How to create a process with local vol only

[Lapin]

Hi,

I have a calibrated local vol, but no implied vol.
I would like to register a process (BS type), that stil works in the MC simulation framework.
Is it enough to create a derived class of GeneralizedBlackScholesProcess class with the good constructor?

The diffusion method is already calling the local vol to diffuse the underlying so in this case it should be enough.

Am I wrong?

cheers
