NAME

Cache::Memcached::Indexable - A key indexable Cache::Memcached wrapper

SYNOPSIS

 use Cache::Memcached::Indexable;
 
 $memd = new Cache::Memcached::Indexable {
     '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,
 };
 $memd->set_servers($array_ref);
 $memd->set_compress_threshold(10_000);
 $memd->enable_compress(0);
 
 $memd->set("my_key", "Some value");
 $memd->set("object_key", { 'complex' => [ "object", 2, 4 ]});
 
 $val = $memd->get("my_key");
 $val = $memd->get("object_key");
 if ($val) { print $val->{'complex'}->[2]; }
 
 $memd->incr("key");
 $memd->decr("key");
 $memd->incr("key", 2);
 
 @all_keys = $memd->keys;

DESCRIPTION

THIS IS ALPHA SOFTWARE

Cache::Memcached::Indexable is a key indexable memcached interface. It is a simple wrapper class of Cache::Memcached. Usually, we can't get any key information of stored data with using memcached. This module provides keys() method (likes CORE::keys()) for getting all of stored key information.

In fact, this module uses only a few patterns of knowable key, and it stores the key with the value of large hash-ref. It controls the large hash-ref when you call set, get or delete methods.

It was implantated some functions of Cache::Memcached. But the implanted functions are only documented functions. Note that some undocumented functions weren't implanted to this module.

CONSTRUCTOR

new

Takes one parameter, a hashref of options. Almost same as Cache::Memcached's constructor. But it has some additional parameter.

• logic

  The parameter of logic is the name of your chosen logic class or the entity of the logic class instance.

   $memd = Cache::Memcached::Indexable->new({
       logic      => 'Cache::Memcached::Indexable::Logic::DigestSHA1',
       logic_args => { set_max_power => 0xFF },
       %memcached_args,
   })

  and the following code is same as above:

   use Cache::Memcached::Indexable::Logic::DigestSHA1;
  
   $logic = Cache::Memcached::Indexable::Logic::DigestSHA1->new({
       set_max_power => 0xFF,
   });
   
   $memd = Cache::Memcached::Indexable->new({
       logic => $logic,
       %memcached_args,
   });

• logic_args

  The arguments of your specified logic class (see above.)

• memd

  You may specify your favorite memcached interface class. But it must have Cache::Memcached compatibility (e.g. Cache::Memcached::XS).
