All Implemented Interfaces:

CurrencyConverter

public final class PinnedExchangeRates
extends Object
implements CurrencyConverter

The rates pinned in a spec's commercial.exchangeRates: units of the spec currency per one unit of each keyed currency. They are part of the spec's fingerprint, so a pinned run is reproducible. They are applied as given: a converted range is widened only by the spec's own bandPercent (default 0).
