Detailed Description

purely virtual base class for indexes

Warning:

this class performs no check that the provided/requested fixings are for dates in the past, i.e. for dates less than or equal to the evaluation date. It is up to the client code to take care of possible inconsistencies due to "seeing in the future"

Definition at line 44 of file index.hpp.

Constructor & Destructor Documentation

~Index()

~Index ( )

overridedefault

Member Function Documentation

name()

virtual std::string name ( ) const

pure 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.

Implemented in EquityIndex, InflationIndex, and InterestRateIndex.

Here is the caller graph for this function:

fixingCalendar()

virtual Calendar fixingCalendar ( ) const

pure virtual

returns the calendar defining valid fixing dates

Implemented in EquityIndex, InflationIndex, and InterestRateIndex.

isValidFixingDate()

virtual bool isValidFixingDate ( const Date &  fixingDate ) const

pure virtual

returns TRUE if the fixing date is a valid one

Implemented in InflationIndex, BMAIndex, EquityIndex, and InterestRateIndex.

Here is the caller graph for this function:

hasHistoricalFixing()

bool hasHistoricalFixing

(

const Date &

fixingDate

)

const

returns whether a historical fixing was stored for the given date

Definition at line 138 of file index.hpp.

Here is the call graph for this function:

fixing()

virtual Real fixing ( const Date &  fixingDate, bool  forecastTodaysFixing = false  ) const

pure 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.

Implemented in EquityIndex, ZeroInflationIndex, YoYInflationIndex, InterestRateIndex, and InflationIndex.

Here is the caller graph for this function:

timeSeries()

const TimeSeries< Real > & timeSeries

(

)

const

returns the fixing TimeSeries

Definition at line 65 of file index.hpp.

Here is the call graph for this function:

Here is the caller graph for this function:

allowsNativeFixings()

virtual bool allowsNativeFixings ( )

virtual

check if index allows for native fixings.

If this returns false, calls to addFixing and similar methods will raise an exception.

Reimplemented in SwapSpreadIndex.

Definition at line 72 of file index.hpp.

Here is the caller graph for this function:

addFixing()

void addFixing ( const Date &  fixingDate, Real  fixing, bool  forceOverwrite = false  )

virtual

stores the historical 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.

Reimplemented in InflationIndex.

Definition at line 24 of file index.cpp.

Here is the call graph for this function:

addFixings() [1/2]

void addFixings	(	const TimeSeries< Real > &	t,
		bool	forceOverwrite = false
	)

stores historical fixings from a TimeSeries

the dates in the TimeSeries must be the actual calendar dates of the fixings; no settlement days must be used.

Definition at line 33 of file index.cpp.

Here is the call graph for this function:

Here is the caller graph for this function:

addFixings() [2/2]

void addFixings	(	DateIterator	dBegin,
		DateIterator	dEnd,
		ValueIterator	vBegin,
		bool	forceOverwrite = false
	)

stores historical fixings at the given dates

the dates passed as arguments must be the actual calendar dates of the fixings; no settlement days must be used.

Definition at line 88 of file index.hpp.

Here is the call graph for this function:

clearFixings()

void clearFixings

(

)

clears all stored historical fixings

Definition at line 45 of file index.cpp.

Here is the call graph for this function:

checkNativeFixingsAllowed()

void checkNativeFixingsAllowed ( )

private

check if index allows for native fixings
