This module 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:
|
||
|
|
|
||
|
|
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.
