Rate Adjusters

Rate Adjuster is an optional feature that allows you to bulk modify all rates received by RateManager. Possible use cases include providing a discount for the received rate or, on the contrary, charging extra for handling. Rate adjusters should implement the IRateAdjuster interface and can be added by calling the RateManager.AddRateAdjuster function. If multiple adjusters are provided, they are called sequentially in the order of adding.

Sample Rate Adjuster:

    public class PercentageRateAdjuster : IRateAdjuster
    {
        private readonly decimal _amount;

        public PercentageRateAdjuster(decimal amount)
        {
            _amount = amount;
        }

        public Rate AdjustRate(Rate rate)
        {
            rate.TotalCharges = rate.TotalCharges * _amount;
            return rate;
        }
    }

Sample usage (provide 10% discount):

    var rateManager = new RateManager();
    rateManager.AddRateAdjuster(new PercentageRateAdjuster(.9M));
