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 | |

149 | - discarded values are not comparable | |
150 | - binary is represented as a b"" string in python and directly comparable to a | |
151 | string; however, making a binary array directly comparable with a string would | |
152 | be surprising behavior in a JSON file. | |

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. | |

11390 | @brief a template for a bidirectional iterator for the @ref basic_json class | |
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.** | |
11397 | @requirement The class satisfies the following concept requirements: | |
11398 | - | |
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 | |
11403 | iterators in version 3.0.0 (see https://github.com/nlohmann/json/issues/593) | |
