finished

public abstract void finished(int totaloeCount)

CallBack from MOOManager.updateObjects

Parameters:

oeCount - The number count of the associated Objectentry(s) that have been processed. Processing does not mean successfully completed but an attempt was made. The updateObjects() call is now complete and will be returning. The returned count may be 0 if no OE's existed or were attempted to be processed. This is called as the last thing before returning from updateObjects() with the number of currently completed objects, whether any exceptions occurred or whether the update() or handleException() calls above returned ABORT_UPDATE
