Is there any ability in ZODB to retroactively wrap objects in a
persistence mechanism instead of having to rewrite an entire library
to use the Persistent class?
You can always persist (almost) any object, even if it does not subclass
from Persistent. However, any changes to the object will not be detected
automatically and you would have to either a) reassign the object to the
ZODB or b) mark it as changed using _p_changed()
The "it" above may be misleading:
It is very unlikely that a non-persistent object has a "_p_changed"
method.
The "it" above therefore cannot refer to the 'object not derived
from "Persistent"'.
Usually, "it" refers to the persistent parent containing the
non persistent object as attribute value.
Yes. Actually I even meant the wrong "it". I tried to clarify in a later
posting ... sorry for the confusion.
