1815 json.exception.parse_error.101 | parse error at 2: unexpected end of input; expected string literal | This error indicates a syntax error while deserializing a JSON text. The error message describes that an unexpected token (character) was encountered, and the member @a byte indicates the error position.
|
|
ferencd@0
|
1816 json.exception.parse_error.102 | parse error at 14: missing or wrong low surrogate | JSON uses the `\uxxxx` format to describe Unicode characters. Code points above above 0xFFFF are split into two `\uxxxx` entries ("surrogate pairs"). This error indicates that the surrogate pair is incomplete or contains an invalid code point.
|
|
ferencd@0
|
1817 json.exception.parse_error.103 | parse error: code points above 0x10FFFF are invalid | Unicode supports code points up to 0x10FFFF. Code points above 0x10FFFF are invalid.
|
|
ferencd@0
|
1818 json.exception.parse_error.104 | parse error: JSON patch must be an array of objects | [RFC 6902](https://tools.ietf.org/html/rfc6902) requires a JSON Patch document to be a JSON document that represents an array of objects.
|
|
ferencd@0
|
1819 json.exception.parse_error.105 | parse error: operation must have string member 'op' | An operation of a JSON Patch document must contain exactly one "op" member, whose value indicates the operation to perform. Its value must be one of "add", "remove", "replace", "move", "copy", or "test"; other values are errors.
|
|
ferencd@0
|
1820 json.exception.parse_error.106 | parse error: array index '01' must not begin with '0' | An array index in a JSON Pointer ([RFC 6901](https://tools.ietf.org/html/rfc6901)) may be `0` or any number without a leading `0`.
|
|
ferencd@0
|
1821 json.exception.parse_error.107 | parse error: JSON pointer must be empty or begin with '/' - was: 'foo' | A JSON Pointer must be a Unicode string containing a sequence of zero or more reference tokens, each prefixed by a `/` character.
|
|
ferencd@0
|
1822 json.exception.parse_error.108 | parse error: escape character '~' must be followed with '0' or '1' | In a JSON Pointer, only `~0` and `~1` are valid escape sequences.
|
|
ferencd@0
|
1823 json.exception.parse_error.109 | parse error: array index 'one' is not a number | A JSON Pointer array index must be a number.
|
|
ferencd@0
|
1824 json.exception.parse_error.110 | parse error at 1: cannot read 2 bytes from vector | When parsing CBOR or MessagePack, the byte vector ends before the complete value has been read.
|
|
ferencd@0
|
1825 json.exception.parse_error.112 | parse error at 1: error reading CBOR; last byte: 0xF8 | Not all types of CBOR or MessagePack are supported. This exception occurs if an unsupported byte was read.
|
|
ferencd@0
|
1826 json.exception.parse_error.113 | parse error at 2: expected a CBOR string; last byte: 0x98 | While parsing a map key, a value that is not a string has been read.
|
|
ferencd@0
|
1827 json.exception.parse_error.114 | parse error: Unsupported BSON record type 0x0F | The parsing of the corresponding BSON record type is not implemented (yet).
|
|
ferencd@0
|
1828
|
|
ferencd@0
|
1829 @note For an input with n bytes, 1 is the index of the first character and n+1
|
|
ferencd@0
|
1830 is the index of the terminating null byte or the end of file. This also

2335
|
|
ferencd@0
|
2336 A JSON pointer defines a string syntax for identifying a specific value
|
|
ferencd@0
|
2337 within a JSON document. It can be used with functions `at` and
|
|
ferencd@0
|
2338 `operator[]`. Furthermore, JSON pointers are the base for JSON patches.

