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.
