What is the function of get_url_data ()

What is the function of the get_url_data () code? what he does? I searched in php.net and found nothing, just about meta tag.

public function __construct () { 
 // Obtém os valores do controlador, ação e parâmetros da URL.
 // E configura as propriedades da classe.
 $this->get_url_data();
