get a (pointer) value (explicit)

Performs explicit type conversion between the JSON value and a compatible value if required.

• If the requested type is a pointer to the internally stored JSON value that pointer is returned. No copies are made.
• If the requested type is the current basic_json, or a different basic_json convertible from the current basic_json.
• Otherwise the value is converted by calling the json_serializer<ValueType> from_json() method.

Template Parameters

ValueTypeCV	the provided value type
ValueType	the returned value type

Returns

copy of the JSON value, converted to

Template Parameters

ValueType

if necessary

Exceptions

what	json_serializer<ValueType> from_json() method throws if conversion is required

inlinenoexcept

get a pointer value (explicit)

Explicit pointer access to the internally stored JSON value. No copies are made.

Warning

The pointer becomes invalid if the underlying JSON object changes.

Template Parameters

PointerType

pointer type; must be a pointer to array_t, object_t, string_t, boolean_t, number_integer_t, number_unsigned_t, or number_float_t.

Returns

pointer to the internally stored JSON value if the requested pointer type PointerType fits to the JSON value; nullptr otherwise

@complexity Constant.

@liveexample{The example below shows how pointers to internal values of a JSON value can be requested. Note that no type conversions are made and a nullptr is returned if the value and the requested pointer type does not match.,get__PointerType}

get a value (implicit)

Implicit type conversion between the JSON value and a compatible value. The call is realized by calling get() const.

Template Parameters

ValueType

non-pointer type compatible to the JSON value, for instance int for JSON integer numbers, bool for JSON booleans, or std::vector types for JSON arrays. The character type of string_t as well as an initializer list of this type is excluded to avoid ambiguities as these types implicitly convert to std::string.

Returns

copy of the JSON value, converted to type ValueType

Exceptions

type_error.302

in case passed type ValueType is incompatible to the JSON value type (e.g., the JSON value is of type boolean, but a string is requested); see example below

@complexity Linear in the size of the JSON value.

@liveexample{The example below shows several conversions from JSON values to other types. There a few things to note: (1) Floating-point numbers can be converted to integers\, (2) A JSON array can be converted to a standard std::vector<short>\, (3) A JSON object can be converted to C++ associative containers such as std::unordered_map<std::string\, json>.,operator__ValueType}