2728 @brief the JSON type enumeration
|
|
ferencd@0
|
2729
|
|
ferencd@0
|
2730 This enumeration collects the different JSON types. It is internally used to
|
|
ferencd@0
|
2731 distinguish the stored values, and the functions @ref basic_json::is_null(),
|
|
ferencd@0
|
2732 @ref basic_json::is_object(), @ref basic_json::is_array(),
|
|
ferencd@0
|
2733 @ref basic_json::is_string(), @ref basic_json::is_boolean(),
|
|
ferencd@0
|
2734 @ref basic_json::is_number() (with @ref basic_json::is_number_integer(),
|
|
ferencd@0
|
2735 @ref basic_json::is_number_unsigned(), and @ref basic_json::is_number_float()),
|
|
ferencd@0
|
2736 @ref basic_json::is_discarded(), @ref basic_json::is_primitive(), and
|
|
ferencd@0
|
2737 @ref basic_json::is_structured() rely on it.
|
|
ferencd@0
|
2738
|
|
ferencd@0
|
2739 @note There are three enumeration entries (number_integer, number_unsigned, and
|
|
ferencd@0
|
2740 number_float), because the library distinguishes these three types for numbers:
|
|
ferencd@0
|
2741 @ref basic_json::number_unsigned_t is used for unsigned integers,
|
|
ferencd@0
|
2742 @ref basic_json::number_integer_t is used for signed integers, and
|
|
ferencd@0
|
2743 @ref basic_json::number_float_t is used for floating-point numbers or to
|
|
ferencd@0
|
2744 approximate integers which do not fit in the limits of their respective type.
|
|
ferencd@0
|
2745
|
|
ferencd@0

7860 This function scans a string according to Sect. 6 of RFC 7159.
|
|
ferencd@0
|
7861
|
|
ferencd@0
|
7862 The function is realized with a deterministic finite state machine derived
|
|
ferencd@0
|
7863 from the grammar described in RFC 7159. Starting in state "init", the
|
|
ferencd@0
|
7864 input is read and used to determined the next state. Only state "done"
|
|
ferencd@0
|
7865 accepts the number. State "error" is a trap state to model errors. In the
|
|
ferencd@0
|
7866 table below, "anything" means any character but the ones listed before.

7880 The state machine is realized with one label per state (prefixed with

7881 "scan_number_") and `goto` statements between them. The state machine
|
|
ferencd@0
|
7882 contains cycles, but any cycle can be left when EOF is read. Therefore,

9055 This class models an iterator for primitive JSON types (boolean, number,

9056 string). It's only purpose is to allow the iterator/const_iterator classes
|

ferencd@0

9057 to "iterate" over primitive values. Internally, the iterator is modeled by
|
|
ferencd@0
|
9058 a `difference_type` variable. Value begin_value (`0`) models the begin,
|
|
ferencd@0
|
9059 end_value (`1`) models past the end.

9218 @brief a template for a bidirectional iterator for the @ref basic_json class
|

ferencd@0

9219 This class implements a both iterators (iterator and const_iterator) for the
|
|
ferencd@0
|
9220 @ref basic_json class.
|
|
ferencd@0
|
9221 @note An iterator is called *initialized* when a pointer to a JSON value has
|
|
ferencd@0
|
9222 been set (e.g., by a constructor or a copy assignment). If the iterator is
|
|
ferencd@0
|
9223 default-constructed, it is *uninitialized* and most methods are undefined.
|
|
ferencd@0
|
9224 **The library uses assertions to detect calls on uninitialized iterators.**
|
|
ferencd@0
|
9225 @requirement The class satisfies the following concept requirements:
|
|
ferencd@0
|
9226 -
|
|
ferencd@0
|
9227 [BidirectionalIterator](https://en.cppreference.com/w/cpp/named_req/BidirectionalIterator):
|
|
ferencd@0
|
9228 The iterator that can be moved can be moved in both directions (i.e.
|
|
ferencd@0
|
9229 incremented and decremented).
|
|
ferencd@0
|
9230 @since version 1.0.0, simplified in version 2.0.9, change to bidirectional
|

13715 called recursively.

