Method Detail

setRanges

public void setRanges(Collection<Range> ranges)

Description copied from interface: BatchScanner

Allows scanning over multiple ranges efficiently.

Specified by:

setRanges in interface BatchScanner

Parameters:

ranges - specifies the non-overlapping ranges to query

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:

iterator in interface Iterable<Map.Entry<Key,Value>>

Specified by:

iterator in interface ScannerBase

Overrides:

iterator in class MockScannerBase

Returns:

an iterator over Key,Value pairs which meet the restrictions set on the scanner

close

public void close()

Description copied from interface: ScannerBase

Closes any underlying connections on the scanner

Specified by:

close in interface BatchScanner

Specified by:

close in interface ScannerBase

Overrides:

close in class org.apache.accumulo.core.client.impl.ScannerOptions
