static basic_json nlohmann::basic_json::object | ( | std::initializer_list< basic_json > | init = `std::initializer_list<basic_json>()` | ) |
| inlinestatic
  Creates a JSON object value from a given initializer list. The initializer lists elements must be pairs, and their first elements must be strings. If the initializer list is empty, the empty object `{}` is created. Note This function is only added for symmetry reasons. In contrast to the related function array(std::initializer_list<basic_json>), there are no cases which can only be expressed by this function. That is, any initializer list init can also be passed to the initializer list constructor basic_json(std::initializer_list<basic_json>, bool, value_t). Parameters
  [in] | init | initializer list to create an object from (optional)
  Returns JSON object value Exceptions
  std::domain_error | if init is not a pair whose first elements are strings; thrown by basic_json(std::initializer_list<basic_json>, bool, value_t)
  Complexity Linear in the size of init. Example The following code shows an example for the object function. 1 #include <json.hpp> 2 3 using namespace nlohmann; 4 5 int main() 6 { 7 // create JSON objects 8 json j_no_init_list = json::object(); 9 json j_empty_init_list = json::object({}); 10 json j_list_of_pairs = json::object({ {"one", 1}, {"two", 2} }); 11 //json j_invalid_list = json::object({ "one", 1 }); // would throw 12 13 // serialize the JSON objects 14 std::cout << j_no_init_list << '\n'; 15 std::cout << j_empty_init_list << '\n'; 16 std::cout << j_list_of_pairs << '\n'; 17 } nlohmann::basic_json::object static basic_json object(std::initializer_list< basic_json > init=std::initializer_list< basic_json >()) explicitly create an object from an initializer list Definition: json.hpp:1519 nlohmann::basic_json a class to store JSON values Definition: json.hpp:191 nlohmann namespace for Niels Lohmann Definition: json.hpp:88 Output (play with this example online):
      {}
      {}
      {"one":1,"two":2}
  The example code above can be translated with
      g++ -std=c++11 -Isrc doc/examples/object.cpp -o object
