public class PreferenceScope
extends oracle.adfmf.framework.Scope

Embedded Java side for preferences.

The preferences with the following scopes will be persisted and have EL expressions created for them:
application
feature
oracle
internal
dynamic

The preferences with the following scope will be not persisted but will have EL expressions created for them:
volatile

Developers that want to add preferences to the system at runtime are encouraged to use the dynamic scope.

Method Detail

getInstance

public static final PreferenceScope getInstance()

refreshPreferences

public static void refreshPreferences()

Fetch all the application's preferences and update the PreferenceScope with any new values. Doing this will fire DCEs for all changed preference values.

populatePreferencesMap

public void populatePreferencesMap(java.util.HashMap preferences)

populate a subset of the preferences map starting at the top

Parameters:

preferences - - flat list of preferences (name-value pairs)

synchronizePreferencesMap

public void synchronizePreferencesMap(java.util.HashMap preferences)

Populate the preferences with the specified values. Any changes should fire appropriate data change events but these changes should not be sent back to the native side as they are assummed to have already been changed there.

Parameters:

preferences - the preferences to set
