[18] abstract class ModelledEnum{
[19] /** @var static[] /
[20] private static $pool = [];
[21]
[22] /* @var int /
[23] private $id;
[24] /* @var string */
[25] private $name;
[26]
[27] protected static function addEnumEntry(static $entry){
[28] self::$pool[$entry->getId()] = $entry;
[29] }
[30]
[31] public static function get($id){
[32] return isset(self::$pool[$id]) ? clone self::$pool[$id] : null;
[33] }
[34]
[35] public static function getByName($name){
[36] foreach(self::$pool as $element){
[37] if($element->getName() === $name){
