Examples¶

Example

The example shows the result of to_string.

#include<iostream>
#include<nlohmann/json.hpp>
usingjson=nlohmann::json;
intmain()
{
// different JSON Pointers
json::json_pointerptr1("");
json::json_pointerptr2("/foo");
json::json_pointerptr3("/foo/0");
json::json_pointerptr4("/");
json::json_pointerptr5("/a~1b");
json::json_pointerptr6("/c%d");
json::json_pointerptr7("/e^f");
json::json_pointerptr8("/g|h");
json::json_pointerptr9("/i\\j");
json::json_pointerptr10("/k\"l");
json::json_pointerptr11("/ ");
json::json_pointerptr12("/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"
