Class RowMutations

java.lang.Object

org.apache.hadoop.hbase.client.RowMutations

All Implemented Interfaces:

Comparable<Row>, Row

@InterfaceAudience.Public
 @InterfaceStability.Evolving
public class RowMutations
extends Object
implements Row

Performs multiple mutations atomically on a single row. Currently Put and Delete are supported. The mutations are performed in the order in which they were added.

We compare and equate mutations based off their row so be careful putting RowMutations into Sets or using them as keys in Maps.
