JSON for Modern C++  3.7.0

◆ operator/=() [1/3]

template<typename BasicJsonType >
json_pointer& nlohmann::json_pointer< BasicJsonType >::operator/= ( const json_pointer< BasicJsonType > &  ptr)
inline
Parameters
[in]ptrJSON pointer to append
Returns
JSON pointer with ptr 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  // apppend 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 }
basic_json<> json
default JSON class
Definition: json.hpp:2355
::nlohmann::json_pointer< basic_json > json_pointer
JSON Pointer, see nlohmann::json_pointer.
Definition: json.hpp:14616

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
g++ -std=c++11 -Isingle_include doc/examples/json_pointer__operator_add.cpp -o json_pointer__operator_add 
Complexity
Linear in the length of ptr.
