15.2.3 vector | 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. See Also: 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 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. Allegro CL Implementation Details: None.
