NAME

Data::Downloader::Cache

SYNOPSIS

    my $cache = Data::Downloader::Cache::LRU->new(repository => <repository>);
    $cache->purge if $cache->needs_purge;

DESCRIPTION

This is the base class for caching algorithms.

A Data::Downloader::Cache acts on a repository; a repository uses a particular cache algorithm. The cache algorithm is then responsible for determining which files have expired, and purging them as necessary.

METHODS

repository

Get or set the repository (a DD::Repository object)

purge

Purge all expired files for a repository.

needs_purge

Does the cache for this repository need to be purged?

find_expired_files

Find all the files which are expired, and may be purged.

Returns a list of DD::File objects.
