NAME
Cache::LRU - a simple, fast implementation of LRU cache in pure perl
SYNOPSIS
use Cache::LRU;
my $cache = Cache::LRU->new(
size => $max_num_of_entries,
);
$cache->set($key => $value);
$value = $cache->get($key);
$removed_value = $cache->remove($key);
DESCRIPTION
Cache::LRU is a simple, fast implementation of an in-memory LRU cache in
pure perl.
FUNCTIONS
Cache::LRU->new(size => $max_num_of_entries)
Creates a new cache object. Takes a hash as the only argument. The only
parameter currently recognized is the "size" parameter that specifies
the maximum number of entries to be stored within the cache object.
$cache->get($key)
Returns the cached object if exists, or undef otherwise.
$cache->set($key => $value)
Stores the given key-value pair.
$cache->remove($key)
Removes data associated to the given key and returns the old value, if
any.
$cache->clear($key)
Removes all entries from the cache.
