NAME

       CHI::Driver::RawMemory - In-process memory cache that stores direct references

VERSION

       version 0.54

SYNOPSIS

	   use CHI;

	   my $hash = {};
	   my $cache = CHI->new( driver => 'RawMemory', datastore => $hash );

	   my $cache = CHI->new( driver => 'RawMemory', global => 1 );

DESCRIPTION

       This is a subclass of CHI::Driver::Memory 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 will affect the data structure stored in the cache, and vica versa. e.g.

	   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']!

CONSTRUCTOR OPTIONS

       Same as CHI::Driver::Memory.

SIZE AWARENESS

       For the purpose of size-awareness, all items count as size 1 for this driver. (Because data structures are not serialized, there's no good
       way to determine their size.)

	   # Keep a maximum of 10 items in cache
	   #
	   my $cache = CHI->new( driver => 'RawMemory', datastore => {}, max_size => 10 );

ACKNOWLEDGEMENTS

       Thanks to Yuval Kogman whose Cache::Ref inspired me to do this.
