Method Details

delete

void delete()
     throws MutationsRejectedException,
TableNotFoundException

Deletes the ranges specified by setRanges(java.util.Collection<org.apache.accumulo.core.data.Range>).

Throws:

MutationsRejectedException - this can be thrown when deletion mutations fail

TableNotFoundException - when the table does not exist

setRanges

void setRanges(Collection<Range> ranges)

Allows deleting multiple ranges efficiently.

Parameters:

ranges - specifies the non-overlapping ranges to query

close

void close()

Description copied from interface: ScannerBase

Closes any underlying connections on the scanner. This may invalidate any iterators derived from the Scanner, causing them to throw exceptions.

Specified by:

close in interface AutoCloseable
