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. #include <iostream> #include <nlohmann/json.hpp> using json = nlohmann::json; int main() { // different JSON Pointers json::json_pointer ptr1(""); json::json_pointer ptr2("/foo"); json::json_pointer ptr3("/foo/0"); json::json_pointer ptr4("/"); json::json_pointer ptr5("/a~1b"); json::json_pointer ptr6("/c%d"); json::json_pointer ptr7("/e^f"); json::json_pointer ptr8("/g|h"); json::json_pointer ptr9("/i\\j"); json::json_pointer ptr10("/k\"l"); json::json_pointer ptr11("/ "); json::json_pointer ptr12("/m~0n"); std::cout << ptr1.to_string() << '\n' << ptr2.to_string() << '\n' << ptr3.to_string() << '\n' << ptr4.to_string() << '\n' << ptr5.to_string() << '\n' << ptr6.to_string() << '\n' << ptr7.to_string() << '\n' << ptr8.to_string() << '\n' << ptr9.to_string() << '\n' << ptr10.to_string() << '\n' << ptr11.to_string() << '\n' << ptr12.to_string() << std::endl; } Output (play with this example online): /foo /foo/0 / /a~1b /c%d /e^f /g|h /i\j /k"l / /m~0n The example code above can be translated with g++ -std=c++11 -Isingle_include doc/examples/json_pointer__to_string.cpp -o json_pointer__to_string Since version 2.0.0 Definition at line 8473 of file json.hpp.
