public class SetAllCmd extends CmdBase implements Cmd<Boolean>
An Usage Example:
The following code will stores a key with a value and two subkeys in a k2hdkc cluster.
package com.example;
import ax.antpick.k2hdkc.*;
import com.sun.jna.*;
import com.sun.jna.ptr.*;
import java.io.IOException;
import java.util.*;
import java.util.stream.*;
public class App {
public static void main(String[] args) {
try (Cluster c = Cluster.of("cluster/slave.yaml");
Session s = Session.of(c); ) {
String[] subkeys = {"subkey1", "subkey2"};
SetAllCmd set = SetAllCmd.of("key", "val", subkeys);
assert (set.execute(s).get().isSuccess());
// 1. get key
GetCmd get = GetCmd.of("key");
String str = (String) get.execute(sess).get().getValue();
System.out.println(str);
// 2. get subkeys
GetSubkeysCmd getsub = GetSubkeysCmd.of("key");
List<String> list = (List<String>) get.execute(sess).get().getValue();
System.out.println(list.get(0)); // subkey1
System.out.println(list.get(1)); // subkey2
} catch (IOException ex) {
System.out.println(ex.getMessage());
assert (false);
}
}
}
You shoule see only the "key", "subkey1" and "subkey2" message on the stdout if you could successfully run it. Before running the code above, You should run three processes.
The following commands in this repository will run all processes you need in localhost.
$ cd cluster
$ sh start_server.sh
