AbstractCurrencyDateCalculator (Date Calculator Common 1.4.8 API)

java.lang.Object
- net.objectlab.kit.datecalc.common.ccy.AbstractCurrencyDateCalculator<E>

All Implemented Interfaces:

CurrencyDateCalculator<E>, NonWorkingDayChecker<E>
```
public abstract class AbstractCurrencyDateCalculator<E extends Serializable>
extends Object
implements CurrencyDateCalculator<E>, NonWorkingDayChecker<E>
```
Abstract Currency calculator implementation in order to encapsulate all the common functionality between Jdk/Jdk8 and Joda implementations. It is parameterized on <E> but basically Date and LocalDate are the only viable values for it for now. This follows convention for currency, see http://www.londonfx.co.uk/valdates.html
Currency Holiday
For most T+2 currency pairs (spotLag=2), if T+1 is a USD holiday, then this does not normally affect the spot date, but if a non-USD currency in the currency pair has a holiday on T+1, then it will make the spot date become T+3. If USD or either currency of a pair have a holiday on T+2, then the spot date will be T+3. This means, for example, that crosses such as EUR/GBP can never have a spot date on 4th July (although such a date could be quoted as an outright).
Latin American currencies
USD holidays normally affect the spot date only if T+2 is a USD holiday. If T+1 is a USD holiday, this does not normally prevent T+2 from being the spot date. Certain Latin American currencies (ARS, CLP and MXN) are an exception to this. If T+1 is a USD holiday, then the spot date for the affected currencies will be T+3. For example, if the trade date is a Monday and a USD holiday falls on the Tuesday, then the spot date for EUR/USD will be the Wednesday, but the spot date for USD/MXN will be the Thursday.
