All Implemented Interfaces:
InterfaceChecker<AbstractChecker<Currency,CheckerCurrency>,Currency>
public class CheckerCurrency extends AbstractChecker<Currency,CheckerCurrency>
A specialized checker for Currency instances, providing a fluent API to assert various currency properties such as symbol, fraction digits, and locale association.

Typical usage: 


 Currency usd = Currency.getInstance("USD");

 CheckerCurrency.check(usd)
     .hasSymbol("$")
     .withDefaultFractionDigits(2)
     .isFrom(Locale.US);

This class supports chaining multiple assertions in a fluent style and integrates with AbstractChecker for generalized validation handling.
