Storing object in spark streaming

[Something Something]

In my custom receiver for Spark Streaming I've code such as this:

                messages.toArray().foreach(msg => {
                  val m = msg.asInstanceOf[Message]
*                  store(m.getBody)*
                })

Instead of 'body' which is of type 'String', I would rather pass the entire
Message object, but when I say store(m), I get a compiler error saying:
"Cannot resolve reference store with such signature"

But I see this method in 'Receiver.scala':

  def store(dataItem: T) {
    executor.pushSingle(dataItem)
  }


How do I store the entire object? Please help. Thanks.
