Detailed Description

Base class for cross asset model implied year on year inflation term structures.

The termstructure has the reference date of the model's term structure at construction, but you can vary this as well as the state. Note that this term structure does not implement the full YoYInflationTermStructure interface. It is questionable whether it should derive from YoYInflationTermStructure at all.

Constructor & Destructor Documentation

◆ YoYInflationModelTermStructure()

YoYInflationModelTermStructure	(	const boost::shared_ptr< CrossAssetModel > &	model,
		QuantLib::Size	index,
		bool	indexIsInterpolated
	)

Constructor taking the cross asset model, model, and the index of the relevant inflation component within the model, index.

Member Function Documentation

◆ yoyRate()

QuantLib::Real yoyRate	(	const QuantLib::Date &	d,
		const QuantLib::Period &	obsLag = `-1 *QuantLib::Days`,
		bool	forceLinearInterpolation = `false`,
		bool	extrapolate = `false`
	)		const

Hides the YoYInflationTermStructure::yoyRate method. The parameters forceLinearInterpolation and extrapolate are ignored.

◆ yoyRates()

virtual std::map<QuantLib::Date, QuantLib::Real> yoyRates	(	const std::vector< QuantLib::Date > &	dates,
		const QuantLib::Period &	obsLag = `-1 *QuantLib::Days`
	)		const

pure virtual

Return the year-on-year rates for the maturities associated with dates. If an obsLag is explicitly provided and not set to -1 * QuantLib::Days, it is used as the observation lag. Otherwise, the term structure's observation lag is used.

Implemented in JyImpliedYoYInflationTermStructure, and DkImpliedYoYInflationTermStructure.

◆ checkState()

virtual void checkState ( ) const

protectedvirtual

Override this method to perform checks on the state variable array when the state and move methods are called.

Reimplemented in JyImpliedYoYInflationTermStructure, and DkImpliedYoYInflationTermStructure.
