Member Function Documentation

◆ baseDate()

Date baseDate ( ) const
virtual

minimum (base) date

Important in inflation since it starts before nominal reference date. Changes depending whether index is interpolated or not. When interpolated the base date is just observation lag before nominal. When not interpolated it is the beginning of the relevant period (hence it is easy to create interpolated fixings from a not-interpolated curve because interpolation, usually, of fixings is forward looking).

Reimplemented from InterpolatedZeroInflationCurve< Interpolator >.

◆ 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.

Reimplemented from LazyObject.
