   1 # <small>nlohmann::json_pointer::</small>operator/=
   2
   3 ```cpp
   4 // (1)
   5 json_pointer& operator/=(const json_pointer& ptr);
   6
   7 // (2)
   8 json_pointer& operator/=(std::string token);
   9
  10 // (3)
  11 json_pointer& operator/=(std::size_t array_idx)
  12 ```
  13
  14 1. append another JSON pointer at the end of this JSON pointer
  15 2. append an unescaped reference token at the end of this JSON pointer
  16 3. append an array index at the end of this JSON pointer
  17
  18 ## Parameters
  19
  20 `ptr` (in)
  21 :    JSON pointer to append
  22
  23 `token` (in)
  24 :    reference token to append
  25
  26 `array_idx` (in)
  27 :    array index to append
  28
  29 ## Return value
  30
  31 1. JSON pointer with `ptr` appended
  32 2. JSON pointer with `token` appended without escaping `token`
  33 3. JSON pointer with `array_idx` appended
  34
  35 ## Complexity
  36
  37 1. Linear in the length of `ptr`.
  38 2. Amortized constant.
  39 3. Amortized constant.
