public class JispFilesystemStore
extends AbstractJispFilesystemStore
implements org.apache.avalon.framework.parameters.Parameterizable, org.apache.avalon.framework.activity.Disposable

This store is based on the Jisp library (http://www.coyotegulch.com/jisp/index.html). This store uses B-Tree indexes to access variable-length serialized data stored in files.
