set() публичный Метод

Normally this is as simple as $entity->$key = $value although more complicated transforms can happen should a field type choose to override this method. Note too that this will also be the default method called for an entity builder which is designed to receive raw data to initialise an entity.
public set ( object $entity, mixed $value )
$entity object
$value mixed
