package Memoize::ExpireTest; =head1 NAME Memoize::ExpireTest - test for Memoize expiration semantics =head1 DESCRIPTION This module is just for testing expiration semantics. It's not a very good example of how to write an expiration module. If you are looking for an example, I recommend that you look at the simple example in the Memoize::Expire documentation, or at the code for Memoize::Expire itself. If you have questions, I will be happy to answer them if you send them to mjd-perl-memoize+@plover.com. =cut $VERSION = '1.03'; my %cache; sub TIEHASH { my ($pack) = @_; bless \%cache => $pack; } sub EXISTS { my ($cache, $key) = @_; exists $cache->{$key} ? 1 : 0; } sub FETCH { my ($cache, $key) = @_; $cache->{$key}; } sub STORE { my ($cache, $key, $val) = @_; $cache->{$key} = $val; } sub expire { my ($key) = @_; delete $cache{$key}; } 1;
