All Implemented Interfaces:

public class EORemoteStorageDefaults
extends EODefaults

EORemoteStorageDefaults works together with the server side of a Java Client application to manage the defaults of an application: When the client starts up, it tries to receive values from the distribution context on the server side, and when the application terminates, it asks the distribution context to store all the persistent values. The distribution context in turn sends out notifications to read or write the default values, so you can register for these notifications on the server side and implement your own storage mechanism (for example to store the user defaults in the database).
