(wrt 22/5/90 PCL (REV 2) and AKCL 1.485)
I've been trying to create new method combinations using:
"define-method-combination" (long form) and the object
returned is:
#<Standard-Method PCL::FIND-METHOD-COMBINATION (PCL::GENERIC-FUNCTION
RULE T) 16050520>
(for a combination called "rule"). What I'd like to do is
have this new combination method replace the original standard
combination (by setq'ing pcl::*standard-method-combination* with this
value!?! am I an the right track?????)
If I attempt this I get the following error:
Error: When initializing the generic-function #<compiled-closure FOO>:
The :METHOD-COMBINATION initialization argument was:
#<Standard-Method PCL::FIND-METHOD-COMBINATION
(PCL::GENERIC-FUNCTION RULE T) 15710000>.
It must be a method combination object.
Error signalled by SHARED-INITIALIZE.
Broken at SHARED-INITIALIZE. Type :H for Help.
Has anyone got any pointers as to how one might replace the standard
method
combination with a user defined?
PS I known this defeats the purpose of the mail group but could any
responses
be mailed directly, as I'm not sure if the mail groups mail is getting
thro'
Thanx in advance. (nick j)
