Class MoneyBag

java.lang.Object
  money.MoneyBag

All Implemented Interfaces:

IMoney

public class MoneyBag

extends Object

implements IMoney

A MoneyBag defers exchange rate conversions. For example adding 12 Swiss Francs to 14 US Dollars is represented as a bag containing the two Monies 12 CHF and 14 USD. Adding another 10 Swiss francs gives a bag with 22 CHF and 14 USD. Due to the deferred exchange rate conversion we can later value a MoneyBag with different exchange rates. A MoneyBag is represented as a list of Monies and provides different constructors to create a MoneyBag.
