public class ItemImpl

extends ConfigurableEntityImpl

This represents a product or service that has a value. It is identified by a combination of the supplier, part number and, a version. Examples of a supplier are the manufacturer of a product, the publisher of a book, or the offerer of a course. This entity gets its price from the ItemPricingPolicy. Also, Items have a set of qualities, used to search and find items based on weighted qualities.
