      atg.nucleus.GenericService
          atg.commerce.pricing.ItemPriceCalculator

All Implemented Interfaces:

ItemPriceSourceHandler, ItemPricingCalculator, atg.naming.AbsoluteNameable, NameContextBindingListener, NameContextElement, atg.naming.NameContextParentable, NameResolver, AdminableService, atg.nucleus.Configured, ApplicationLogging, atg.nucleus.logging.ApplicationLoggingSender, atg.nucleus.logging.TraceApplicationLogging, VariableArgumentApplicationLogging, ComponentNameResolver, Service, ServiceListener, java.util.EventListener

Direct Known Subclasses:

ConfigurableItemPriceCalculator, ItemListPriceCalculator, ItemSalePriceCalculator

public abstract class ItemPriceCalculator
extends GenericService
implements ItemPricingCalculator, ItemPriceSourceHandler

Superclass for all CommerceItem calculators. Consolidates functionality that some item price calculators have in common. ItemPriceCalculator extends ApplicationLoggingImpl, so classes that extend this one have access to Nucleus logging services. This class contains a single abstract method: priceItem. Extending classes implement this method to leverage this class's other CommerceItem pricing methods.

Properties:

• loggingIdentifier is the ID that this class uses to identify itself in logs.
• pricePropertyName is the name of the property of the priceSource which represents an item's price.
• requirePriceValue: if true, an exception is thrown if the priceSource if the CommerceItem doesn't have its [pricePropertyName] property set.
• priceFromCatalogRef: if true, getPriceSource returns the catalogRef property of the input CommerceItem. If false, getPriceSource returns the productRef property.
• getPriceSource returns the catalogRef property of the input CommerceItem if priceFromCatalogRef is true. If priceFromCatalogRef is false, getPriceSource returns the productRef property.
