Do you mean that if 3 users fetch the same enterprise object
without changing anything, the object will only be created once (in
the "snapshot") ?
No. An object will be created in each EC, but it will have very
little _data_ in it. All the EOs that represent one physical object
share the data for that object in the snapshot until one of the
modifies it. At that point, that EO has the modified (but not yet
saved) data in it. What I am getting at is that multiple EO objects
representing the same physical object might be less memory intensive
than you are imagining.
If so, I don't need to use any shared editing context... that's
clear. But that's strange ?? When the object is deleted it means
that it's deleted in each EC
Yes, once you call saveChanges().
and when I modify the object, a second one is created
No, it is the same object. But an object is created to hold the
changed, unsaved value (e.g. a String object or an Integer object etc.).
and when I save the changes, all the objects in all the EC are
changed too ?
Yes, updated / changed depending on how you want to name it.
