Hello there,
is there an object whose _instance_ (not just value like it seems to be with the global ID) would consistently represent one EO, regardless the EC in which the EO just happens to be?
I would need to lock on an EO, but I would need that it worked over all ECs, i.e.
===
synchronized (eo) {
// no two threads would get there with same EO
// _not even if the EO is in different ECs_
// which is why 'synchronized (eo)' does not work
}
===
Of course, I could make a thread-safe map, insert lock objects there and use globalids for index, but it seems to me rather convoluted -- not speaking of that I would not really know when to flush the data (unless I override EOs finalize, ick...)
Isn't there a better solution?
Thanks a lot,
OC
