◆ 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());
json_pointer(const std::string &s="")
create JSON pointer
Definition: json.hpp:12502
Returns
a string representation of the JSON pointer
Example
The example shows the result of to_string.
