Hi all,
Is the ODMG API supposed to delete items in a 1:n collection
automatically for you?
I saw in the FAQ that "Objects are registered to a transaction so that
on commit of
the transaction it knows that d and e do not longer belong to the
collection. the ODMG collection will not delete the objects
d and e but only the REFERENCES from the collection to those objects!".
I'm not sure exactly what is meant though by "REFERENCES" vs. the actual
object in a 1:n relationship.
I have a User object with a collection attribute for Permissions. When I
find a persisted User, and then call remove a Permission from the User
object's collection, and then commit the transaction, the related row in
the permission table is not deleted.
For example:
transaction.begin();
String removePermID = "DNLD";
User user = ... find persisted user...;
for(Iterator i = user.getPermissions().iterator(); i.hasNext;)
{
Permission perm = (Permission)i.next();
if(perm.getPermissionID().equals(removePermID)
{
user.getPermissions().remove(perm);
}
}
transaction.commit();
Am I misunderstanding how its supposed to work?
Thanks in advance,
Brian
