Detailed Description

Base inflation-coupon pricer.

The main reason we can't use FloatingRateCouponPricer as the base is that it takes a FloatingRateCoupon which takes an InterestRateIndex and we need an inflation index (these are lagged).

The basic inflation-specific thing that the pricer has to do is deal with different lags in the index and the option e.g. the option could look 3 months back and the index 2.

We add the requirement that pricers do inverseCap/Floor-lets. These are cap/floor-lets as usually defined, i.e. pay out if underlying is above/below a strike. The non-inverse (usual) versions are from a coupon point of view (a capped coupon has a maximum at the strike).

We add the inverse prices so that conventional caps can be priced simply.

Member Function Documentation

virtual void update () [virtual]

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.

Implements Observer.
