Classes | Description

This package provides a preferences mechanism, that is, a means of writing configuration data (key/value pairs) to a persistent data store and retrieving it from there. There are two different kinds of stores available: one for storing user data and one for storing system configuration data. Since the underlying implementation is dependent on the operating system, this package is designed to allow the installation of a custom service provider implementation.
