Damn(3pm)
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, ddaammnn(()), which takes a blessed
reference (a Perl object), and unblesses it, to return the original
reference. I can't think of any reason why you might want to do this,
but just because it's of no use doesn't mean that you shouldn't be able to do it. - EXPORT
- By default, Acme::Damn exports the method ddaammnn(()) into the current namespace. Aliases for ddaammnn(()) (see below) may be imported upon request.
- Methods
- damn object
ddaammnn(()) accepts a single blessed reference as its argument, and returns that reference unblessed. If object is not a blessed reference, then ddaammnn(()) will "die" with an error.
- 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's "DESTROY" method. For objects that need to
be "DESTROY"ed, either don't "damn" them, or call "DESTROY" before
judgement is passed.
ACKNOWLEDGEMENTS
Thanks to Claes Jacobsson <claes@surfar.nu> for suggesting the use of
aliases.
