      def help
        return <<-EOF
Delete all cells in a given row; pass a table name, row, and optionally
a column and timestamp. Examples:

  hbase> deleteall 'ns1:t1', 'r1'
  hbase> deleteall 't1', 'r1'
  hbase> deleteall 't1', 'r1', 'c1'
  hbase> deleteall 't1', 'r1', 'c1', ts1
  hbase> deleteall 't1', 'r1', 'c1', ts1, {VISIBILITY=>'PRIVATE|SECRET'}

The same commands also can be run on a table reference. Suppose you had a reference
t to table 't1', the corresponding command would be:

  hbase> t.deleteall 'r1'
  hbase> t.deleteall 'r1', 'c1'
  hbase> t.deleteall 'r1', 'c1', ts1
  hbase> t.deleteall 'r1', 'c1', ts1, {VISIBILITY=>'PRIVATE|SECRET'}
EOF
      end

      def command(table, row, column = nil,
                  timestamp = org.apache.hadoop.hbase.HConstants::LATEST_TIMESTAMP, args = {})
        deleteall(table(table), row, column, timestamp, args)
      end

      def deleteall(table, row, column = nil,
                    timestamp = org.apache.hadoop.hbase.HConstants::LATEST_TIMESTAMP, args = {})
        format_simple_command do
          table._deleteall_internal(row, column, timestamp, args)
        end
      end
    end
  end
end
