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.
