JSON for Modern C++ 3.10.3

◆ operator/ [2/3]

template<typename BasicJsonType >
json_pointer operator/ ( const json_pointer< BasicJsonType > &  ptr,
std::size_t  array_idx 
)
friend
Parameters
[in]ptrJSON pointer
[in]array_idxarray index
Returns
a new JSON pointer with array_idx appended to ptr
Example
The example shows the usage of operator/.
1#include <iostream>
2#include <nlohmann/json.hpp>
3
4using json = nlohmann::json;
5
6int main()
7{
8 // create a JSON pointer
9 json::json_pointer ptr("/foo");
10
11 // append a JSON Pointer
12 std::cout << ptr / json::json_pointer("/bar/baz") << '\n';
13
14 // append a string
15 std::cout << ptr / "fob" << '\n';
16
17 // append an array index
18 std::cout << ptr / 42 << std::endl;
19}
::nlohmann::json_pointer< basic_json > json_pointer
JSON Pointer, see nlohmann::json_pointer.
Definition: json.hpp:17726
basic_json<> json
default JSON class
Definition: json.hpp:3472

Output (play with this example online):
"/foo/bar/baz"
"/foo/fob"
"/foo/42"
The example code above can be translated with
g++ -std=c++11 -Isingle_include doc/examples/json_pointer__operator_add_binary.cpp -o json_pointer__operator_add_binary 
Complexity
Linear in the length of ptr.