13716
|
|
ferencd@0
|
13717 - strings and object keys are escaped using `escape_string()`
|

ferencd@0
|
13718 - integer numbers are converted implicitly via `operator<<`
|
|
ferencd@0
|
13719 - floating-point numbers are converted to a string using `"%g"` format

ferencd@0
|
14398 The function checks each byte of a string whether it is UTF-8 encoded. The
|
|
ferencd@0
|
14399 result of the check is stored in the @a state parameter. The function must
|
|
ferencd@0
|
14400 be called initially with state 0 (accept). State 1 means the string must
|
|
ferencd@0
|
14401 be rejected, because the current byte is not allowed. If the string is
|
|
ferencd@0
|
14402 completely processed, but the state is non-zero, the string ended
|
|
ferencd@0
|
14403 prematurely; that is, the last byte indicated more bytes should have
|
|
ferencd@0
|
14404 followed.

|
14805 [RFC 7159](http://rfc7159.net/rfc7159) describes JSON objects as follows:
|
|
ferencd@0
|
14806 > An object is an unordered collection of zero or more name/value pairs,
|
|
ferencd@0
|
14807 > where a name is a string and a value is a string, number, boolean, null,
|

ferencd@0
|
14808 > object, or array.
|
|
ferencd@0
|
14809
|
|
ferencd@0
|
14810 To store objects in C++, a type is defined by the template parameters

14814 `std::unordered_map`)
|
|
ferencd@0
|
14815 @tparam StringType the type of the keys or names (e.g., `std::string`).
|
|
ferencd@0
|
14816 The comparison function `std::less<StringType>` is used to order elements
|

ferencd@0

14817 inside the container.

14836 #### Behavior
|
|
ferencd@0
|
14837
|
|
ferencd@0
|
14838 The choice of @a object_t influences the behavior of the JSON class. With
|
|
ferencd@0
|
14839 the default type, objects have the following behavior:
|
|
ferencd@0
|
14840
|
|
ferencd@0
|
14841 - When all names are unique, objects will be interoperable in the sense
|
|
ferencd@0
|
14842 that all software implementations receiving that object will agree on
|
|
ferencd@0
|
14843 the name-value mappings.
|
|
ferencd@0
|
14844 - When the names within an object are not unique, it is unspecified which
|
|
ferencd@0
|
14845 one of the values for a given key will be chosen. For instance,
|
|
ferencd@0
|
14846 `{"key": 2, "key": 1}` could be equal to either `{"key": 1}` or
|
|
ferencd@0
|
14847 `{"key": 2}`.
|
|
ferencd@0
|
14848 - Internally, name/value pairs are stored in lexicographical order of the
|
|
ferencd@0
|
14849 names. Objects will also be serialized (see @ref dump) in this order.
|
|
ferencd@0
|
14850 For instance, `{"b": 1, "a": 2}` and `{"a": 2, "b": 1}` will be stored
|
|
ferencd@0
|
14851 and serialized as `{"a": 2, "b": 1}`.
|
|
ferencd@0
|
14852 - When comparing objects, the order of the name/value pairs is irrelevant.
|
|
ferencd@0
|
14853 This makes objects interoperable in the sense that they will not be
|
|
ferencd@0
|
14854 affected by these differences. For instance, `{"b": 1, "a": 2}` and
|
|
ferencd@0
|
14855 `{"a": 2, "b": 1}` will be treated as equal.
|
|
ferencd@0
|

|
|
ferencd@0
|
14861
|
|
ferencd@0
|
14862 In this class, the object's limit of nesting is not explicitly constrained.
|
|
ferencd@0
|
14863 However, a maximum depth of nesting may be introduced by the compiler or
|
|
ferencd@0
|
14864 runtime environment. A theoretical limit can be queried by calling the
|
|
ferencd@0
|
14865 @ref max_size function of a JSON object.

