Class FilePreferencesFactory

java.lang.Object

org.rhq.core.util.preferences.FilePreferencesFactory

All Implemented Interfaces:

PreferencesFactory

public class FilePreferencesFactory
extends Object
implements PreferencesFactory

PreferencesFactory implementation that stores the preferences in a single user-defined file. To use it, set the system property -Djava.util.prefs.PreferencesFactory=org.rhq.core.util.preferences.FilePreferencesFactory.

The file defaults to ${user.home}/.fileprefs, but may be overridden with the system property rhq.preferences.file

Both the system root and user root default to the user.home system property by default.

NOTE: This implementation does not allow a '/' character in the preference property names (although it's fine in the values).
