Oracle ATG Web Commerce - OrderDiscountCalculator

OrderDiscountCalculator

The atg.commerce.pricing.OrderDiscountCalculator class implements the OrderPricingCalculator. It calculates OrderPriceInfo values for orders when the calculator is invoked. This calculator receives a MatchingObject and DiscountStructure from the pricing engine, then computes an OrderPriceInfo based on the input PricingModel (RepositoryItem). It takes non-discountable items into account when making this computation.

See the ATG Platform API Reference for detailed information on OrderDiscountCalculator and its related classes.

The OrderDiscountCalculator component is a preconfigured instance of the class atg.commerce.pricing.OrderDiscountCalculator. It is the default discount calculator for order promotions.
