Is there a simple way to encapsulate all instance variables of an eo

By default, EO classes derive from EOGenericRecord whose instance
variables are private, including the dictionary that stores property
values. EOGenericRecord's snapshot() method will return a dictionary
of EO property values which could be serialized into an NSData object
by NSPropertyListSerialization.dataFromPropertyList(). Is this what
you mean?
I am not sure yet... I want to use NSDocument inside Cocoa/EO. The
natural way to "load" an nsdoc, is by passing to it an nsdata and a
type. So I want to init the doc with an eo, but I have to be able to
"read-back" the variables of the eo from the nsdata.
The hint sounds good to me, ...then I will have to "deserialize" right?
Other cuestion (i'd never used snapshot); does this dictionary includes
ALL variables? I mean, do I nead to mark the atribute with the "dimond"
in EOModeler in order to see it?
Thanks in advance!
