示例1: scanBackward

        public IEnumerable<KeyValuePair<RecordKey, RecordData>> scanBackward(IScanner<RecordKey> scanner)
        {
            var new_scanner = new ScanRange<RecordKey>(
               new RecordKeyComparator().appendKeyPart(this.subset_name).appendKeyPart(scanner.genLowestKeyTest()),
               new RecordKeyComparator().appendKeyPart(this.subset_name).appendKeyPart(scanner.genHighestKeyTest()), null);

            foreach (var rec in next_stage.scanBackward(new_scanner)) {
                if (this.subset_name.CompareTo(rec.Key.key_parts[0]) != 0) {
                    // Console.WriteLine("SubsetStage.scanBackward: no more records");
                    yield break;
                }
                RecordKeyType_RecordKey orig_key = (RecordKeyType_RecordKey)rec.Key.key_parts[1];

                yield return new KeyValuePair<RecordKey, RecordData>(orig_key.GetRecordKey(), rec.Value);
            }

示例2: scanBackward

        public IEnumerable<KeyValuePair<RecordKey, RecordUpdate>> scanBackward(IScanner<RecordKey> scanner)
        {
            IComparable<RecordKey> lowkeytest = scanner.genLowestKeyTest();
            IComparable<RecordKey> highkeytest = scanner.genHighestKeyTest();

            RecordLocator rloc = _findRecord(highkeytest, true).before_keytest;

            while (rloc.have_record &&   // while we have a new record to test
                (lowkeytest.CompareTo(rloc.record.Key) < 0))  // and it's above the lowkey
            {
                if (scanner.MatchTo(rloc.record.Key)) {
                    yield return rloc.record;
                }
                _prevRecord(ref rloc);
