Interface Currency<T extends CurrencyItem>

All Superinterfaces:

Catalog<T>, CatalogItem, java.lang.Comparable<java.lang.Object>, DataBasketEntryDestination, DataBasketEntrySource, DatasourceChangeListener, ExternalModificationListener, java.lang.Iterable<T>, Nameable, SpAggregate, SpItem

All Known Implementing Classes:

AbstractCurrency, CurrencyFilter, CurrencyImpl, EUROCurrencyImpl

public interface Currency<T extends CurrencyItem>
extends Catalog<T>

A special Catalog that represents a currency.

Currencies contain CurrencyItems and work together with MoneyBags. They are capable of parsing user input that is formatted according to the currency format for the specific currency they represent. It is recommended that you use a Locale specific algorithm for implementation, but this cannot be enforced.
