refSee the current Perl documentation for ref. Here is our local, out-dated (pre-5.6) version: ref - find out the type of thing being referenced
ref EXPR ref
Returns a
TRUE value if
EXPR is a reference,
FALSE otherwise. If
EXPR is not specified,
REF SCALAR ARRAY HASH CODE GLOB
If the referenced object has been blessed into a package, then that package
name is returned instead. You can think of ref() as a
if (ref($r) eq "HASH") { print "r is a reference to a hash.\n"; } if (!ref($r)) { print "r is not a reference at all.\n"; } See also the perlref manpage. |
