libclone-pp-perl

module to recursively copy Perl datatypes

Description

Clone::PP provides a general-purpose clone function to make deep copies of Perl data structures. It calls itself recursively to copy nested hash, array, scalar and reference types, including tied variables and objects.

The clone() function takes a scalar argument to copy. To duplicate arrays or hashes, pass them in by reference:

 my $copy = clone(\@array); my @copy = @{ clone(\@array) };
 my $copy = clone(\%hash); my %copy = %{ clone(\%hash) };

The clone() function also accepts an optional second parameter that can be used to limit the depth of the copy. If you pass a limit of 0, clone will return the same value you supplied; for a limit of 1, a shallow copy is constructed; for a limit of 2, two layers of copying are done, and so on.

This is a pure-perl implementation. For a faster XS-/C-based implementation see the libclone-perl package.
