Detailed Description

template<template< class > class MC, class RNG, class S = Statistics> class QuantLib::McSimulation< MC, RNG, S >

base class for Monte Carlo engines

Eventually this class might offer greeks methods. Deriving a class from McSimulation gives an easy way to write a Monte Carlo engine.

See McVanillaEngine as an example.
