Calculations | |
These methods must be implemented in derived classes to perform the actual calculations. When they are called, range check has already been performed; therefore, they must assume that extrapolation is required. | |

Forward-rate term structure
This abstract class acts as an adapter to YieldTermStructure allowing the programmer to implement only the forwardImpl(Time)
method in derived classes.
Zero yields and discounts are calculated from forwards.
Forward rates are assumed to be annual continuous compounding.

instantaneous forward-rate calculation
Implemented in InterpolatedForwardCurve< Interpolator >, and ForwardSpreadedTermStructure.
Returns the zero yield rate for the given date calculating it from the instantaneous forward rate \( f(t) \) as
\[ z(t) = \int_0^t f(\tau) d\tau \]
Reimplemented in InterpolatedForwardCurve< Interpolator >, and ForwardSpreadedTermStructure.

Returns the discount factor for the given date calculating it from the zero rate as \( d(t) = \exp \left( -z(t) t \right) \)
Implements YieldTermStructure.
