json_pointer operator "" _json_pointer(const char* s, std::size_t n);
This operator implements a user-defined string literal for JSON Pointers. It can be used by adding #!cpp _json_pointer
to a string literal and returns a json_pointer
object if no parse error occurred.
Use any of the following lines to bring the operator into scope:
using namespace nlohmann::literals; using namespace nlohmann::json_literals; using namespace nlohmann::literals::json_literals; using namespace nlohmann;
Alternatively, define JSON_USE_GLOBAL_UDLS
to make them available in the global namespace.
s
(in) : a string representation of a JSON Pointer
n
(in) : length of string s
json_pointer
value parsed from s
The function can throw anything that json_pointer::json_pointer
would throw.
Linear.
??? example
The following code shows how to create JSON Pointers from string literals. ```cpp --8<-- "examples/operator_literal_json_pointer.cpp" ``` Output: ```json --8<-- "examples/operator_literal_json_pointer.output" ```
