.\" way too many mistakes in technical documents.

.SH "NAME"
Jifty::DBI::Record::Cachable \- records with caching behavior
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 2
\&  package Myrecord;
\&  use base qw/Jifty::DBI::Record::Cachable/;
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module subclasses the main Jifty::DBI::Record package to add a
caching layer.
.PP
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.
.SH "METHODS"
.IX Header "METHODS"
.SS "flush_cache"
.IX Subsection "flush_cache"
This class method flushes the _global_ Jifty::DBI::Record::Cachable 
cache.  All caches are immediately expired.
.SS "_flush_key_cache"
.IX Subsection "_flush_key_cache"
Blow away this record type's key cache
.SS "load_from_hash"
.IX Subsection "load_from_hash"
Overrides the implementation from Jifty::DBI::Record to add caching.
.SS "load_by_cols"
.IX Subsection "load_by_cols"
Overrides the implementation from Jifty::DBI::Record to add caching.
.SS "_cache_config"
.IX Subsection "_cache_config"
You can override this method to change the duration of the caching
from the default of 5 seconds.
.PP
For example, to cache records for up to 30 seconds, add the following
method to your class:
.PP
.Vb 3
\&  sub _cache_config {
\&      { \*(Aqcache_for_sec\*(Aq => 30 }
\&  }
