Example check function

function check($obj)
{
    $arc = new \AEngine\Annotations\AnnotatedReflectionClass($obj);

    foreach ($arc->getProperties() as $property) {
        $annotation = $property->getAnnotation(Enum::class);

        if ($annotation) {
            if (!$annotation->validate($property->getValue($obj))) {
                throw new RuntimeException(sprintf($annotation->getMessage(), $property->getName()));
            }
        }
    }

    return true;
}

Entity example

class Car
{
    /**
     * @Enum({'bmw', 'opel', 'lada'}, message="Value in "%s" is not available")
     *
     * @var string
     */
    public $brand;

    /**

$car = new Car();
$car->brand = 'BMW';
$car->model = 'X5';

if (check($car) === true) {
    // other code