14867 #### Storage
|
|
ferencd@0
|
14868
|
|
ferencd@0
|
14869 Objects are stored as pointers in a @ref basic_json type. That is, for any
|
|
ferencd@0
|
14870 access to object values, a pointer of type `object_t*` must be
|
|
ferencd@0
|
14871 dereferenced.

|
ferencd@0
|
14879 name/value pairs in a different order than they were originally stored. In

|
ferencd@0
|
14880 fact, keys will be traversed in alphabetical order as `std::map` with
|
|
ferencd@0
|
14881 `std::less` is used by default. Please note this behavior conforms to [RFC
|
|
ferencd@0
|
14882 7159](http://rfc7159.net/rfc7159), because any order implements the

|
|
ferencd@0
|
15027
|
|
ferencd@0
|
15028 This description includes both integer and floating-point numbers.
|
|
ferencd@0
|
15029 However, C++ allows more precise storage if it is known whether the number
|
|
ferencd@0
|
15030 is a signed integer, an unsigned integer or a floating-point number.
|
|
ferencd@0
|
15031 Therefore, three different types, @ref number_integer_t, @ref
|
|
ferencd@0
|
15032 number_unsigned_t and @ref number_float_t are used.

|
ferencd@0

|
15034 To store integer numbers in C++, a type is defined by the template
|
|

|
15035 parameter @a NumberIntegerType which chooses the type to use.
|
|
ferencd@0
|
15036
|
|
ferencd@0

15037 #### Default type
|
|
ferencd@0
|
15038

|
ferencd@0
|
15039 With the default values for @a NumberIntegerType (`int64_t`), the default

15046 #### Default behavior
|
|
ferencd@0
|
15047
|
|
ferencd@0
|
15048 - The restrictions about leading zeros is not enforced in C++. Instead,
|
|
ferencd@0
|
15049 leading zeros in integer literals lead to an interpretation as octal
|
|
ferencd@0
|
15050 number. Internally, the value will be stored as decimal number. For
|
|
ferencd@0
|
15051 instance, the C++ integer literal `010` will be serialized to `8`.
|
|
ferencd@0
|
15052 During deserialization, leading zeros yield an error.
|
|
ferencd@0
|
15053 - Not-a-number (NaN) values will be serialized to `null`.
|
|
ferencd@0
|
15054

|
15055 #### Limits

15056
|
|
ferencd@0

|
15058 > An implementation may set limits on the range and precision of numbers.
|
|
ferencd@0
|
15059
|
|
ferencd@0
|
15060 When the default type is used, the maximal integer number that can be
|
|
ferencd@0
|
15061 stored is `9223372036854775807` (INT64_MAX) and the minimal integer number
|
|
ferencd@0
|
15062 that can be stored is `-9223372036854775808` (INT64_MIN). Integer numbers
|
|
ferencd@0
|
15063 that are out of range will yield over/underflow when used in a
|
|
ferencd@0
|
15064 constructor. During deserialization, too large or small integer numbers
|
|
ferencd@0
|
15065 will be automatically be stored as @ref number_unsigned_t or @ref
|
|
ferencd@0
|
15066 number_float_t.

