Class DeleteValue

java.lang.Object

com.basho.riak.client.api.RiakCommand<Void,Location>

com.basho.riak.client.api.commands.kv.DeleteValue

public final class DeleteValue
extends RiakCommand<Void,Location>

Command used to delete a value from Riak.

Deleting an object from Riak is a simple matter of supplying a Location and executing the operation.

Note that this operation returns a Void type upon success. Any failure will be thrown as an exception when calling DeleteValue synchronously or when calling the future's get methods.

 Namespace ns = new Namespace("my_type", "my_bucket");
 Location loc = new Location(ns, "my_key");
 DeleteValue dv = new DeleteValue.Builder(loc).build();
 client.execute(dv);

All operations can called async as well.

 ...
 RiakFuture<Void, Location> future = client.executeAsync(dv);
 ...
 future.await();
 if (future.isSuccess())
 { 
     ... 
 }
