Database.AnyDBM.StringDBM

Written by John Goerzen, [e-mail]

This AnyDBM implementation is very simple. It can store data on-disk in a persistent fashion, using a very simple String representation. While the file is open, an in-memory cache is maintained. The data is written out during a call to flush or close.
