awk '
        !/^#/ {
                A[++c] = $0

                for ( i = 1; i <= c; i++ )
                {
                        print A[i]
                }

NAME
Jifty::DBI::Record::Cachable - records with caching behavior SYNOPSIS
package Myrecord; use base qw/Jifty::DBI::Record::Cachable/; DESCRIPTION
This module subclasses the main Jifty::DBI::Record package to add a caching layer. The public interface remains the same, except that records which have been loaded in the last few seconds may be reused by subsequent fetch or load methods without retrieving them from the database. METHODS
flush_cache This class method flushes the _global_ Jifty::DBI::Record::Cachable cache. All caches are immediately expired. _flush_key_cache Blow away this record type's key cache load_from_hash Overrides the implementation from Jifty::DBI::Record to add caching. load_by_cols Overrides the implementation from Jifty::DBI::Record to add caching. _cache_config You can override this method to change the duration of the caching from the default of 5 seconds. For example, to cache records for up to 30 seconds, add the following method to your class: sub _cache_config { { 'cache_for_sec' => 30 } } AUTHOR