|

ferencd@0
|
15090
|
|
ferencd@0
|
15091 [RFC 7159](http://rfc7159.net/rfc7159) describes numbers as follows:
|
|
ferencd@0
|
15092 > The representation of numbers is similar to that used in most
|
|
ferencd@0
|
15093 > programming languages. A number is represented in base 10 using decimal
|
|
ferencd@0
|
15094 > digits. It contains an integer component that may be prefixed with an
|
|
ferencd@0
|
15095 > optional minus sign, which may be followed by a fraction part and/or an
|
|
ferencd@0
|
15096 > exponent part. Leading zeros are not allowed. (...) Numeric values that
|
|
ferencd@0
|
15097 > cannot be represented in the grammar below (such as Infinity and NaN)
|
|
ferencd@0
|
15098 > are not permitted.
|
|
ferencd@0
|
15099
|
|
ferencd@0
|
15100 This description includes both integer and floating-point numbers.
|
|
ferencd@0
|
15101 However, C++ allows more precise storage if it is known whether the number
|
|
ferencd@0
|
15102 is a signed integer, an unsigned integer or a floating-point number.
|
|
ferencd@0
|
15103 Therefore, three different types, @ref number_integer_t, @ref
|
|
ferencd@0
|
15104 number_unsigned_t and @ref number_float_t are used.
|
|
ferencd@0
|
15105
|
|
ferencd@0
|
15106 To store unsigned integer numbers in C++, a type is defined by the
|
|
ferencd@0
|
15107 template parameter @a NumberUnsignedType which chooses the type to use.
|
|
ferencd@0
|
15108
|
|
ferencd@0
|
15109 #### Default type
|
|
ferencd@0
|
15110
|
|
ferencd@0
|
15111 With the default values for @a NumberUnsignedType (`uint64_t`), the
|
|
ferencd@0
|
15112 default value for @a number_unsigned_t is:
|
|
ferencd@0
|
15113
|
|
ferencd@0
|
15114 @code {.cpp}
|
|
ferencd@0
|
15115 uint64_t
|
|
ferencd@0
|
15116 @endcode
|
|
ferencd@0
|
15117
|
|
ferencd@0
|
15118 #### Default behavior
|
|
ferencd@0
|
15119
|
|
ferencd@0
|
15120 - The restrictions about leading zeros is not enforced in C++. Instead,
|
|
ferencd@0
|
15121 leading zeros in integer literals lead to an interpretation as octal
|
|
ferencd@0
|
15122 number. Internally, the value will be stored as decimal number. For
|
|
ferencd@0
|
15123 instance, the C++ integer literal `010` will be serialized to `8`.
|
|
ferencd@0
|
15124 During deserialization, leading zeros yield an error.
|
|
ferencd@0
|
15125 - Not-a-number (NaN) values will be serialized to `null`.
|
|
ferencd@0
|
15126
|
|
ferencd@0
|
15127 #### Limits
|
|
ferencd@0
|
15128
|
|
ferencd@0
|
15129 [RFC 7159](http://rfc7159.net/rfc7159) specifies:
|
|
ferencd@0
|
15130 > An implementation may set limits on the range and precision of numbers.
|
|
ferencd@0
|
15131
|
|
ferencd@0
|
15132 When the default type is used, the maximal integer number that can be
|
|
ferencd@0
|
15133 stored is `18446744073709551615` (UINT64_MAX) and the minimal integer
|
|
ferencd@0
|
15134 number that can be stored is `0`. Integer numbers that are out of range
|
|
ferencd@0
|
15135 will yield over/underflow when used in a constructor. During
|
|
ferencd@0
|
15136 deserialization, too large or small integer numbers will be automatically
|
|
ferencd@0
|
15137 be stored as @ref number_integer_t or @ref number_float_t.
|
|
ferencd@0
|
15138
|
|
ferencd@0
|
15139 [RFC 7159](http://rfc7159.net/rfc7159) further states:
|
|
ferencd@0
|
15140 > Note that when such software is used, numbers that are integers and are
|
|
ferencd@0
|
15141 > in the range \f$[-2^{53}+1, 2^{53}-1]\f$ are interoperable in the sense
|
|
ferencd@0
|
15142 > that implementations will agree exactly on their numeric values.
|
|
ferencd@0
|
15143
|
|
ferencd@0
|
15144 As this range is a subrange (when considered in conjunction with the
|
|
ferencd@0
|
15145 number_integer_t type) of the exactly supported range [0, UINT64_MAX],
|
|
ferencd@0
|
15146 this class's integer type is interoperable.
|
|
ferencd@0
|
15147

