NAME
Acme::Damn - 'Unbless' Perl objects.
SYNOPSIS
use Acme::Damn; my $ref = ... some reference ... my $obj = bless $ref , 'Some::Class'; ... do something with your object ... $ref = damn $obj; # recover the original reference (unblessed) ... neither $ref nor $obj are Some::Class objects ...
DESCRIPTION
Acme::Damn provides a single routine, damn(), which takes a blessed reference (a Perl object), and unblesses it, to return the original reference.
EXPORT
By default, Acme::Damn exports the method damn() into the current namespace. Aliases for damn() (see below) may be imported upon request.
Methods
- damn object
-
damn() accepts a single blessed reference as its argument, and returns that reference unblessed. If object is not a blessed reference, then damn() will
die
with an error. - bless reference
- bless reference [ , package ]
- bless reference [ , undef ]
-
Optionally, Acme::Damn will modify the behaviour of
bless
to allow the passing of an explicitundef
as the target package to invoke damn():use Acme::Damn qw( bless ); my $obj = ... some blessed reference ...; # the following statements are equivalent my $ref = bless $obj , undef; my $ref = damn $obj;
NOTE: The modification of
bless
is lexically scoped to the current package, and is not global.
Method Aliases
Not everyone likes to damn the same way or in the same language, so Acme::Damn offers the ability to specify any alias on import, provided that alias is a valid Perl subroutine name (i.e. all characters match
\w
).use Acme::Damn qw( unbless ); use Acme::Damn qw( foo ); use Acme::Damn qw( unblessthyself ); use Acme::Damn qw( recant );
Version 0.02 supported a defined list of aliases, and this has been replaced in v0.03 by the ability to import any alias for
damn()
.WARNING
Just as
bless
doesn't call an object's initialisation code,damn
doesn't invoke an object'sDESTROY
method. For objects that need to beDESTROY
ed, either don'tdamn
them, or callDESTROY
before judgement is passed.ACKNOWLEDGEMENTS
Thanks to Claes Jacobsson <claes@surfar.nu> for suggesting the use of aliases, and Bo Lindbergh <blgl@cpan.org> for the suggested modification of
bless
