void nlohmann::basic_json::insert | ( | const_iterator | first,
|  | const_iterator | last
| ) |  |
| inline
  Inserts elements from range `[first, last)`. Parameters
  [in] | first | begin of the range of elements to insert
  [in] | last | end of the range of elements to insert
  Exceptions
  type_error.309 | if called on JSON values other than objects; example: `"cannot use insert() with string"`
  invalid_iterator.202 | if iterator first or last does does not point to an object; example: `"iterators first and last must point to objects"`
  invalid_iterator.210 | if first and last do not belong to the same JSON value; example: `"iterators do not fit"`
  Complexity Logarithmic: `O(N*log(size() + N))`, where `N` is the number of elements to insert. Example The example shows how `insert()` is used. 1 #include "json.hpp" 2 3 using json = nlohmann::json; 4 5 int main() 6 { 7 // create two JSON objects 8 json j1 = {{"one", "eins"}, {"two", "zwei"}}; 9 json j2 = {{"eleven", "elf"}, {"seventeen", "siebzehn"}}; 10 11 // output objects 12 std::cout << j1 << '\n'; 13 std::cout << j2 << '\n'; 14 15 // insert range from j2 to j1 16 j1.insert(j2.begin(), j2.end()); 17 18 // output result of insert call 19 std::cout << j1 << '\n'; 20 } nlohmann::json basic_json<> json default JSON class Definition: json.hpp:13933 Output (play with this example online):
      {"one":"eins","two":"zwei"}
      {"eleven":"elf","seventeen":"siebzehn"}
      {"eleven":"elf","one":"eins","seventeen":"siebzehn","two":"zwei"}
  The example code above can be translated with
      g++ -std=c++11 -Isrc doc/examples/insert__range_object.cpp -o insert__range_object
