JSON for Modern C++  3.7.0

◆ to_string()

template<typename BasicJsonType >
std::string nlohmann::json_pointer< BasicJsonType >::to_string ( ) const
inline
Invariant
For each JSON pointer ptr, it holds:
ptr == json_pointer(ptr.to_string());
Returns
a string representation of the JSON pointer
Example
The example shows the result of to_string.
1 #include <iostream>
2 #include <nlohmann/json.hpp>
3 
4 using json = nlohmann::json;
5 
6 int main()
7 {
8  // different JSON Pointers
9  json::json_pointer ptr1("");
10  json::json_pointer ptr2("/foo");
11  json::json_pointer ptr3("/foo/0");
12  json::json_pointer ptr4("/");
13  json::json_pointer ptr5("/a~1b");
14  json::json_pointer ptr6("/c%d");
15  json::json_pointer ptr7("/e^f");
16  json::json_pointer ptr8("/g|h");
17  json::json_pointer ptr9("/i\\j");
18  json::json_pointer ptr10("/k\"l");
19  json::json_pointer ptr11("/ ");
20  json::json_pointer ptr12("/m~0n");
21 
22 
23  std::cout << ptr1.to_string() << '\n'
24  << ptr2.to_string() << '\n'
25  << ptr3.to_string() << '\n'
26  << ptr4.to_string() << '\n'
27  << ptr5.to_string() << '\n'
28  << ptr6.to_string() << '\n'
29  << ptr7.to_string() << '\n'
30  << ptr8.to_string() << '\n'
31  << ptr9.to_string() << '\n'
32  << ptr10.to_string() << '\n'
33  << ptr11.to_string() << '\n'
34  << ptr12.to_string() << std::endl;
