a unique object representative of an EO?

Hello there,

I would need an unique object representative of an EO. The object needs to be identical for all EO clones of all editing contexts.

Such a _value_ representation would be the primary key or GID; but these, far as I know, ensure only isEqual for same EO, not ==. I need the identity -- namely, for Java-level locking; the intended usage is something like

===
synchronized (representative(eo)) {
  ... this code never runs concurrently for given EO, regardless of its editing context ...
}
===

Is there such an object in EOF, or do I have to create a dictionary keyed by GID or PK? The latter is simple to create, but it is sort of difficult to know when to remove the pair from there.

Thanks,
OC
