NAME

Cache::Memcached::Indexable::Logic::DigestSHA1 - a fine logic for Cache::Memcached::Indexable

SYNOPSIS

 use Cache::Memcached::Indexable::Logic::DigestSHA1;
 use Cache::Memcached::Indexable;
 
 my $logic = Cache::Memcached::Indexable::Logic::DigestSHA1->new;
 $logic->set_max_power(0xff);
 
 my $memd = Cache::Memcached::Indexable->new({
     'servers' => [ "10.0.0.15:11211", "10.0.0.15:11212",
                    "10.0.0.17:11211", [ "10.0.0.17:11211", 3 ] ],
     'debug' => 0,
     'compress_threshold' => 10_000,
 });
 
 $memd->set_logic($logic);

or

 my $memd = Cache::Memcache::Indexable->new({
     'logic' => 'Cache::Memcached::Indexable::Logic::DigestSHA1',
     'logic_args' => { set_max_power => 0xff },
     'servers' => [ "10.0.0.15:11211", "10.0.0.15:11212",
                    "10.0.0.17:11211", [ "10.0.0.17:11211", 3 ] ],

 });

DESCRIPTION

This module is a kind of logic class for Cache::Memcached::Indexable. It uses to get an original key through Digest::SHA1::sha1_hex() function with your key.

METHOD

$logic->set_max_power($power)

You can set how many patterns do you want to use for the original key. The $power must be a 16's power minus 1 (0xF, 0xFF, 0xFFF, 0xFFFF, 0xFFFFF ...).

Note that the $memd-keys()> will be taken too long time to return all your keys if you set a huge number to this method.
