std::string nlohmann::basic_json< ObjectType, ArrayType, StringType, BooleanType, NumberIntegerType, NumberUnsignedType, NumberFloatType, AllocatorType, JSONSerializer >::json_pointer::to_string ( ) const

inlinenoexcept

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 <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
