System Class VECTOR

Class Precedence List:

vector, array, sequence, 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.

Compound Type Specifier Kind:


Compound Type Specifier Syntax:

vector [{element-type | *} [{size | *}]]

Compound Type Specifier Arguments:

size---a non-negative fixnum.

element-type---a type specifier.

Compound Type Specifier Description:

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 (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.

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.
