Member Function Documentation

void add const ExchangeRate ,
const Date startDate = Date::minDate(),
const Date endDate = Date::maxDate()
 

Add an exchange rate.

The given rate is valid between the given dates.

Note:
If two rates are given between the same currencies and with overlapping date ranges, the latest one added takes precedence during lookup.

ExchangeRate lookup const Currency source,
const Currency target,
Date  date = Date(),
ExchangeRate::Type  type = ExchangeRate::Derived
const
 

Lookup the exchange rate between two currencies at a given date. If the given type is Direct, only direct exchange rates will be returned if available; if Derived, direct rates are still preferred but derived rates are allowed.

Warning:
if two or more exchange-rate chains are possible which allow to specify a requested rate, it is unspecified which one is returned.
