Understanding deleting and deleting relations in greenDao

Question

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?

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.

Too bad missing cascade delete – Jemshit Jun 22 '17 at 07:07
It's a complex and dangerous thing to do. You might end up deleting things you did not intent to. – Markus Junginger Jun 23 '17 at 07:59
