Detailed Description

base class for interest rate indexes

Possible enhancements

add methods returning InterestRate

Member Function Documentation

std::string name () const [virtual]

Returns the name of the index.


This method is used for output and comparison between indexes. It is not meant to be used for writing switch-on-type code.

Implements Index.

Reimplemented in BMAIndex.

Rate fixing (const Date & fixingDate, bool forecastTodaysFixing = false) const [virtual]

returns the fixing at the given date

the date passed as arguments must be the actual calendar date of the fixing; no settlement days must be used.

Implements Index.

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.
