Member Function Documentation

◆ performCalculations()

void performCalculations ( ) const

overridevirtual

This method must implement any calculations which must be (re)done in order to calculate the desired results.

Implements LazyObject.

Definition at line 196 of file interpolatedsmilesection.hpp.

◆ varianceImpl()

Real varianceImpl ( Rate strike ) const

overridevirtual

Reimplemented from SmileSection.

◆ volatilityImpl()

Volatility volatilityImpl ( Rate strike ) const

overridevirtual

Implements SmileSection.

◆ minStrike()

Real minStrike ( ) const

overridevirtual

Implements SmileSection.

Definition at line 81 of file interpolatedsmilesection.hpp.

◆ maxStrike()

Real maxStrike ( ) const

overridevirtual

Implements SmileSection.

Definition at line 82 of file interpolatedsmilesection.hpp.

◆ atmLevel()

Real atmLevel ( ) const

overridevirtual

Implements SmileSection.

Definition at line 83 of file interpolatedsmilesection.hpp.

Here is the caller graph for this function:

◆ update()

void update ( )

overridevirtual

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.
