489 simple-vector
simple-vector &optional ( size '. ) Type Specifier
simple-vector is the type specifier symbol for the Lisp data structure of
that name.
The type simple-vector is a subtype of the types:
vector
(vector t)
Note: Although string is a subtype of vector, simple-string is not a subtype
of simple-vector.
The types simple-vector, simple-string, and simple-bit-vector are disjoint
subtypes of the type simple-array: simple-vector means (simpl e-array t
(*»; simple-string means (si mpl e-array stri ng-char) or (simpl e-array
character); simple-bit-vector means (si mpl e-array bi t (*».
This type specifier can be used in either symbol or list form. Used in list
form, simple-vector defines the set of specialized one-dimensional arrays of
size size. This is the same as (vector t size), except that it additionally
specifies that its elements are simple general vectors.
Examples:
(typep #(13 3 B) Jsimple-vector) => T
(subtypep Jsimple-vector Jvector) => T and T
(sys:type-arglist Jsimple-vector) => (&OPTIONAL (SIZE J*»
(simple-vector-p #(a b c»
=> T
(typep #(1 1 2) J(simple-vector 3»
=> T
and T

I
simple-vector-p object Function
Tests whether the given object is a simple general vector. A simple
general vector is a one-dimensional array whose elements have no type constraints;
the array is not displaced to another array and has no fill pointer.
See the type specifier simple-vector, page 489.
