 2994 | @sa see @ref basic_json::basic_json(const value_t value_type) -- create a JSON |
| 2995 | value with the default value for a given type |

| 7954 | |
| 7955 | This function scans a string according to Sect. 6 of RFC 8259. |
| 7956 | |
| 7957 | The function is realized with a deterministic finite state machine derived |
| 7958 | from the grammar described in RFC 8259. Starting in state "init", the |
| 7959 | input is read and used to determined the next state. Only state "done" |
| 7960 | accepts the number. State "error" is a trap state to model errors. In the |
| 7961 | table below, "anything" means any character but the ones listed before. |
| 7962 | |
| 7963 | state | 0 | 1-9 | e E | + | - | . | anything |
| 7964 | ---------|----------|----------|----------|---------|---------|----------|----------- |
| 7965 | init | zero | any1 | [error] | [error] | minus | [error] | [error] |
| 7966 | minus | zero | any1 | [error] | [error] | [error] | [error] | [error] |
| 7967 | zero | done | done | exponent | done | done | decimal1 | done |
| 7968 | any1 | any1 | any1 | exponent | done | done | decimal1 | done |
| 7969 | decimal1 | decimal2 | decimal2 | [error] | [error] | [error] | [error] | [error] |
| 7970 | decimal2 | decimal2 | decimal2 | exponent | done | done | done | done |
| 7971 | exponent | any2 | any2 | [error] | sign | sign | [error] | [error] |
| 7972 | sign | any2 | any2 | [error] | [error] | [error] | [error] | [error] |
| 7973 | any2 | any2 | any2 | done | done | done | done | done |
| 7974 | |
| 7975 | The state machine is realized with one label per state (prefixed with |
| 7976 | "scan_number_") and `goto` statements between them. The state machine |
| 7977 | contains cycles, but any cycle can be left when EOF is read. Therefore, |
| 7978 | the function is guaranteed to terminate. |
| 7979 | |
| 7980 | During scanning, the read bytes are stored in token_buffer. This string is |
| 7981 | then converted to a signed integer, an unsigned integer, or a |
| 7982 | floating-point number. |
| 7983 | |
| 7984 | @return token_type::value_unsigned, token_type::value_integer, or |
| 7985 | token_type::value_float if number could be successfully scanned, |
| 7986 | token_type::parse_error otherwise |
| 7987 | |
| 7988 | @note The scanner is independent of the current locale. Internally, the |
| 7989 | locale's decimal point is used instead of `.` to work with the |
| 7990 | locale-dependent converters. |

| 13589 | @brief a template for a bidirectional iterator for the @ref basic_json class |
| 13590 | This class implements a both iterators (iterator and const_iterator) for the |
| 13591 | @ref basic_json class. |
| 13592 | @note An iterator is called *initialized* when a pointer to a JSON value has |
| 13593 | been set (e.g., by a constructor or a copy assignment). If the iterator is |
| 13594 | default-constructed, it is *uninitialized* and most methods are undefined. |
| 13595 | **The library uses assertions to detect calls on uninitialized iterators.** |
| 13596 | @requirement The class satisfies the following concept requirements: |
| 13597 | - |
| 13598 | [BidirectionalIterator](https://en.cppreference.com/w/cpp/named_req/BidirectionalIterator): |
| 13599 | The iterator that can be moved can be moved in both directions (i.e. |
| 13600 | incremented and decremented). |
| 13601 | @since version 1.0.0, simplified in version 2.0.9, change to bidirectional |
| 13602 | iterators in version 3.0.0 (see https://github.com/nlohmann/json/issues/593) |

| 14349 | @brief a template for a reverse iterator class |
| 14350 | |
| 14351 | @tparam Base the base iterator type to reverse. Valid types are @ref |
| 14352 | iterator (to create @ref reverse_iterator) and @ref const_iterator (to |
| 14353 | create @ref const_reverse_iterator). |
| 14354 | |
| 14355 | @requirement The class satisfies the following concept requirements: |
| 14356 | - |
| 14357 | [BidirectionalIterator](https://en.cppreference.com/w/cpp/named_req/BidirectionalIterator): |
| 14358 | The iterator that can be moved can be moved in both directions (i.e. |
| 14359 | incremented and decremented). |
| 14360 | - [OutputIterator](https://en.cppreference.com/w/cpp/named_req/OutputIterator): |
| 14361 | It is possible to write to the pointed-to element (only if @a Base is |
| 14362 | @ref iterator). |
