atg.commerce.pricing.ShippingPricingEngine is an extension of the PricingEngine interface. It describes an object that determines prices for ShippingGroup objects.

Implementations of this interface determine the cost of shipping the contents of a shipping group. The priceShippingGroup method asks this object to determine a price for the specified shipping group. The getAvailableMethods call returns the methods available for shipping the specified group.

Oracle ATG Web Commerce provides the ShippingPricingEngineImpl class as a default implementation of the ShippingPricingEngine interface. It computes the shipping cost for an order by invoking a series of ShippingPricingCalculators.
