java.lang.Objectorg.apache.hadoop.hbase.io.BatchOperation
public class BatchOperation
Batch update operation. If value is null, its a DELETE operation. If its non-null, its a PUT. This object is purposely bare-bones because many instances are created during bulk uploads. We have one class for DELETEs and PUTs rather than a class per type because it makes the serialization easier.
