NAME
Clone - recursively copy Perl datatypes SYNOPSIS
package Foo; use parent 'Clone'; package main; my $original = Foo->new; $copy = $original->clone; # or use Clone qw(clone); $a = { 'foo' => 'bar', 'move' => 'zig' }; $b = [ 'alpha', 'beta', 'gamma', 'vlissides' ]; $c = Foo->new; $d = clone($a); $e = clone($b); $f = clone($c); DESCRIPTION
This module provides a clone() method which makes recursive copies of nested hash, array, scalar and reference types, including tied variables and objects. clone() takes a scalar argument and duplicates it. To duplicate lists, arrays or hashes, pass them in by reference. e.g. my $copy = clone (@array); # or my %copy = %{ clone (\%hash) }; SEE ALSO
Storable's dclone() is a flexible solution for cloning variables, albeit slower for average-sized data structures. Simple and naive benchmarks show that Clone is faster for data structures with 3 or less levels, while dclone() can be faster for structures 4 or more levels deep. COPYRIGHT
