Regaccess

Change-regaccess

Modifying constructor for regaccess structures.

Syntax

(change-regaccess x 
                  [:base <base>] 
                  [:comps <comps>])

This is an often useful alternative to make-regaccess.

We construct a new regaccess structure that is a copy of x, except that you can explicitly change some particular fields. Any fields you don't mention just keep their values from x.

Definition

This is an ordinary change- macro introduced by fty::defprod.

Macro: change-regaccess

                           (:comps . regaccess->comps))
                         'change-regaccess
                         'nil))
