json_pointer& nlohmann::json_pointer< BasicJsonType >::operator/= | ( | std::size_t | array_index | ) |

  Parameters
  [in] | array_index | array index to append
  Returns JSON pointer with array_index appended Example The example shows the usage of `operator/=`. 1 #include <iostream> 2 #include <nlohmann/json.hpp> 3 4 using json = nlohmann::json; 5 6 int main() 7 { 8 // create a JSON pointer 9 json::json_pointer ptr("/foo"); 10 std::cout << ptr << '\n'; 11 12 // append a JSON Pointer 13 ptr /= json::json_pointer("/bar/baz"); 14 std::cout << ptr << '\n'; 15 16 // append a string 17 ptr /= "fob"; 18 std::cout << ptr << '\n'; 19 20 // append an array index 21 ptr /= 42; 22 std::cout << ptr << std::endl; 23 } Output (play with this example online):
      "/foo"
      "/foo/bar/baz"
      "/foo/bar/baz/fob"
      "/foo/bar/baz/fob/42"
  The example code above can be translated with

Complexity Amortized constant. See also operator/=(const json_pointer&) to append a JSON pointer operator/=(std::string) to append a reference token operator/(const json_pointer&, std::string) for a binary operator Since version 3.6.0 Definition at line 10216 of file json.hpp.
