org.apache.derby.iapi.store.access.conglomerate.ScanManager.closeForEndTransaction()

Close scan as part of terminating a transaction.

Use this call to close the scan resources as part of committing or aborting a transaction. The normal close() routine may do some cleanup that is either unnecessary, or not correct due to the unknown condition of the scan following a transaction ending error. Use this call when closing all scans as part of an abort of a transaction. @param closeHeldScan If true, means to close scan even if it has beenopened to be kept opened across commit. This is used to close these scans on abort. @return boolean indicating that the close has resulted in a real closeof the scan. A held scan will return false if called by closeForEndTransaction(false), otherwise it will return true. A non-held scan will always return true. @exception StandardException Standard exception policy.

            // loop from end to beginning, removing scans which are not held.
            for (int i = scanControllers.size() - 1; i >= 0; i--)
            {
                ScanManager sc = (ScanManager) scanControllers.get(i);


                if (sc.closeForEndTransaction(closeHeldControllers))
                {
                    // TODO - now counting on scan's removing themselves by 
                    // calling the closeMe() method.
                    /* scanControllers.removeElementAt(i); */
                }
