NAME Cache::Sliding - Cache using sliding time-based expiration strategy VERSION This document describes Cache::Sliding version v2.0.0 SYNOPSIS use Cache::Sliding; $cache = Cache::Sliding->new(10*60); $cache->set($key, $value); $value = $cache->get($key); $cache->del($key); DESCRIPTION Implement caching object using sliding time-based expiration strategy (data in the cache is invalidated by specifying the amount of time the item is allowed to be idle in the cache after last access time). Use EV::timer, so this module only useful in EV-based applications, because cache expiration will work only while you inside EV::loop. INTERFACE new $cache = Cache::Sliding->new( $expire_after ); Create and return new cache object. Elements in this cache will expire between $expire_after seconds and 2*$expire_after seconds. set $cache->set( $key, $value ); Add new item into cache. Will replace existing item for that $key, if any. get $value = $cache->get( $key ); Return value of cached item for $key. If there no cached item for that $key return nothing. For example, if you may keep undefined values in cache and still wanna be able to check is item was found in cache: $cache->set( 'item 1', undef ); $val = $cache->get( 'item 1' ); # $val is undef @val = $cache->get( 'item 1' ); # @val is (undef) $val = $cache->get( 'nosuch' ); # $val is undef @val = $cache->get( 'nosuch' ); # @val is () del $cache->del( $key ); Remove item for $key from cache, if any. Return nothing. SUPPORT Bugs / Feature Requests Please report any bugs or feature requests through the issue tracker at https://github.com/powerman/perl-Cache-Sliding/issues.
