Overview

Rose::DB::Cache::Entry provides both an API and a default implementation of a cache entry for use with Rose::DB::Cache objects. A Rose::DB::Cache-derived class uses Rose::DB::Cache::Entry-derived objects to store cache entries.

The default implementation includes attributes for storing the cache key, the cached Rose::DB-derived object itself, and some boolean flags. Subclasses can add new attributes as desired.

Constructors

new PARAMS

Constructs a new Rose::DB::Cache::Entry object based on PARAMS, where PARAMS are name/value pairs. Any object method is a valid parameter name.

key [KEY]
