jmri.util.prefs
This package provides two mechanisms for storing preferences and one mechanism for storing user interface state within a JMRI profile: JmriConfigurationProvider Complex preferences within an XML element provided by the object storing and retrieving the element. JmriPreferencesProvider Simple preferences within a Preferences construct. JmriUserInterfaceConfigurationProvider Complex user interface state within an XML element provided by the object storing and retrieving the element. These three classes provide arbitrary read/write access to the underlying storage, such that writing a users preferences does not require any part of a JMRI application have knowledge of every object that manages users preferences.
