public class ItemPricingEngineImpl
extends PricingEngineService
implements ItemPricingEngine

An ItemPricingEngine implementation which computes the price for an order. It accomplishes this task by invoking a series of ItemPricingCalculators which incrementally compute the items' prices:

• 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.
• 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:

• licenseFileNames is the names of the nucleus components which are the B2B and B2C licenses.
• 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.
