如何在Zend框架中设计域层对象来表示多个对象和单个对象？

class DomainObject
{
    private $singleObject;
    private $multipleObjects;

    public function __construct($singleObject, $multipleObjects)
    {
        $this->singleObject = $singleObject;
        $this->multipleObjects = $multipleObjects;
    }

    public function getSingleObject()
    {
        return $this->singleObject;
    }

    public function setSingleObject($singleObject)
    {
        $this->singleObject = $singleObject;
    }

    public function getMultipleObjects()
    {
        return $this->multipleObjects;
    }

    public function setMultipleObjects($multipleObjects)
    {
        $this->multipleObjects = $multipleObjects;
    }
}

$singleObject = new SingleObject();
$multipleObjects = [new MultipleObject1(), new MultipleObject2()];

$domainObject = new DomainObject($singleObject, $multipleObjects);

$singleObject = $domainObject->getSingleObject();
$multipleObjects = $domainObject->getMultipleObjects();
