Jstatem-ifelse

Change-jstatem-ifelse

Modifying constructor for jstatem-ifelse structures.

Syntax

(change-jstatem-ifelse x 
                       [:test <test>] 
                       [:then <then>] 
                       [:else <else>])

This is an often useful alternative to make-jstatem-ifelse.

We construct a new jstatem-ifelse 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.
