- Correctly support class reshape (when the class of serialized objects has changed).
So what do you do when an instance variable was added? Set it to nil and hope that everything will continue to work?
Of course. One might hope that the developer that added an instance variable to a system which had existing instanciated objects would provide suitable lazy initialization as needed. There is no magic.
Exactly. Read the answer I have just send.
- Serialize ANY kind of object. For the moment there is no object to our knowledge that we cannot serialize and materialize.
Really? You serialize Socket, Process, FileStream and something meaningful happens?
Again, no magic. One would hope an interface object that became detached
from it's service would know how to reattach.
Exactly. Ideally, a class will be able to implement #prepareToBeSerializer and #postMaterializationAction or stuff like that. So, what we want to provide is the infrastructure, the hooks. Then, we shoud identify those base classes that MUST have something like that like the cases pointed out by Philippe For example, the same happes with Set and Dictionaries. They have to be rehashes once they are materialized.
