Term structure with added spread on the instantaneous forward rate.
This term structure will remain linked to the original structure, i.e., any changes in the latter will be reflected in this structure as well.
- the correctness of the returned values is tested by checking them against numerical calculations.
- observability against changes in the underlying term structure and in the added spread is checked.
Member Function Documentation
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.
Reimplemented from TermStructure.
Rate zeroYieldImpl (Time) const [protected], [virtual]
Returns the zero yield rate for the given date calculating it from the instantaneous forward rate $ f(t) $ as [ z(t) = int_0^t f( au) d au ]
This default implementation uses an highly inefficient and possibly wildly inaccurate numerical integration. Derived classes should override it if a more efficient implementation is available.
Reimplemented from ForwardRateStructure.
