Hi Roy,
See
http://docs.doctrine-project.org/en/latest/reference/working-with-objects.html#persisting-entities
Any object that is created and that is not yet known to the ObjectManager
is "UNMANAGED" ("DETACHED" if it has an identifier)
Any object that was fetched from the ObjectManager is "MANAGED"
Any object that is persisted via the ObjectManager is "NEW"
Any object that is removed via the ObjectManager is "REMOVED"
Any object that is cleared from the ObjectManager is "DETACHED"
Flushing causes "REMOVED" instances to become "UNMANAGED"
See
https://github.com/doctrine/doctrine2/blob/f197a9c9f140a06f399fc05d7149220d04eb3a56/lib/Doctrine/ORM/UnitOfWork.php#L63-L85for
more details. You can lookup usages of those constants within the
UnitOfWork to have a better understanding of what is going on.
Cheers,
Marco Pivetta
