Jexpr-instanceof

Make-jexpr-instanceof

Basic constructor macro for jexpr-instanceof structures.

Syntax

(make-jexpr-instanceof [:left <left>] 
                       [:right <right>])

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

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

Definition

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

Macro: make-jexpr-instanceof

(defmacro make-jexpr-instanceof (&rest args)
  (std::make-aggregate 'jexpr-instanceof
                       args '((:left) (:right))
                       'make-jexpr-instanceof
                       nil))

Function: jexpr-instanceof

(defun jexpr-instanceof (left right)
  (declare (xargs :guard (and (jexprp left) (jtypep right))))
  (declare (xargs :guard t))
  (let ((__function__ 'jexpr-instanceof))
    (declare (ignorable __function__))
    (b* ((left (mbe :logic (jexpr-fix left)
                    :exec left))
         (right (mbe :logic (jtype-fix right)
                     :exec right)))
      (cons :instanceof (list left right)))))
