Thank you both Mike and Bryan!

Yes, I though about that, but the persistent objects should also have
this sort of ID. But then I need a database stored counter to avoid that
the objectID starts from 0 on every new program start. And so the
database generated ID would make this job.

This sort of code works fine. The problem is that it only works with
persistent objects...
Hmmh,
through the discussion I think I should NOT use the ID's!
So if the following is true under ALL circumstances (get the objects
from different context or sth.) then I am satisfied:
if "obj1 == obj2" then "pk(obj1) == pk(obj2)"
AND if "pk(obj1) == pk(obj2)" then "obj1 == obj2".
I think the first line is always true, what about the second?
Then I can create a SimilarEntry which holds a TimeInterval and
"overloads" the equals method by comparing by the pointers ("obj1 ==
obj2") and do not need the ID's.
Thank you,
Peter Karich.
