Pricing engines and models

[Carles Jou]

Hi,

I'm new at Quantlib. After reading the available documentation, I was wondering why pricing engines can be model independent.

To the best of my understanding, each pricing engine should stem from a model which would specify the behaviour of the underlyings.

I would be grateful if anybody could help me understand the reasons behind this choice.

Carles

Carles,
        most of them are model-dependent.  What are the ones that are  
puzzling you?

Later,
