get() const noexcept(noexcept(std::declval<const basic_json_t &>().template get_impl<ValueType>(detail::priority_tag<4>{})));Performs explicit type conversion between the JSON value and a compatible value if required.
If the requested type is a pointer to the internally stored JSON value that pointer is returned. No copies are made.
If the requested type is the current basic_json, or a different basic_json convertible from the current basic_json.
Otherwise the value is converted by calling the json_serializer<ValueType> from_json() method.
