| 32 | Clone - recursively copy Perl datatypes | |||
| 33 | ||||
| 34 | =head1 SYNOPSIS | |||
| 35 | ||||
| 36 | use Clone; | |||
| 37 | ||||
| 38 | push @Foo::ISA, 'Clone'; | |||
| 39 | ||||
| 40 | $a = new Foo; | |||
| 41 | $b = $a->clone(); | |||
| 42 | ||||
| 43 | # or | |||
| 44 | ||||
| 45 | use Clone qw(clone); | |||
| 46 | ||||
| 47 | $a = { 'foo' => 'bar', 'move' => 'zig' }; | |||
| 48 | $b = [ 'alpha', 'beta', 'gamma', 'vlissides' ]; | |||
| 49 | $c = new Foo(); | |||
| 50 | ||||
| 51 | $d = clone($a); | |||
| 52 | $e = clone($b); | |||
| 53 | $f = clone($c); | |||
| 54 | ||||
| 55 | =head1 DESCRIPTION | |||
| 56 | ||||
| 57 | This module provides a clone() method which makes recursive | |||
| 58 | copies of nested hash, array, scalar and reference types, | |||
| 59 | including tied variables and objects. | |||
| 60 | ||||
| 61 | ||||
| 62 | clone() takes a scalar argument and an optional parameter that | |||
| 63 | can be used to limit the depth of the copy. To duplicate lists, | |||
| 64 | arrays or hashes, pass them in by reference. e.g. | |||
| 65 | ||||
| 66 | my $copy = clone (\@array); | |||
| 67 | ||||
| 68 | # or | |||
| 69 | ||||
| 70 | my %copy = %{ clone (\%hash) }; | |||
| 71 | ||||
| 72 | ||||
| 73 | For a slower, but more flexible solution see Storable's dclone(). | |||
