base floating-rate coupon class

Member Function Documentation

Real amount () const [virtual]

returns the amount of the cash flow


The amount is not discounted, i.e., it is the actual amount paid at the cash flow date.

Implements CashFlow.

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.

Reimplemented in CappedFlooredCoupon, and DigitalCoupon.
