ANSI Common Lisp  15 Arrays 15.2 Dictionary of Arrays

System Class |
- Class Precedence List:
-
vector,
array,
sequence,
t
- Description:
-
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:
-
Specializing.
- 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 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.

- Notes:
-
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.
