                               java.lang.String table,

Method Detail

close

public void close()

Description copied from interface: BatchScanner

Cleans up and finalizes the scanner

Specified by:

close in interface BatchScanner

setRanges

public void setRanges(java.util.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 java.util.Iterator<java.util.Map.Entry<Key,Value>> iterator()

Description copied from interface: BatchScanner

Returns an iterator over a 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 java.lang.Iterable<java.util.Map.Entry<Key,Value>>

Specified by:

iterator in interface BatchScanner