|
ferencd@0
|
15148 #### Storage
|
|
ferencd@0
|
15149
|

ferencd@0

15150 Integer number values are stored directly inside a @ref basic_json type.

|
|
ferencd@0
|
15171 This description includes both integer and floating-point numbers.
|
|
ferencd@0
|
15172 However, C++ allows more precise storage if it is known whether the number
|
|
ferencd@0
|
15173 is a signed integer, an unsigned integer or a floating-point number.
|
|
ferencd@0
|
15174 Therefore, three different types, @ref number_integer_t, @ref
|
|
ferencd@0
|
15175 number_unsigned_t and @ref number_float_t are used.
|
|
ferencd@0
|
15176
|
|
ferencd@0
|
15177 To store floating-point numbers in C++, a type is defined by the template
|
|
ferencd@0
|
15178 parameter @a NumberFloatType which chooses the type to use.
|
|
ferencd@0
|
15179
|
|
ferencd@0
|
15180 #### Default type
|
|
ferencd@0
|
15181
|
|
ferencd@0
|
15182 With the default values for @a NumberFloatType (`double`), the default
|
|
ferencd@0
|
15183 value for @a number_float_t is:
|
|
ferencd@0
|
15184
|
|
ferencd@0
|
15185 @code {.cpp}

|
ferencd@0
|
15189 #### Default behavior
|
|
ferencd@0
|
15190
|
|
ferencd@0
|
15191 - The restrictions about leading zeros is not enforced in C++. Instead,
|
|
ferencd@0
|
15192 leading zeros in floating-point literals will be ignored. Internally,
|
|
ferencd@0
|
15193 the value will be stored as decimal number. For instance, the C++
|
|
ferencd@0
|
15194 floating-point literal `01.2` will be serialized to `1.2`. During
|
|
ferencd@0
|
15195 deserialization, leading zeros yield an error.
|
|
ferencd@0
|
15196 - Not-a-number (NaN) values will be serialized to `null`.
|
|
ferencd@0
|
15197
|
|
ferencd@0
|
15198 #### Limits

|
15199
|
|
ferencd@0
|
15200 [RFC 7159](http://rfc7159.net/rfc7159) states:

15201 > This specification allows implementations to set limits on the range and

15203 > 754-2008 binary64 (double precision) numbers is generally available and

|
ferencd@0

15204 > widely used, good interoperability can be achieved by implementations

ferencd@0

|
|
ferencd@0
|
15208
|
|
ferencd@0

15209 This implementation does exactly follow this approach, as it uses double

ferencd@0
|
15482 With a parser callback function, the result of parsing a JSON text can be
|
|
ferencd@0
|
15483 influenced. When passed to @ref parse, it is called on certain events
|
|
ferencd@0
|
15484 (passed as @ref parse_event_t via parameter @a event) with a set recursion
|
|
ferencd@0
|
15485 depth @a depth and context JSON value @a parsed. The return value of the
|
|
ferencd@0
|
15486 callback function is a boolean indicating whether the element that emitted
|
|
ferencd@0
|
15487 the callback shall be kept or not.
|
|
ferencd@0
|
15488
|
|
ferencd@0
|
15489 We distinguish six scenarios (determined by the event type) in which the
|
|
ferencd@0
|
15490 callback function can be called. The following table describes the values
|
|
ferencd@0
|
15491 of the parameters @a depth, @a event, and @a parsed.

15504 Discarding a value (i.e., returning `false`) has different effects
|
|
ferencd@0
|
15505 depending on the context in which function was called:
|
|
ferencd@0
|
15506
|
|
ferencd@0
|
15507 - Discarded values in structured types are skipped. That is, the parser
|
|
ferencd@0
|
15508 will behave as if the discarded value was never read.
|
|
ferencd@0
|
15509 - In case a value outside a structured type is skipped, it is replaced
|
|
ferencd@0
|
15510 with `null`. This case happens if the top-level element is skipped.

