In messagepack, error while getting value from Map

Question

I'm trying to serialize map using messagpack.write(map). During deserialization using messagepack.read(byte[]) i got MapValue. But I cannot fetch the values using MapValue.get(key). Look this problem below

  HashMap<Object,Object> map = new HashMap<Object, Object>();
  map.put(1,"ONE");
  map.put("ONE","TWO");
  MessagePack m= new MessagePack();
  byte[] b = m.write(map);
  MessagePack m1 = new MessagePack();
  MapValue value = (MapValue)m1.read(b);
  System.out.println(value);// here I am getting {1:"ONE",2:"TWO"}

 System.out.println( value.get(1)); // printing the value for key 1. I am getting null.

Please help on this.. Thanking you.

You need to use ValueFactory and convert key to use a Value interface. It's not really intuitive

// instead of value.get(1) use following
System.out.println(value.get(ValueFactory.createIntegerValue(1)));

// if the key would be a String use:
System.out.println(value.get(ValueFactory.createRawValue("key")));
