SUMOSAXAttributes attrs; // Add some attributes to the set attrs.addAttribute("name", "John"); attrs.addAttribute("age", "25"); // Check if the "name" attribute is present if (attrs.hasAttribute("name")) { std::cout << "Name: " << attrs.getValue("name") << std::endl; }In this example, we have created a SUMOSAXAttributes object and added two attributes "name" and "age" to it. We then use the hasAttribute method to check if the "name" attribute is present in the set. If it is, we print its value to the console. The SUMO library is a package library that provides tools for simulating and analyzing urban traffic systems.
