Interface PersistenceObserver

All Known Implementing Classes:

PersistenceObserverAdapter

public interface PersistenceObserver

A PersistenceObserver is used to monitor the loading and saving of persistence palo objects like Subsets and CubeViews. Currently the API tries to load or save a persistence palo object completely and calls one of the defined callback methods afterwards.
