NAME

Package::Reaper - pseudo-garbage-collection for packages

VERSION

version 0.103

SYNOPSIS

     use Package::Generator;
     use Package::Reaper;
 
     {
       my $package = Package::Generator->new_package;
       my $reaper  = Package::Reaper->new($package);
       ...
     }
 
     # at this point, $package stash has been deleted

DESCRIPTION

This module allows you to create simple objects which, when destroyed, delete a given package. This lets you approximate lexically scoped packages.

INTERFACE

new

   my $reaper = Package::Reaper->new($package);

This returns the newly generated package reaper. When the reaper goes out of scope and is garbage collected, it will delete the symbol table entry for the package.

package

   my $package = $reaper->package;

This method returns the package which will be reaped.

is_armed

   if ($reaper->is_armed) { ... }

This method returns true if the reaper is armed and false otherwise. Reapers always start out armed. A disarmed reaper will not actually reap when destroyed.

disarm

   $reaper->disarm;

This method disarms the reaper, so that it will not reap the package when it is destoryed.

arm

   $reaper->arm;

This method arms the reaper, so that it will reap its package when it is destroyed. By default, new reapers are armed.
