Interface RoundingProviderSpi

public interface RoundingProviderSpi

This SPI allows to extends/override the roundings available for CurrencyUnit. The JSRs implementation already provides default roundings. By registering instances of this interface using the Bootstrap, the default behaviour can be overridden and extended, e.g. for supporting also special roundings.

Implementations of this interface must be

• thread-safe
• not require loading of other resources.

If required, it is possible to implement this interface in a contextual way, e.g. providing different roundings depending on the current EE application context. Though in most cases rounding should be a general concept that does not require contextual handling.
