Class BrokerAuthentication

java.lang.Object
  org.powertac.common.msg.BrokerAuthentication

public class BrokerAuthentication
extends Object

This message is used for authenticating a broker with the server. Broker sends this message to the server with its username, password, and the name of the queue through which it wishes to receive messages. The password is ignored by a standalone server; in a tournament situation it is the game-token received from the tournament manager. The queue name may be the username, but in a tournament situation using some sort of difficult-to-guess hash (or possibly the game token) will make it more difficult (but not impossible) for other brokers to intercept its messages. If the login is accepted, a BrokerAccept message is returned.
