public class Auctioneer
extends BaseMatcherEndpoint
implements MatcherEndpoint

This class represents an Auctioneer component which will receive all Bid of other agents as a single Bid or as an aggregate Bid via one or more Concentrator.

It is responsible for defining and sending the MarketBasis and calculating the equilibrium based on the Bid from the different agents in the topology. This equilibrium is communicated to the agents down the hierarchy in the form of price update messages.
