| com.db4o.ext.ExtObjectServer
All known Subclasses: com.db4o.internal.cs.ObjectServerImpl,
| ExtObjectServer | | public interface ExtObjectServer extends ObjectServer(Code) | | extended functionality for the ObjectServer interface.
Every ObjectServer also always is an ExtObjectServer
so a cast is possible.
com.db4o.ObjectServer.ext is a convenient method to perform the cast.
The functionality is split to two interfaces to allow newcomers to
focus on the essential methods.
