Atc-arrays

Slong-array

Fixtype of (ATC's model of) arrays of type signed long.

This is a product type introduced by fty::defprod.

Fields

elemtype — type
elements — slong-list

Additional Requirements

The following invariant is enforced on the fields:

(and (type-case elemtype :slong) (consp elements))

Theorem: slong-arrayp-alt-def

(defthm slong-arrayp-alt-def
  (equal (slong-arrayp x)
         (and (valuep x)
              (value-case x :array)
              (equal (value-array->elemtype x)
                     (type-slong))
              (slong-listp (value-array->elements x)))))

Theorem: slong-array->elements-alt-def

(defthm slong-array->elements-alt-def
  (implies (slong-arrayp array)
           (equal (slong-array->elements array)
                  (value-array->elements array))))
