Class IntervalValuer

java.lang.Object
  uk.ac.liv.auction.agent.FixedValuer
      uk.ac.liv.auction.agent.IntervalValuer

All Implemented Interfaces:

AuctionEventListener, Parameterizable, Resetable, java.io.Serializable, ValuationPolicy

Direct Known Subclasses:

BuyerIntervalValuer, SellerIntervalValuer

public abstract class IntervalValuer

extends FixedValuer

Agents configured with this valuation policy will receive a unique private value from a common set of values starting at minValue and incrementing by step as each agent is assigned a valuation at agent setup time. This is useful for quickly specifying supply or demand curves with a constant "slope" (step).
