SYNOPSIS

9         use Clone;
10
11         push @Foo::ISA, 'Clone';
12
13         $a = new Foo;
14         $b = $a->clone();
15
16         # or
17
18         use Clone qw(clone);
19
20         $a = { 'foo' => 'bar', 'move' => 'zig' };
21         $b = [ 'alpha', 'beta', 'gamma', 'vlissides' ];
22         $c = new Foo();
23
24         $d = clone($a);
25         $e = clone($b);
26         $f = clone($c);

DESCRIPTION

29       This module provides a clone() method which makes recursive copies of
30       nested hash, array, scalar and reference types, including tied vari‐
31       ables and objects.
32
33       clone() takes a scalar argument and an optional parameter that can be
34       used to limit the depth of the copy. To duplicate lists, arrays or
35       hashes, pass them in by reference. e.g.
36
37           my $copy = clone (\@array);
38
39           # or
40
41           my %copy = %{ clone (\%hash) };
42
43       For a slower, but more flexible solution see Storable's dclone().
