In this section, we describe the functions that accept both strings and vectors.
t
if object is an array (i.e., either a
vector or a string).
(arrayp [a]) => t (arrayp "asdf") => t
(setq primes [2 3 5 7 11 13]) => [2 3 5 7 11 13] (aref primes 4) => 11 (elt primes 4) => 11 (aref "abcdefg" 1) => 98 ; `b' is ASCII code 98.
See also the function elt
, in section Sequences.
(setq w [foo bar baz]) => [foo bar baz] (aset w 0 'fu) => fu w => [fu bar baz] (setq x "asdfasfd") => "asdfasfd" (aset x 3 ?Z) => 90 x => "asdZasfd"
If array is a string and object is not a character, a
wrong-type-argument
error results.
(setq a [a b c d e f g]) => [a b c d e f g] (fillarray a 0) => [0 0 0 0 0 0 0] a => [0 0 0 0 0 0 0] (setq s "When in the course") => "When in the course" (fillarray s ?-) => "------------------"
If array is a string and object is not a character, a
wrong-type-argument
error results.
The general sequence functions copy-sequence
and length
are often useful for objects known to be arrays. See section Sequences.
