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 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 <claes@surfar.nu> for suggesting the use of
aliases, and Bo Lindbergh <blgl@cpan.org> for the suggested modification
of "bless".
