operator/ [3/3] template<typename BasicJsonType > json_pointer operator/ ( const json_pointer< BasicJsonType > &  ptr, std::size_t  array_index  ) friend Parameters [in] ptr JSON pointer [in] array_index array index Returns a new JSON pointer with array_index appended to ptr Example The example shows the usage of operator/. #include <iostream> #include <nlohmann/json.hpp> using json = nlohmann::json; int main() { // create a JSON pointer json::json_pointer ptr("/foo"); // apppend a JSON Pointer std::cout << ptr / json::json_pointer("/bar/baz") << '\n'; // append a string std::cout << ptr / "fob" << '\n'; // append an array index std::cout << ptr / 42 << std::endl; } Output (play with this example online): "/foo/bar/baz" "/foo/fob" "/foo/42" The example code above can be translated with g++ -std=c++11 -Isingle_include doc/examples/json_pointer__operator_add_binary.cpp -o json_pointer__operator_add_binary Complexity Linear in the length of ptr.
