/**
 * Represents a supplier of {@link CurrencyUnit}-valued results. This is the
 * {@link CurrencyUnit}-producing specialization of {@code Supplier} (as in Java 8).
 * 
 * 
 * There is no requirement that a distinct result be returned each time the
 * supplier is invoked.
 * 
 * 

 * This is a functional interface whose
 * functional method is {@link #getCurrency()}.
 * This class does not extends {@code java.util.function.Supplier} since {@link MonetaryAmount} implements
 * both supplier interfaces, {@link NumberSupplier} and {@link CurrencySupplier},
 * which will lead
 * to method name conflicts.
