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 ...
INSTALLATION
To install this module type the following:
perl Makefile.PL
make
make test
make install
Acme::Damn uses XS to access the internals of Perl for it's magic, and
therefore must be compiled to be installed. Also, for testing,
Acme::Damn relies on Test::More and Test::Exception.
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 explicit "undef" 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'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 <claesjac@cpan.org> for suggesting the use of
aliases, and Bo Lindbergh <blgl@cpan.org> for the suggested modification
of "bless".
