2833 | @brief the JSON type enumeration | ||
2834 | |||
2835 | This enumeration collects the different JSON types. It is internally used to | ||
2836 | distinguish 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 | ||
2845 | number_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 | ||
2849 | approximate integers which do not fit in the limits of their respective type. | ||
2850 | |||

2852 | value with the default value for a given type | ||

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 | ---------|----------|----------|----------|---------|---------|----------|----------- | ||

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. | ||

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

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

12818 | This 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) | ||