15742 @brief create a container (array or object) from an initializer list

ferencd@0
|
15744 Creates a JSON value of type array or object from the passed initializer
|
|
ferencd@0
|
15745 list @a init. In case @a type_deduction is `true` (default), the type of
|
|
ferencd@0
|
15746 the JSON value to be created is deducted from the initializer list @a init
|
|
ferencd@0
|
15747 according to the following rules:
|
|
ferencd@0
|
15748
|
|
ferencd@0
|
15749 1. If the list is empty, an empty JSON object value `{}` is created.
|
|
ferencd@0
|
15750 2. If the list consists of pairs whose first element is a string, a JSON
|
|
ferencd@0
|
15751 object value is created where the first elements of the pairs are
|
|
ferencd@0
|
15752 treated as keys and the second elements are as values.
|
|
ferencd@0
|
15753 3. In all other cases, an array is created.
|
|
ferencd@0
|
15754
|
|
ferencd@0
|
15755 The rules aim to create the best fit between a C++ initializer list and
|
|
ferencd@0
|
15756 JSON values. The rationale is as follows:
|
|
ferencd@0
|
15757
|
|
ferencd@0
|
15758 1. The empty initializer list is written as `{}` which is exactly an empty
|
|
ferencd@0
|
15759 JSON object.
|
|
ferencd@0
|
15760 2. C++ has no way of describing mapped types other than to list a list of
|
|
ferencd@0
|
15761 pairs. As JSON requires that keys must be of type string, rule 2 is the
|
|
ferencd@0
|
15762 weakest constraint one can pose on initializer lists to interpret them
|
|
ferencd@0
|
15763 as an object.
|
|
ferencd@0
|
15764 3. In all other cases, the initializer list could not be interpreted as
|
|
ferencd@0
|
15765 JSON object type, so interpreting it as JSON array type is safe.
|
|
ferencd@0
|
15766
|
|
ferencd@0
|
15767 With the rules described above, the following JSON values cannot be
|
|
ferencd@0
|
15768 expressed by an initializer list:
|
|
ferencd@0
|
15769
|
|
ferencd@0
|
15770 - the empty array (`[]`): use @ref array(initializer_list_t)
|
|
ferencd@0
|
15771 with an empty initializer list in this case
|
|
ferencd@0
|
15772 - arrays whose elements satisfy rule 2: use @ref
|
|
ferencd@0
|
15773 array(initializer_list_t) with the same initializer list
|
|
ferencd@0
|
15774 in this case
|
|
ferencd@0
|
15775
|
|
ferencd@0
|
15776 @note When used without parentheses around an empty initializer list, @ref
|
|
ferencd@0
|
15777 basic_json() is called instead of this function, yielding the JSON null
|
|
ferencd@0
|
15778 value.
|
|
ferencd@0
|
15779
|
|
ferencd@0
|
15780 @param[in] init initializer list with JSON values
|
|

|
|
ferencd@0
|
15782 @param[in] type_deduction internal parameter; when set to `true`, the type
|
|
ferencd@0
|
15783 of the JSON value is deducted from the initializer list @a init; when set
|
|
ferencd@0
|
15784 to `false`, the type provided via @a manual_type is forced. This mode is
|
|
ferencd@0
|
15785 used by the functions @ref array(initializer_list_t) and
|
|
ferencd@0
|
15786 @ref object(initializer_list_t).
|
|
ferencd@0
|
15787

|

ferencd@0
|
15790 value_t::array and @ref value_t::object are valid); when @a type_deduction
|

|
|
ferencd@0
|
15795 whose first element is a string. In this case, the constructor could not
|
|
ferencd@0
|
15796 create an object. If @a type_deduction would have be `true`, an array
|
|
ferencd@0

15797 would have been created. See @ref object(initializer_list_t)

|
22358 The merge patch format is primarily intended for use with the HTTP PATCH
|
|
ferencd@0
|
22359 method as a means of describing a set of modifications to a target
|
|
ferencd@0
|
22360 resource's content. This function applies a merge patch to the current
|
|
ferencd@0
|
22361 JSON value.
|
|
ferencd@0
|
22362
|
|
ferencd@0
|
22363 The function implements the following algorithm from Section 2 of
|
|
ferencd@0
|
22364 [RFC 7396 (JSON Merge Patch)](https://tools.ietf.org/html/rfc7396):

|

|

ferencd@0

22371 for each Name/Value pair in Patch:
|
|
ferencd@0

22372 if Value is null:
|
|
ferencd@0

22373 if Name exists in Target:
