can auto save "Set" property when saving a object?

for example:

Set authorities = new CopyOnWriteArraySet();
for (int i=0; i<model.getRoles().length; i++) {
AuthoritiesId authoritiesId = new AuthoritiesId();
authoritiesId.setUserDetails(userDetails);
authoritiesId.setRoleDefiniens(roleDefiniensDao.loadByPrimaryKey(model.getRoles()[i]));
Authorities authority = new Authorities(authoritiesId);

authorities.add(authority);
}
userDetails.setSetOfAuthorities(authorities);

session.save(userDetails);

I've tried. I used method saveOrUpdate.

It seems it can save a new Object in Set

but it can't delete Object. if I removed it from the Set
