extends Ice.OnewayCallback
Each collection can also be unloaded, independently
of the object itself. To unload all collections, use:
object.unloadCollections();
This is useful when it is possible that a collection no
longer represents the state in the database, and passing the
collections back to the server might delete some entities.
Sending back empty collections can also save a significant
amount of bandwidth, when working with large data graphs.
