## Detailed Description

base class for interest rate indexes

## Member Function Documentation

## name()

std::string name | ( |  | ) | const

virtual

Returns the name of the index.

Warning:
  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.

## fixing()

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.

## update()

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.
