Hello,
I did some reading through the mailing list archives and the Elephant
manual, but cannot find a recommended way of counting the number of
persistent objects of a particular class.
I have a method that works (using map-class) but this is way too slow
for my purposes.
I did find some postin
Apologies, my mistake - late night; got POSTMODERN and can now

Hi,
I just got the latest Elephant from darcs as specified at the top of
http://common-lisp.net/project/elephant/downloads.html
I'm trying to use postmodern and am using the code in /tests as guidance
since I can't find any documentation on using postmodern. Unless I'm
mistaken, the ele-postmoder
Hi all,
How can I determine what persistent class objects exist in a store?
>From the API documentation for persistent classes I notice all the
functions require passing of a class, but let's say I don't know what
persistent classes have been stored.
Any suggestions?

Hi Robert,
I also haven't received a reply.
I agree with your thoughts below, particularly because Elephant is
designed such that you can swap out the back-end if need be.

Ian, when are objects that are instanced from persistent classes saved?
I simply call (make-instance) on the following class definition:

Hi -
I have a persistent class (i.e. :metaclass persistent-metaclass) defined
and am adding a whole bunch of objects that are instances of this class
to the root of my Elephant store.
In order to retrieve a list of them I do:
(map-class fn 'my-class-name)
My question is:
Currently I'm us

Hi,
I've noticed that when I call (open-store *my-storage*), then (close-store),
then (open-store *my-storage*) again, my LISP simply hangs.
From within SLIME/Emacs I don't get any feedback but when I run directly in
SBCL I get the following error message after the 2nd (open-store):
