Examples of org.apache.hadoop.hbase.io.Cell

org.apache.hadoop.hbase.io.Cell
Cell - Used to transport a cell value (byte[]) and the timestamp it was stored with together as a result for get and getRow methods. This promotes the timestamp of a cell to a first-class value, making it easy to take note of temporal data. Cell is used all the way from HStore up to HTable.
