Gibson, Architect" | Is there a way in CLOS to get a list of all instances from the class object | of which the instances are members? no, but some Common Lisp implementations provide access to heap walkers from their memory management subsystems that return a list of all "live" objects of a particular system type. STANDARD-INSTANCE is typically such a system type, but you can easily test for the correct classness yourself. which Common Lisp are you using? #:Erik -- @1999-07-22T00:37:33Z -- pi billion seconds since the turn of the century
