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.
