Interface CatalogItem

All Known Subinterfaces:

Catalog, Currency, CurrencyItem, ListenableCatalog

All Known Implementing Classes:

CatalogItemImpl

public interface CatalogItem

extends Nameable, Comparable

An item in a Catalog.

CatalogItems describe available objects by their attributes. The only attribute that is mandatory is a key (String), usually a name, but it could be an ID-Number or anything. A CatalogItem can have a value attribute.

Note that the name as obtained via Nameable.getName() is used as the CatalogItem's key when inserting the CatalogItem inside a Catalog.

CatalogItems are contained in Catalogs.
