Example
The example shows the result of push_back
for different JSON Pointers.
#include <iostream>
#include <nlohmann/json.hpp>
using json = nlohmann::json;
int main()
{
// create empty JSON Pointer
json::json_pointer ptr;
std::cout << ptr << '\n';
// call push_back()
ptr.push_back("foo");
std::cout << ptr << '\n';
ptr.push_back("0");
std::cout << ptr << '\n';
ptr.push_back("bar");
std::cout << ptr << '\n';
}
Output:
""
"/foo"
"/foo/0"
"/foo/0/bar"
