nlohmann::json_pointer::to_string¶
string_t to_string() const;
Return a string representation of the JSON pointer.
Return value¶
A string representation of the JSON pointer
Notes¶
For each JSON pointer ptr
, it holds:
ptr == json_pointer(ptr.to_string());
Examples¶
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:
""
"/foo"
"/foo/0"
"/"
"/a~1b"
"/c%d"
"/e^f"
"/g|h"
"/i\j"
"/k"l"
"/ "
"/m~0n"
