Examples of org.apache.derby.iapi.store.access.ScanController.fetchLocation()

org.apache.derby.iapi.store.access.ScanController.fetchLocation()
Fetch the location of the current position in the scan. The destination location is replaced with the location corresponding to the current position in the scan. The destination location must be of the correct actual type to accept a location from the underlying conglomerate location. The results of a fetchLocation() performed on a scan after next() has returned false are undefined. The results of a fetchLocation() performed on a scan positioned on a deleted row are undefined, note that this can happen even if next() has returned true (for instance the client can delete the row, or if using read uncommitted another thread can delete the row after the next() call but before the fetchLocation). @exception StandardException Standard exception policy.
