Class CellModel

java.lang.Object

org.apache.hadoop.hbase.rest.model.CellModel

All Implemented Interfaces:

Serializable, ProtobufMessageHandler

@InterfaceAudience.Private
public class CellModel
extends Object
implements ProtobufMessageHandler, Serializable

Representation of a cell. A cell is a single value associated a column and optional qualifier, and either the timestamp when it was stored or the user- provided timestamp if one was explicitly supplied.
