iterator nlohmann::basic_json::insert | ( | const_iterator | pos,
|  | const basic_json & | val
| ) |  |
| inline
  Inserts element val before iterator pos. Parameters
  [in] | pos | iterator before which the content will be inserted; may be the end() iterator
  [in] | val | element to insert
  Returns iterator pointing to the inserted val. Exceptions
  type_error.309 | if called on JSON values other than arrays; example: `"cannot use insert() with string"`
  invalid_iterator.202 | if pos is not an iterator of *this; example: `"iterator does not fit current value"`
  Complexity Constant plus linear in the distance between pos and end of the container. Example The example shows how `insert()` is used. 1 #include <iostream> 2 #include <nlohmann/json.hpp> 3 4 using json = nlohmann::json; 5 6 int main() 7 { 8 // create a JSON array 9 json v = {1, 2, 3, 4}; 10 11 // insert number 10 before number 3 12 auto new_pos = v.insert(v.begin() + 2, 10); 13 14 // output new array and result of insert call 15 std::cout << *new_pos << '\n'; 16 std::cout << v << '\n'; 17 } Output (play with this example online):
      10
      [1,2,10,3,4]
  The example code above can be translated with
      g++ -std=c++11 -Isingle_include doc/examples/insert.cpp -o insert
