Description: module to recursively copy Perl datatypes
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.
