| 106 | @brief the JSON type enumeration |
| 107 | |
| 108 | This enumeration collects the different JSON types. It is internally used to |
| 109 | distinguish the stored values, and the functions @ref basic_json::is_null(), |
| 110 | @ref basic_json::is_object(), @ref basic_json::is_array(), |
| 111 | @ref basic_json::is_string(), @ref basic_json::is_boolean(), |
| 112 | @ref basic_json::is_number() (with @ref basic_json::is_number_integer(), |
| 113 | @ref basic_json::is_number_unsigned(), and @ref basic_json::is_number_float()), |
| 114 | @ref basic_json::is_discarded(), @ref basic_json::is_primitive(), and |
| 115 | @ref basic_json::is_structured() rely on it. |
| 116 | |
| 117 | @note There are three enumeration entries (number_integer, number_unsigned, and |
| 118 | number_float), because the library distinguishes these three types for numbers: |
| 119 | @ref basic_json::number_unsigned_t is used for unsigned integers, |
| 120 | @ref basic_json::number_integer_t is used for signed integers, and |
| 121 | @ref basic_json::number_float_t is used for floating-point numbers or to |
| 122 | approximate integers which do not fit in the limits of their respective type. |
| 123 | |
| 124 | @sa see @ref basic_json::basic_json(const value_t value_type) -- create a JSON |
| 125 | value with the default value for a given type |
| 126 | |

| 7333 | |
| 7334 | This function scans a string according to Sect. 6 of RFC 8259. |
| 7335 | |
| 7336 | The function is realized with a deterministic finite state machine derived |
| 7337 | from the grammar described in RFC 8259. Starting in state "init", the |
| 7338 | input is read and used to determined the next state. Only state "done" |
| 7339 | accepts the number. State "error" is a trap state to model errors. In the |
| 7340 | table below, "anything" means any character but the ones listed before. |
| 7341 | |
| 7342 | state | 0 | 1-9 | e E | + | - | . | anything |
| 7343 | ---------|----------|----------|----------|---------|---------|----------|----------- |
| 7344 | init | zero | any1 | [error] | [error] | minus | [error] | [error] |
| 7345 | minus | zero | any1 | [error] | [error] | [error] | [error] | [error] |
| 7346 | zero | done | done | exponent | done | done | decimal1 | done |
| 7347 | any1 | any1 | any1 | exponent | done | done | decimal1 | done |
| 7348 | decimal1 | decimal2 | decimal2 | [error] | [error] | [error] | [error] | [error] |
| 7349 | decimal2 | decimal2 | decimal2 | exponent | done | done | done | done |
| 7350 | exponent | any2 | any2 | [error] | sign | sign | [error] | [error] |
| 7351 | sign | any2 | any2 | [error] | [error] | [error] | [error] | [error] |
| 7352 | any2 | any2 | any2 | done | done | done | done | done |
| 7353 | |
| 7354 | The state machine is realized with one label per state (prefixed with |
| 7355 | "scan_number_") and `goto` statements between them. The state machine |
| 7356 | contains cycles, but any cycle can be left when EOF is read. Therefore, |
| 7357 | the function is guaranteed to terminate. |
| 7358 | |
| 7359 | During scanning, the read bytes are stored in token_buffer. This string is |
| 7360 | then converted to a signed integer, an unsigned integer, or a |
| 7361 | floating-point number. |
| 7362 | |
| 7363 | @return token_type::value_unsigned, token_type::value_integer, or |
| 7364 | token_type::value_float if number could be successfully scanned, |
| 7365 | token_type::parse_error otherwise |
| 7366 | |
| 7367 | @note The scanner is independent of the current locale. Internally, the |
| 7368 | locale's decimal point is used instead of `.` to work with the |
| 7369 | locale-dependent converters. |

| 11391 | This class implements a both iterators (iterator and const_iterator) for the |
| 11392 | @ref basic_json class. |
| 11393 | @note An iterator is called *initialized* when a pointer to a JSON value has |
| 11394 | been set (e.g., by a constructor or a copy assignment). If the iterator is |
| 11395 | default-constructed, it is *uninitialized* and most methods are undefined. |
| 11396 | **The library uses assertions to detect calls on uninitialized iterators.** |

| 11399 | [BidirectionalIterator](https://en.cppreference.com/w/cpp/named_req/BidirectionalIterator): |
| 11400 | The iterator that can be moved can be moved in both directions (i.e. |
| 11401 | incremented and decremented). |
| 11402 | @since version 1.0.0, simplified in version 2.0.9, change to bidirectional |
