<p>CHI::Driver::RawMemory - In-process memory cache that stores direct references</p>
<h1><a class='u' href='#___top' title='click to go to top of document'

>SYNOPSIS</a></h1>
<pre> use CHI;
my $hash = {};
my $cache = CHI->new( driver => 'RawMemory', datastore => $hash );
my $cache = CHI->new( driver => 'RawMemory', global => 1 );</pre>
<h1><a class='u' href='#___top' title='click to go to top of document'
name="DESCRIPTION"
>DESCRIPTION</a></h1>
<p>This is a subclass of <a href="http://search.cpan.org/perldoc?CHI%3A%3ADriver%3A%3AMemory" class="podlinkpod"
>CHI::Driver::Memory</a> that stores references to data structures directly instead of serializing / deserializing. This makes the cache faster at getting and setting complex data structures, but unlike most drivers, modifications to the original data structure <i>will</i> affect the data structure stored in the cache, and vica versa. e.g.</p>
<pre> my $cache = CHI->new( driver => 'Memory', global => 1 );
my $lst = ['foo'];
$cache->set('key' => $lst); # serializes $lst before storing
$cache->get('key'); # returns ['foo']
$lst->[0] = 'bar';
$cache->get('key'); # returns ['foo']
my $cache = CHI->new( driver => 'RawMemory', global => 1 );
my $lst = ['foo'];
$cache->set('key' => $lst); # stores $lst directly
$cache->get('key'); # returns ['foo']
$lst->[0] = 'bar';
$cache->get('key'); # returns ['bar']!</pre>

>SIZE AWARENESS</a></h1>
<p>For the purpose of <a href="http://search.cpan.org/perldoc?CHI#SIZE_AWARENESS" class="podlinkpod"
>size-awareness</a>, all items count as size 1 for this driver. (Because data structures are not serialized, there's no good way to determine their size.)</p>
<pre> # Keep a maximum of 10 items in cache
#
my $cache = CHI->new( driver => 'RawMemory', datastore => {}, max_size => 10 );</pre>
