Bitrix Framework

Objects convert values to field type. It means that values will have the value formats and string - the string formats:

$book = \Bitrix\Main\Test\Typography\BookTable::getByPrimary(1)
	->fetchObject();

var_dump($book->getId());
// prints int 1

var_dump($book->getTitle());
// prints string 'Title 1' (length=7)

Please, be advised regarding to BooleanField: expects true or false, despite the fact that database could store other values:

//(new BooleanField('IS_ARCHIVED'))
//	->configureValues('N', 'Y'),

$book = \Bitrix\Main\Test\Typography\BookTable::getByPrimary(1)
	->fetchObject();

var_dump($book->getIsArchived());
// prints boolean true

// set values are boolean as well
$book->setIsArchived(false);
