NAME

6       CHI::Driver::Memory - In-process memory based cache
7

VERSION

9       version 0.44
10

SYNOPSIS

12           use CHI;
13
14           my $hash = {};
15           my $cache = CHI->new( driver => 'Memory', datastore => $hash );
16
17           my $cache = CHI->new( driver => 'Memory', global => 1 );

DESCRIPTION

20       This cache driver stores data on a per-process basis.  This is the
21       fastest of the cache implementations, but data can not be shared
22       between processes.  Data will remain in the cache until cleared,
23       expired, or the process dies.
24
25       To maintain the same semantics as other caches, references to data
26       structures are deep-copied on set and get. Thus, modifications to the
27       original data structure will not affect the data structure stored in
28       the cache, and vica versa. See CHI::Driver::RawMemory for a faster
29       memory cache that sacrifices this behavior.

CONSTRUCTOR OPTIONS

32       When using this driver, the following options can be passed to
33       CHI->new() in addition to the CHI. One of datastore or global must be
34       specified, or else a warning (possibly an error eventually) will be
35       thrown.
36
37       datastore [HASH]
38           A hash to be used for storage. Within the hash, each namespace is
39           used as a key to a second-level hash.  This hash may be passed to
40           multiple CHI::Driver::Memory constructors.
41
42       global [BOOL]
43           Use a standard global datastore. Multiple caches created with this
44           flag will see the same data. Before 0.21, this was the default
45           behavior; now it must be specified explicitly (to avoid
46           accidentally sharing the same datastore in unrelated code).
47

DISCARD POLICY

49       For CHI/SIZE AWARENESS caches, this driver implements an 'LRU' policy,
50       which discards the least recently used items first. This is the default
51       policy.
