public abstract class StrategyEvaluator

extends java.lang.Object

This class defines a negotation strategy, i.e. how the bidding strategy changes with time and or bids received. Following initialisation, negotiation proceeds via, first a call to the evaluateFirst methods, the followed by zero or more calls to the evaluateNext method. These two call return the following message types:

OK	the negotiation has terminated successfully
FAIL	the negotaition failed
WAIT	wait until some timeout period
MESSAGE	a message needs to be sent
