Class DefaultEJBDataAccessClient

java.lang.Object

org.plasma.sdo.access.client.DefaultEJBDataAccessClient

All Implemented Interfaces:

DataAccessClient

public class DefaultEJBDataAccessClient
extends Object
implements DataAccessClient

Hides the complexity of collecting only the objects that need to be committed and sent to the app layer. We don't want to send ANY objects or properties we don't have to. Serialization is expensive!
