I've been developing such a "money" module myself but I was nowhere close to the joda-money solution when I found out about it. Thanks and congrats for this very nice library.
Now, what would be nice to see in the library (in my opinion) is a more elaborate way to convert money instances between different currency units.
I think I could provide an initial version of such a utility class. I think it would supplement the money functionality that the library already provides.
The thing I propose is an object having the following functionality - I present it here as an interface, I have it implemented as a class.
class ExchangeRate {
// Converts the given money to the monetary amount in this rates other currency.
Money exchange(Money toExchange);
// Combines to exchange rates together that have a common currency units
ExchangeRate combine(ExchangeRate other);
}
An instance of exchange rate is something that represents the following "equasion": 1 unit of target currency = n units of source currency.
An example would be:
1 EUR = 1.3 USD
A user can pass either an amount in EUR or USD to get an equivalent Money instance in the other currency.
The combine operation would allow the user to get a cross exchange rate. If one has the following exchange rates:
1 EUR = 1.3 USD
1 GBP = 1.55 USD
than a combination of the first and second would result in the following rate:
1 EUR = 0.838710 GBP.
The convertedTo method on Money object could internally construct an instance of ExchangeRate and use the conversion logic.
I don't have the fancy ;-) from String parsing methods nor any special formatters for it but I think it would be a good start.
Tell me what you think about it.
