org.apache.hadoop.hbase.client.Result.list()
Return an cells of a Result as an array of KeyValues WARNING do not use, expensive. This does an arraycopy of the cell[]'s value. Added to ease transition from 0.94 -> 0.96. @deprecated as of 0.96, use {@link #listCells()} @return all sorted List of KeyValues; can be null if no cells in the result
