public class OrderPricingEngineImpl
extends PricingEngineService
implements OrderPricingEngine

An OrderPricingEngine implementation which computes the price for an order. It accomplishes this task by invoking a series of OrderPricingCalculators which incrementally compute the order's price:

• The first step is to allow the preCalculators to manipulate the price. They are invoked in the order in which they appear in the preCalculators list.
• The second step is to extract the calculators from any input PricingModels, and invoke them in the order in which they appear in the pPricingModels list. It's also at this stage that promotions are filtered based on stacking rules. Stacking rule logic will only be invoked if the pExtraParameters parameter is not null (in order for stacking rule tracking information to be added and used by other pricing engines).
• The last step is to invoke the postCalculators in the order in which they appear in the postCalculators list.

Note: if a particular order of calculator invocation is desired, sorting must be done prior to passing discounts/precalculators/postcalculators in to the Engine. Properties:

• licenseFileName is the name of the nucleus component which is the DCS license.
• preCalculators is a list of ItemPricingCalculators whose pricing methods should be invoked on the input pPriceQuote before any pricing models are evaluated.
• postCalculators is a list of ItemPricingCalculators whose pricing methods should be invoked on the input pPriceQuote after any pricing models are evaluated.
