Ubdd/level

Change-ubdd/level

Modifying constructor for ubdd/level structures.

Syntax

(change-ubdd/level x 
                   [:ubdd <ubdd>] 
                   [:level <level>])

This is an often useful alternative to make-ubdd/level.

We construct a new ubdd/level 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.
