@Node
public class EventRecorder
extends User

Records all events in the world, saves them to the database, plays them back. This is a special case of Client that has no session, but copies scene and properties from the client it impersonates. By overriding Client's sendMessage(), it maintains internal list of received events. Once recording is done, i.e. stop() is called, event list is persisted to the database.
