Detailed Description

Scenario Generator using LGM model paths.

The generator expects

a calibrated model,
an associated multi path generator (i.e. providing paths for all factors of the model ordered as described in the model),
a scenario factory that provides building scenario class instances,
the configuration of market curves to be simulated
a simulation date grid that starts in the future, i.e. does not include today's date
the associated time grid including t=0

Member Function Documentation

void reset ( )

overridevirtual

Reset the generator so calls to next() return the first scenario.

This allows re-generation of scenarios if required.
