public interface AnnuityMapping
An interface for calsses providing annuity mappings. An annuity mapping allows to treat swap annuity as a function of the swap rate. More precisely it is a function \( \alpha \)
such that
\[
\alpha(x) = E^A [ \frac{A(0)}{A(T)}  S(T) = x ] \, .
\]
Where A is the (froward) annuity and S is the swap rate at the given time.

getFirstDerivative
double getFirstDerivative(double swapRate) Return the first derivative of the annuity mapping for the given swap rate. Parameters:
swapRate
 The swap rate at which to evaluate the annuity mapping. Returns:
 The first derivative of the annuity mapping.

getSecondDerivative
double getSecondDerivative(double swapRate) Return the second derivative of the annuity mapping for the given swap rate. Parameters:
swapRate
 The swap rate at which to evaluate the annuity mapping. Returns:
 The second derivative of the annuity mapping.
