Detailed Description
Forward-rate term structureThis abstract class acts as an adapter to TermStructure allowing the programmer to implement only the forwardImpl(const Date&, bool) method in derived classes. Zero yields and discounts are calculated from forwards.
Rates are assumed to be annual continuous compounding.
Member Function Documentation
DiscountFactor discountImpl (Time t) const [protected, virtual]
Returns the discount factor for the given date calculating it from the instantaneous forward rate.Implements YieldTermStructure.
Reimplemented in CompoundForward.
Rate zeroYieldImpl (Time t) const [protected, virtual]
Returns the zero yield rate for the given date calculating it from the instantaneous forward rate. Warning
- This is just a default, highly inefficient and possibly wildly inaccurate implementation. Derived classes should implement their own zeroYield method.
Reimplemented in CompoundForward, InterpolatedForwardCurve< Interpolator >, and ForwardSpreadedTermStructure.
