cache()

void cache

(

bool

enable = true

)

if cache is enabled, the integrals independent of fx volatility are cached, which can speed up calibration; remember to flush the cache when the ir parameters change, this can be done by another call to cache

value()

Real value	(	const Time	t0,
		const Time	t,
		const QuantLib::ext::shared_ptr< StrikedTypePayoff >	payoff,
