Class CellModel

java.lang.Object

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

All Implemented Interfaces:

Serializable, ProtobufMessageHandler

@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.

 <complexType name="Cell">
   <sequence>
     <element name="value" maxOccurs="1" minOccurs="1">
       <simpleType>
         <restriction base="base64Binary"/>
       </simpleType>
     </element>
   </sequence>
   <attribute name="column" type="base64Binary" />
   <attribute name="timestamp" type="int" />
