Method Detail

flushDeletedObjects

public final void flushDeletedObjects()

Frees the resources in your OLAP API client application for any objects that were deleted from cached metadata because of a call to the update method. It is not necessary to call this method after you call update; however, resources for deleted objects are not freed until you call flushDeletedObjects or exit your program. If you are not concerned about resources, you do not need to call this method.
