Is it possible to specify isName, isLimit methods in DTO?

Question

PHP

For example, is it possible to add methods isLimit, isPage to such a DTO? or is it already a valueObject?

class PaginationDTO
{
    /**
     * @var int
     */
    private $limit;

    /**
     * @var int
     */
    private $page;

    public function __construct(int $limit, int $page)
    {
        $this->limit = $limit;
        $this->page = $page;
    }

    public function getLimit(): int
    {
        return $this->limit;
    }

    public function getPage(): int
    {
        return $this->page;
    }
}

Answer 1

no longer a DTO
