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 elments 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 basic_json 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.
  #include <json.hpp>
  using namespace nlohmann;
  int main()
  {
  // create JSON arrays
  json j_no_init_list = json::object();
  json j_empty_init_list = json::object({});
  json j_list_of_pairs = json::object({ {"one", 1}, {"two", 2} });
  //json j_invalid_list = json::object({ "one", 1 }); // would throw
  // serialize the JSON arrays
  std::cout << j_no_init_list << '\n';
  std::cout << j_empty_init_list << '\n';
  std::cout << j_list_of_pairs << '\n';
  }
