void nlohmann::basic_json::swap | ( | object_t & | other | ) |
| inline
  Exchanges the contents of a JSON object with those of other. Does not invoke any move, copy, or swap operations on individual elements. All iterators and references remain valid. The past-the-end iterator is invalidated. Parameters
  [in,out] | other | object to exchange the contents with
  Exceptions
  std::domain_error | when JSON value is not an object; example: `"cannot use swap() with string"`
  Complexity Constant. Example The example below shows how JSON values can be swapped. 1 #include <json.hpp> 2 3 using namespace nlohmann; 4 5 int main() 6 { 7 // create a JSON value 8 json value = { {"translation", {{"one", "eins"}, {"two", "zwei"}}} }; 9 10 // create an object_t 11 json::object_t object = {{"cow", "Kuh"}, {"dog", "Hund"}}; 12 13 // swap the object stored in the JSON value 14 value["translation"].swap(object); 15 16 // output the values 17 std::cout << "value = " << value << '\n'; 18 std::cout << "object = " << object << '\n'; 19 } nlohmann::basic_json a class to store JSON values Definition: json.hpp:191 nlohmann::basic_json::object_t ObjectType< StringType, basic_json, std::less< StringType >, AllocatorType< std::pair< const StringType, basic_json >>> object_t a type for an object Definition: json.hpp:350 nlohmann namespace for Niels Lohmann Definition: json.hpp:88 nlohmann::basic_json::swap void swap(reference other) noexcept( std::is_nothrow_move_constructible< value_t >::value and std::is_nothrow_move_assignable< value_t >::value and std::is_nothrow_move_constructible< json_value >::value and std::is_nothrow_move_assignable< json_value >::value ) exchanges the values Definition: json.hpp:4641 Output (play with this example online):
      value = {"translation":{"cow":"Kuh","dog":"Hund"}}
      object = {"one":"eins","two":"zwei"}
  The example code above can be translated with
      g++ -std=c++11 -Isrc doc/examples/swap__object_t.cpp -o swap__object_t
