      • close

        public void close()
        Description copied from interface: ScannerBase

      • setRanges

        public void setRanges​(Collection<Range> ranges)
        Description copied from interface: BatchScanner

      • iterator

        public Iterator<Map.Entry<Key,​Value>> iterator()
        Description copied from interface: ScannerBase
        Returns an iterator over an accumulo table. This iterator uses the options that are currently set for its lifetime, so setting options will have no effect on existing iterators.

        Keys returned by the iterator are not guaranteed to be in sorted order.

        Specified by:
