Interface ExtObjectSet

All Superinterfaces:
ObjectSet

public interface ExtObjectSet
extends ObjectSet

extended functionality for the ObjectSet interface.

Every db4o ObjectSet always is an ExtObjectSet so a cast is possible.

The ObjectSet functionality is split to two interfaces to allow newcomers to focus on the essential methods.
