entity.delete()
requires an entity to be "active", dao.delete(entity)
works for all entities.
There are no cascading deletes in greenDAO, you got to delete entities individually.
题
First question is, when does greenDao generate a delete function for a entity? And what's the difference between calling the entity.delete()
and the session.getEntityDao.delete(entity)
?
Second, if I delete a parent entity with a child that has ToOne relation to the parent, I have to remove the child by myself, don't I? Actually no automatic dependency "cleaning" is done, is that right?
