Detailed Description
Hazard-rate term structure.
This abstract class acts as an adapter to DefaultProbabilityTermStructure allowing the programmer to implement only the survivalProbabilityImpl(Time) method in derived classes.
Hazard rates and default densities are calculated from survival probabilities.

Member Function Documentation
◆ defaultDensityImpl()
instantaneous default density at a given time
implemented in terms of the survival probability \( S(t) \) as \( p(t) = -\frac{d}{dt} S(t). \)
- Warning:
- This implementation uses numerical differentiation, which might be inefficient and inaccurate. Derived classes should override it if a more efficient implementation is available.
Implements DefaultProbabilityTermStructure.
