Detailed Description

Analytic Heston engine incl. stochastic interest rates.

This class is pricing a european option under the following process

\[ \begin{array}{rcl} dS(t, S) &=& (r-d) S dt +\sqrt{v} S dW_1 \\ dv(t, S) &=& \kappa (\theta - v) dt + \sigma \sqrt{v} dW_2 \\ dr(t) &=& (\theta(t) - a r) dt + \eta dW_3 \\ dW_1 dW_2 &=& \rho dt \\ dW_1 dW_3 &=& 0 \\ dW_2 dW_3 &=& 0 \\ \end{array} \]

This method must be implemented in derived classes. An instance of Observer does not call this method directly: instead, it will be called by the observables the instance registered with when they need to notify any changes.

Reimplemented from GenericEngine< ArgumentsType, ResultsType >.
