Tie::Collection - A trivial implementaion of Tie::Cache by using a tied handle of a hash for storage.
use Tie::Collection; use DB_File; use Fcntl;

Tie::Collection implements a trivial implementation of Tie::Cache by Joshua Chamas, that gets a tied hash handle to store the data. Assumption was that most common use will be disk storage, therfore the storage hash will probably be tied.
Tie::Collection is useful with DB_File or MLDBM, as will as with Tie::DBI. It was designed to be used with HTML::HTPL in order to cache objects accesses via a key, so they don't have to be read from disk again and again.
Tie::Collection needs two parameters: The handled of the tied hash, and a hashref with parameters to pass to Tie::Cache. (See manpage).
