Package oracle.adf.share.prefs Description

This package allows applications to store and retrieve user and system levels of preference data. This data is persistented in the MDS repository in which the metadata associated with the ADF application using these Preference classes resides. By default there are two predefined levels of preference nodes, one for user preferences based on the J2EE authenticated user and one for system preferences. However, developers can make use of the helper methods which enable access to Preferences based on a leveled priority, namely provide user preferences over system preferences where the preference item exists in the user preference node as well as the system preference node. Should the preference only exist in the system preference node then the value associated with the system preference will be returned instead.
NOTE: In order to support usage of the ADFPreferences Utility outside of the context of an ADF Web Application it is necessary to use the ADFPreferencesFactory(ADFPreferencesConfig config) constructor, where the ADFPreferencesConfig is based on the ADFPreferencesSimpleConfig(MDSInstance) object, that takes an MDSInstance object in it's constructor.
Consumers of the Preference Utility working within the context of an ADF Web Application should use the constructor which takes no arguments as this will obtain the MDS Instance from the ADF Context object that has been configured against the web application.
