NAME

       CHI::Driver::Memory - In-process memory based cache

VERSION

       version 0.61

SYNOPSIS

           use CHI;

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

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

           my $cache = CHI->new( driver => 'Memory', global => 0 );

DESCRIPTION

       This cache driver stores data on a per-process basis.  This is the fastest of the cache implementations,
       but data can not be shared between processes.  Data will remain in the cache until cleared, expired, or
       the process dies.

       To maintain the same semantics as other caches, references to data structures are deep-copied on set and
       get. Thus, modifications to the original data structure will not affect the data structure stored in the
       cache, and vice versa. See CHI::Driver::RawMemory for a faster memory cache that sacrifices this
       behavior.

CONSTRUCTOR OPTIONS

       When using this driver, the following options can be passed to CHI->new() in addition to the CHI. One of
       datastore or global must be specified, or else a warning (possibly an error eventually) will be thrown.

       datastore [HASHREF]
           A  reference  to a hash to be used for storage. Within the hash, each namespace is used as a key to a
           second-level hash.  This hash may be passed to multiple CHI::Driver::Memory constructors.

       global [BOOL]
           Use a standard global datastore. Multiple caches created with this set to  true  will  see  the  same
           data.  Before  0.21,  this  was  the  default behavior; now it must be specified explicitly (to avoid
           accidentally sharing the same datastore in unrelated code).

           If this is set to false then datastore will be set to a new reference to a hash.

DISCARD POLICY

       For size aware caches, this driver implements an 'LRU' policy, which discards  the  least  recently  used
       items first. This is the default policy.
