Class RowCell

java.lang.Object

com.google.cloud.bigtable.hbase.adapters.read.RowCell

All Implemented Interfaces:

Cell

public class RowCell
extends Object
implements Cell

This implementation of Cell is more efficient for Bigtable scanning than KeyValue . RowCell is pretty straight forward. Each *Array() method returns the array passed in in the constructor. Each *Offset() method returns 0. Each *Length() returns the length of the array. This implementation is a few microseconds quicker thank KeyValue, which makes a big performance difference for large scans.
