Jvaluex-primitive

Change-jvaluex-primitive

Modifying constructor for jvaluex-primitive structures.

Syntax

(change-jvaluex-primitive x 
                          [:get <get>])

This is an often useful alternative to make-jvaluex-primitive.

We construct a new jvaluex-primitive 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.
