Transform

Make-transform

Basic constructor macro for transform structures.

Syntax

(make-transform [:new-function-name <new-function-name>] 
                [:old-function-name <old-function-name>] 
                [:transform-name <transform-name>] 
                [:arguments <arguments>])

This is the usual way to construct transform structures. It simply conses together a structure with the specified fields.

This macro generates a new transform structure from scratch. See also change-transform, which can "change" an existing structure, instead.

Definition

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

Macro: make-transform

(defmacro make-transform (&rest args)
  (std::make-aggregate 'transform
                       args
                       '((:new-function-name)
                         (:old-function-name)
                         (:transform-name)
                         (:arguments))
                       'make-transform
                       nil))

Function: transform

(defun transform (new-function-name old-function-name
