Member Function Documentation

add()

void add	(	const ExchangeRate &	rate,
		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.

Definition at line 45 of file exchangeratemanager.cpp.

Here is the call graph for this function:

Here is the caller graph for this function:

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.
