t
Any one-dimensional array is a vector.
The type vector
is a subtype of type array
;
for all types x
, (vector x)
is the same as (array x (*))
.
The type (vector t)
, the type string
, and the type bit-vector
are disjoint subtypes of type vector
.
Specializing.
(vector [{element-type | *} [{size | *}]])
size—a non-negative fixnum.
element-type—a type specifier.
This denotes the set of specialized vectors whose element type and dimension match the specified values. Specifically:
If element-type is the symbol *, vectors are not excluded on the basis of their element type. Otherwise, only those vectors are included whose actual array element type is the result of upgrading element-type; see Section 15.1.2.1 (Array Upgrading).
If a size is specified, the set includes only those vectors whose only dimension is size. If the symbol * is specified instead of a size, the set is not restricted on the basis of dimension.
Section 15.1.2.2 (Required Kinds of Specialized Arrays), Section 2.4.8.3 (Sharpsign Left-Parenthesis), Section 22.1.3.7 (Printing Other Vectors), Section 2.4.8.12 (Sharpsign A)
The type (vector
e s)
is equivalent to the type (array
e (
s))
.
The type (vector bit)
has the name bit-vector
.
The union of all types (vector C)
,
where C is any subtype of character
,
has the name string
.
(vector *)
refers to all vectors
regardless of element type, (vector
type-specifier)
refers only to those vectors
that can result from giving type-specifier as the
:element-type argument to make-array
.
