| 2836 | @brief the JSON type enumeration |
| 2837 | |
| 2838 | This enumeration collects the different JSON types. It is internally used to |
| 2839 | distinguish the stored values, and the functions @ref basic_json::is_null(), |
| 2840 | @ref basic_json::is_object(), @ref basic_json::is_array(), |
| 2841 | @ref basic_json::is_string(), @ref basic_json::is_boolean(), |
| 2842 | @ref basic_json::is_number() (with @ref basic_json::is_number_integer(), |
| 2843 | @ref basic_json::is_number_unsigned(), and @ref basic_json::is_number_float()), |
| 2844 | @ref basic_json::is_discarded(), @ref basic_json::is_primitive(), and |
| 2845 | @ref basic_json::is_structured() rely on it. |
| 2846 | |
| 2847 | @note There are three enumeration entries (number_integer, number_unsigned, and |
| 2848 | number_float), because the library distinguishes these three types for numbers: |
| 2849 | @ref basic_json::number_unsigned_t is used for unsigned integers, |
| 2850 | @ref basic_json::number_integer_t is used for signed integers, and |
| 2851 | @ref basic_json::number_float_t is used for floating-point numbers or to |
| 2852 | approximate integers which do not fit in the limits of their respective type. |
| 2853 | |
| 2854 | @sa see @ref basic_json::basic_json(const value_t value_type) -- create a JSON |
| 2855 | value with the default value for a given type |

| 8237 | This function scans a string according to Sect. 6 of RFC 8259. |
| 8238 | |
| 8239 | The function is realized with a deterministic finite state machine derived |
| 8240 | from the grammar described in RFC 8259. Starting in state "init", the |
| 8241 | input is read and used to determined the next state. Only state "done" |
| 8242 | accepts the number. State "error" is a trap state to model errors. In the |
| 8243 | table below, "anything" means any character but the ones listed before. |
| 8244 | |
| 8245 | state | 0 | 1-9 | e E | + | - | . | anything |
| 8246 | ---------|----------|----------|----------|---------|---------|----------|----------- |
| 8247 | init | zero | any1 | [error] | [error] | minus | [error] | [error] |
| 8248 | minus | zero | any1 | [error] | [error] | [error] | [error] | [error] |

| 8255 | any2 | any2 | any2 | done | done | done | done | done |
| 8256 | |
| 8257 | The state machine is realized with one label per state (prefixed with |
| 8258 | "scan_number_") and `goto` statements between them. The state machine |
| 8259 | contains cycles, but any cycle can be left when EOF is read. Therefore, |
| 8260 | the function is guaranteed to terminate. |

| 12821 | @brief a template for a bidirectional iterator for the @ref basic_json class |
| 12822 | This class implements a both iterators (iterator and const_iterator) for the |
| 12823 | @ref basic_json class. |
| 12824 | @note An iterator is called *initialized* when a pointer to a JSON value has |
| 12825 | been set (e.g., by a constructor or a copy assignment). If the iterator is |
| 12826 | default-constructed, it is *uninitialized* and most methods are undefined. |
| 12827 | **The library uses assertions to detect calls on uninitialized iterators.** |
| 12828 | @requirement The class satisfies the following concept requirements: |
| 12829 | - |
| 12830 | [BidirectionalIterator](https://en.cppreference.com/w/cpp/named_req/BidirectionalIterator): |
| 12831 | The iterator that can be moved can be moved in both directions (i.e. |
| 12832 | incremented and decremented). |
| 12833 | @since version 1.0.0, simplified in version 2.0.9, change to bidirectional |
| 12834 | iterators in version 3.0.0 (see https://github.com/nlohmann/json/issues/593) |

| 13579 | - |
| 13580 | [BidirectionalIterator](https://en.cppreference.com/w/cpp/named_req/BidirectionalIterator): |
| 13581 | The iterator that can be moved can be moved in both directions (i.e. |
| 13582 | incremented and decremented). |
| 13583 | - [OutputIterator](https://en.cppreference.com/w/cpp/named_req/OutputIterator): |
| 13584 | It is possible to write to the pointed-to element (only if @a Base is |
| 13585 | @ref iterator). |
