Class BatchOperation

java.lang.Object
  org.apache.hadoop.hbase.io.BatchOperation

All Implemented Interfaces:

HeapSize, org.apache.hadoop.io.Writable

Deprecated. As of hbase 0.20.0, replaced by new Get/Put/Delete/Result-based API.

public class BatchOperation
extends Object
implements org.apache.hadoop.io.Writable, HeapSize

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.
