Element-option

Change-element-option

Modifying constructor for element-option structures.

Syntax

(change-element-option x 
                       [:get <get>])

This is an often useful alternative to make-element-option.

We construct a new element-option 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.

                         'nil))
